Single-name entries

This is a reconciliation report — it carries no single-name score table. Recaps are structured around hit-rate reconciliation, theme verification and next-day outlook.

⚠️ Risk disclaimer (up front): This recap is post-close information review and observation only. It does not constitute investment advice and contains no ratings, target prices, position sizing or buy/sell recommendations. The terms "delivered / did not deliver / called right / called wrong" used below are strictly an after-the-fact reconciliation against this morning's pre-market list, and imply nothing about future returns.

Data-basis disclosure first (please read this section before anything else)

  1. Time window: 2026-07-31 09:15 (call auction) → 15:30 (cut-off for this report). Today is Friday and the last trading day of July.
  2. Market data sources: index and single-stock closing prices use Sina full-market quotes stock_zh_a_spot (5529 valid samples, timestamp 15:30:02); limit-ups / limit-up breaks / performance of yesterday's limit-up names use East Money pools stock_zt_pool_em / stock_zt_pool_zbgc_em / stock_zt_pool_previous_em; industry moves and net inflows use THS industry aggregates stock_board_industry_summary_ths (90 industries); northbound/southbound use stock_hsgt_fund_flow_summary_em.
  3. ⚠️ Data gap #1 (must be disclosed, and it is today's single most important gap) — block-trade disclosure list (Dragon-Tiger list) not obtained: stock_lhb_detail_em(20260731) returned an empty object at 15:40 (exchange Dragon-Tiger lists are usually published around 18:00 after the close). This entire report contains no 7/31 Dragon-Tiger figures whatsoever; anywhere seat-level direction is involved it is written as "cannot be confirmed at this time", with no speculation. This is logged as an outstanding item that tomorrow morning's pre-market list must fill in (see Section 6.4).
  4. ⚠️ Data gap #2 — no valid basis for single-day northbound net flow: stock_hsgt_fund_flow_summary_em returns 0.000 for the "net buy turnover" of both the Shanghai Connect and Shenzhen Connect northbound records. This is not "net buying of zero"; it is a null value returned by the interface after the exchanges discontinued single-day net-buy disclosure from August 2024. This report does not use it as 0 and writes "no reliable data available"; only the still-valid parts of that interface — the advance/decline counts of northbound-eligible names and southbound net buying — are used. This is the third consecutive day with this same gap.
  5. ⚠️ Data gap #3 — East Money industry/concept boards and fund-flow rankings failed across the board: stock_board_industry_name_em, stock_board_concept_name_em and stock_sector_fund_flow_rank returned ConnectionError / 502 Bad Gateway / JSONDecodeError respectively. All sector moves and net inflows in this report are on the THS basis, which is the same source as the THS basis cited in this morning's pre-market list and is therefore comparable across days; but it is not comparable across sources with the "industry" classification used by the East Money limit-up pool — every place below where counts are compared has the basis labelled.
  6. ⚠️ Two different bases exist for the limit-up count; this report discloses both side by side: the East Money limit-up pool stock_zt_pool_em shows 99 names; Sina Finance's closing commentary shows 88 stocks at limit-up. The source of the difference has not been verified (it may involve ST stocks, the Beijing Stock Exchange, or whether new listings are included). The body of this report uses the East Money pool figure of 99 throughout, and hereby states that the other basis exists.
  7. What this report does not do: it uses no narrative of the form "today's outcome proves the pre-market call was right all along". Section 8 of this morning's pre-market list wrote down 6 sector criteria, 5 single-stock criteria and 10 risk signals of its own accord. The reconciliation in this report is measured against those observable conditions already written down in black and white before the open, not against standards invented after the fact. Where the call was wrong, it is recorded as wrong.

0. One-line recap

Today's sentiment temperature: euphoric (but a "split euphoria") — 99 limit-ups, 0 limit-downs, 4690 advancers, an all-A median of +2.03%; at the index level it was the strongest day since the start of July. But there were 107 limit-up breaks, a 51.9% break rate, and almost none of the names that gapped up held their gains.

Today's strongest theme was neither "AI hardware oversold bounce" — ranked #1 on this morning's pre-market list — nor "memory price hikes" ranked #2, but "domestic AI applications / software / media", which appeared in the pre-market list only as a single C-rated ChinaJoy headline. Of THS's 90 industries, the top 8 gainers were, in order, IT services +6.29%, software development +6.15%, automation equipment +5.34%, cultural media +5.28%, film & cinema +4.97%, computer equipment +4.60%, gaming +4.50%, communication services +4.47%semiconductors at +4.23% ranked only 10th, and components at +4.33% ranked 9th.

And the answer from money flows is sharper than the price moves: software development net inflow +RMB 9.029 billion, IT services +RMB 5.465 billion, cultural media +RMB 4.795 billion — the top three of the entire market; semiconductors net outflow −RMB 20.502 billion and components net outflow −RMB 7.289 billion — the bottom two of the entire market (THS industry net-inflow basis). In other words, the two sectors that rose most violently today, semiconductors and components, were the two most heavily sold — "price up, money out". This is the sector-level amplification of the same pattern logged in yesterday's recap: "德明利 (Demingli Electronics) hit limit-up but showed RMB 706 million of net Dragon-Tiger selling".

Pre-market list hit summary: of the 30 main-board names on the main list, 12 hit on the strict basis (40.0%), and 15 on the loose basis (partial delivery counted as half) (50.0%). By tier the differences are stark: "watch only" was right on 6 of 7 (85.7%), the most accurate tier on the whole list; "priority deep-dive" delivered 2 of 4; "watch closely" delivered strictly on only 4 of 18; and the 2 "dual-dimension Pass" names — 太极实业 (Taiji Industry, 600667) and 江海股份 (Nantong Jianghai Capacitor, 002484) — were 0/2, both called wrong, with 太极实业 closing at a locked limit-up of +10.03%.

Tone for tomorrow (Monday 8/3): the theme rotation has already happened, but the new theme (AI applications) is itself in the high-risk position of "day 1 of launch + a 51.9% limit-up break rate at elevated levels", while the old theme (AI hardware / memory) is in a "index up, money out" divergence. The tone is set as a divergence day: neither continuation nor washout, but a day that must be characterised by two things — "can AI applications produce a second consecutive limit-up" and "can semiconductor money flow turn from negative to positive".


1. Market overview

1.1 Indices and turnover (Sina basis, timestamp 15:30:02)

Index Close Change % Change (pts) Notes
SSE Composite 3832.26 +0.73% +27.57 Reclaimed 3800; heavyweights (banks/baijiu) a clear drag
SZSE Component 13578.93 +2.21% +293.13
ChiNext Index 3343.96 +3.06% +99.35 Was +5.15% at the open (The Paper's basis); gave back about 2 percentage points over the day
STAR 50 1635.96 +2.99% +47.55 The STAR Market Composite was up more than 6%–7% intraday
CSI 300 4588.20 +0.85% +38.48
  • Turnover: Shanghai RMB 1.19 trillion, Shenzhen RMB 1.35 trillion, combined roughly RMB 2.54 trillion (RMB 2.56 trillion on the all-A basis including the Beijing Stock Exchange). A clear expansion versus yesterday, and the one uncontested piece of positive evidence in this bounce.
  • ⚠️ The single most important fact at the index level: all three major indices traced a "gap up → fade", not a "gap down → rally". The ChiNext Index opened +5.15% and closed +3.06%; the STAR Market Composite was up over 6% intraday and the STAR 50 closed +2.99%. Today's high came near the open, and that single fact determines the character assessment of every stock below.

1.2 Sentiment indicators

Sentiment temperature over the last 6 trading days (East Money pool basis)

Date Limit-ups Limit-downs Breaks Break rate Read
07-24 40 25 11 21.6% Weak
07-27 111 6 13 10.5% Climax
07-28 61 49 20 24.7% Divergence
07-29 81 9 14 14.7% Repair
07-30 52 74 19 26.8% Freezing point
07-31 99 0 107 51.9% Euphoric but split

1.3 Sentiment call: euphoric, but lower quality than the 7/27 climax

Three pieces of evidence, side by side, none dispensable:

  1. Positive: limit-downs to zero, 4690 advancers, turnover expanding to RMB 2.54 trillion, 99 limit-ups — every breadth indicator is the best of the week.
  2. Negative: a 51.9% limit-up break rate, the highest of the week and almost 5 times that of the 7/27 climax day (10.5%). On two days that both had "about 100 limit-ups", 7/27 saw only 13 breaks while today saw 107 — the two days are completely different in character: 7/27 was a climax with ample follow-through; today was a broad rally with insufficient follow-through.
  3. Structurally negative: by industry, the limit-up-break pool was led by components with 15 names and semiconductors with 8 — the heaviest breakage happened precisely in the chain this morning's pre-market list pushed hardest.

Conclusion: today was a "broad rally with limit-downs at zero", not a "theme confirmation day". Summed up in one figure: 879 stocks rose more than 5%, but only 99 held a limit-up, while 107 reached limit-up and failed to hold it.

1.4 One macro data point unconfirmed pre-market that landed today

The July official manufacturing PMI was published today at 09:30: 49.2%, down 1.1 percentage points month-on-month (non-manufacturing business activity index 49.0%, −1.2 m/m; composite PMI output index 49.3%, −1.3; production index 49.9% and new orders index 48.5%, −1.5 and −2.7 respectively).

  • Item 8 of Section 8.4 of this morning's pre-market list explicitly wrote: "this report could not verify today's exact release schedule or market expectations, so it falls under 'no reliable data available' — please confirm it yourself before the open, as it could change the tape the instant trading starts". The outcome: the data was released as usual and was clearly weaker (the Nth consecutive month below the boom/bust line, with a large m/m drop), and the market ignored it entirely, with indices gapping up and running higher.
  • But there is one structure within it that is highly consistent with today's tape: equipment manufacturing PMI 51.4% and high-tech manufacturing PMI 53.3%, clearly above the manufacturing total and still expanding briskly; consumer goods 47.8% and energy-intensive industries 47.0%. The divergence of "high-tech expanding, consumption and energy-intensive contracting" points in the same direction as today's tape structure — technology/AI applications sharply higher, baijiu +0.63%, banks −0.77%, coal +0.82%.
  • Lesson for the recap (usable tomorrow morning): flagging the PMI as an "unconfirmed risk" pre-market was correct, but it only said "could change the tape" and did not spell out the branch: "if the data is weak but internally divergent (high-tech strong, consumption weak), the tape may rise rather than fall and style divergence may widen". Next time an unconfirmed macro release comes up, give a two-sided scenario rather than a one-directional risk warning.

2. Reconciliation against the pre-market list

Judging benchmark (standard set first, reconciliation second, to avoid hindsight): today's all-A median change was +2.03% and the SZSE Component was +2.21%. On that basis, for the "priority deep-dive / watch closely" tiers: a close of ≥ +5.00% counts as "delivered"; +2.03%~+5.00% counts as "partially delivered"; < +2.03% counts as "did not deliver". For the "watch only" tier: a gain below the all-A median counts as "called right", ≥ +5% counts as "called wrong". For the "Pass" tier: a limit-up or a large gain counts as "called wrong". Open % and high % are listed alongside, because "the open was the high" was today's dominant pattern across the market, and looking only at the close would badly misread it.

2.1 Priority deep-dive (4 names)

Stock Pre-market conclusion Open % High % Today's change % Limit-up / break Delivered? Comment
长电科技 (JCET Group, 600584) Priority deep-dive (ranked #1 in Section 9.1) +8.93 +8.93 +1.86 No limit-up, no break Did not deliver ⚠️ The most glaring line on the whole list: the opening price was the high of the day, after which it fell in a straight line and closed with only 1.86% left. The pre-market verification point set for it was "auction gap-up of more than 4% + does not break the opening price in the first 5 minutes" — the first half held (gapped up 8.93%), the second half failed immediately. Turnover RMB 10.901 billion (yesterday RMB 10.647 billion), rising volume without a rise in price — the textbook confirmation of "yesterday's +RMB 317 million of net buying from the fifth-largest buy seat was passive absorption". The reason it was ranked #1 pre-market was "money-flow direction is positive"; today proves that Dragon-Tiger net buying equal to 3.0% of turnover is, exactly as the pre-market note itself flagged, only a weak signal, insufficient to support a ranking.
沪电股份 (WUS Printed Circuit, 002463) Priority deep-dive +9.06 +10.01 (touched limit-up intraday) +7.46 6 limit-up breaks Delivered The best name in the "priority deep-dive" tier today, and the most successful call on the entire list. Its pre-market verification point was "do 生益, 深南 and 东山 all close green alongside it" — all four closed green (沪电 +7.46, 生益 +5.56, 深南 +8.26, 东山 +5.98), so the condition held in full. The pre-market assessment of "fundamentals 12.5/15, the highest on the list" got its corresponding payoff on the tape today. The one blemish: 6 limit-up breaks, showing that the bid absorption at the limit is still insufficient.
兆易创新 (GigaDevice, 603986) Priority deep-dive +10.00 (one-line limit-up at the open) +10.00 +2.02 1 limit-up break Did not deliver ⚠️ A worse pattern than 长电: one-line limit-up at the open → break → closed with only 2.02% left, giving back nearly 8 percentage points over the day, with a close below the all-A median of 2.03%. Turnover RMB 34.043 billion (yesterday RMB 35.484 billion), huge volume without a rise. The pre-market verification point set for it was "can the memory chain produce a 2nd and 3rd main-board limit-up" — see Section 2.4 below; this one failed in the most ironic way possible.
工业富联 (Foxconn Industrial Internet, 601138) Priority deep-dive +6.21 +7.01 +5.39 No limit-up Delivered Pre-market it was defined as the "authenticity discriminator": if its strength were weaker than the limit-down names, that would mean this was merely an oversold bounce. Today it gave a mixed signal, and both sides must be written down: ① its opening move (+6.21%) was clearly smaller than yesterday's limit-down names (长电 opened +8.93, 生益 opened +10.00, 东山 opened +9.39); ② but its close (+5.39%) was clearly higher than theirs (长电 +1.86, 通富 +1.50, 兆易 +2.02). Conclusion: judged by the open it was an "oversold bounce", judged by the close money really is favouring the end with solid fundamentals. This was the most discriminating of the verification conditions designed pre-market.

Priority deep-dive delivery rate: 2/4 (50%).

2.2 Watch closely (18 names)

Stock Open % Today's change % Status Delivered? Comment
深南电路 (Shennan Circuits, 002916) +9.67 +8.26 13 limit-up breaks Delivered The strongest close of the four AI PCB names, while pre-market it was rated "lowest growth + higher valuation" and ranked 8th. This is the clearest case of the pre-market ranking being contradicted: the name ranked last within the branch rose the most.
光迅科技 (Accelink Technologies, 002281) +7.87 +6.12 14 limit-up breaks, touched limit-up intraday Delivered ⚠️ Pre-market spent an entire section arguing "do not treat it as the main-board version of 中际旭创" (overseas revenue down consecutively to 26.7%, PE 121.7×) and downgraded it. Today it rose +6.12%, beating 中际旭创 (Innolight, 300308) at +4.40%. The fundamental downgrade was right, but on today's share-price direction it was wrong — once again confirming the pre-market list's own line, "an earnings-dimension Pass ≠ claiming it will not rise".
东山精密 (Suzhou Dongshan Precision, 002384) +9.39 +5.98 3 limit-up breaks Delivered Pre-market listed "Apple −6% after hours" as a reverse risk for it and excluded it from the watch scope (Section 9.3). That risk did not materialise: consumer electronics +3.49%, and the Apple chain did not weaken on its own. Turnover RMB 21.468 billion, the largest of any main-board name.
生益科技 (Shengyi Technology, 600183) +10.00 +5.56 17 limit-up breaks Delivered After a one-line limit-up at the open it broke the limit 17 times over the day, one of the most frequently broken large caps in the market. Delivered, but the path was awful.
浪潮信息 (Inspur Electronic Information, 000977) +7.09 +3.95 Partially delivered Pre-market devoted a whole item (Section 9.3) to arguing "do not treat it as an AWS/Microsoft capex beneficiary" (BIS entity-list status pending verification, Q1 revenue −24.3%). Today it rose +3.95%, weaker than 工业富联's +5.39%the relative ranking was right, the absolute direction was not.
紫光股份 (Unisplendour, 000938) +3.87 +3.84 Partially delivered ⚠️ It had the mildest "gap up and dive" on the whole list (opened +3.87 / closed +3.84), with turnover expanding from RMB 8.755 billion yesterday to RMB 14.167 billion. The pre-market verification point was "it forms a cross-check with 长电; if both are strong at the same time, the money-flow character of the bounce is established" — the outcome was that 紫光 held while 长电 collapsed, so the cross-check does not hold.
华天科技 (Tianshui Huatian Technology, 002185) +7.38 +3.76 Partially delivered The strongest of the three packaging & testing leaders today, while pre-market it was ranked 3rd within that group. Another within-branch ranking contradicted.
长飞光纤 (YOFC, 601869) +8.51 +3.37 Partially delivered
中科曙光 (Sugon, 603019) +6.00 +3.04 Partially delivered
深科技 (Shenzhen Kaifa, 000021) +8.46 +2.22 Partially delivered Pre-market characterised it as "memory exposure diluted to 15%, unsuitable as a branch representative"; today's +2.22% sat essentially on the median, so the characterisation was accurate.
通富微电 (Tongfu Microelectronics, 002156) +5.56 +1.50 Did not deliver The weakest of the three packaging & testing leaders. Pre-market ranked it behind 长电 because of "Dragon-Tiger net selling, 4 institutions selling"; that relative ranking held today (1.50% < 长电's 1.86%), but neither delivered, so getting the ranking right is meaningless.
亨通光电 (Hengtong Optic-Electric, 600487) +6.99 +0.87 Did not deliver Gapped up +6.99 and closed +0.87, giving back 6 percentage points.
英维克 (Shenzhen Envicool, 002837) +5.20 +0.64 Did not deliver
紫光国微 (Unigroup Guoxin, 002049) +3.86 +0.50 Did not deliver Pre-market explicitly wrote "resilience on the way down means there is no oversold-bounce room" — the single most precise micro call on the whole list today; +0.50% was dead last within the entire chain.
剑桥科技 (Cambridge Technology, 603083) +6.48 +0.09 Did not deliver Opened +6.48, high +9.01, closed +0.09 — gave back 9 percentage points over the day, the worst dive in this tier.
德明利 (Demingli Electronics, 001309) +10.00 (one-line limit-up at the open) −1.06 1 limit-up break, closed red Did not deliver (and in the opposite direction) ⚠️⚠️ The single most important name of the day. The criterion written pre-market was: "a one-line limit-up = yesterday's net selling has been covered by today's buying, and the branch strength is revised up; a gap-up-and-fade = the RMB 706 million of Dragon-Tiger net selling is confirmed, and this report's 'watch closely' tag on it is void". Today's pattern: one-line limit-up at the open → break → closed −1.06% in the red, turnover RMB 17.355 billion, turnover rate 25.61%. By the rule the pre-market list set for itself in black and white, the "watch closely" tag is automatically void. Yesterday's RMB 706 million of net selling was fully confirmed today.
通威股份 (Tongwei, 600438) −1.11 −0.09 Did not deliver The representative name of the solar branch closed in the red for the whole day; the substantive catalyst from today's Yancheng meeting was zero, see Section 3.
工商银行 (ICBC, 601398) −2.21 −1.96 Did not deliver (but the seesaw call was right) Pre-market explicitly wrote "it is a seesaw against branches 1 and 2: the day technology bounces is usually the day banks cool off" — today banks −0.77% (9 up, 32 down) and insurance −0.70% were the worst in the market, so the seesaw held completely. As an "allocation-attribute" name it did not deliver, but as a "seesaw criterion" the call was right.

Watch closely tier: strictly delivered 4/18 (22.2%), including partial delivery 10/18 (55.6%).

2.3 Watch only (7 names) — the most accurate tier on the whole list

Stock Open % Today's change % Called right? Comment
永鼎股份 (Jiangsu Yongding, 600105) +6.98 −2.79 Called right The most precise call on the entire list. Pre-market wrote "the good news is real, but the price has already run ahead of the news", and calculated "single-day market-cap increment of RMB 3.289 billion ÷ roughly RMB 47 million of annualised net profit attributable to parent after equity look-through ≈ 70x". On a broad rally day with 4690 advancers and only 728 decliners, it was one of the few large caps to close green-to-red, opening +6.98 and closing −2.79. This methodology, which fully separates "the news is real" from "should you chase it", was completely validated today.
陆家嘴 (Shanghai Lujiazui, 600663) +0.48 −3.02 Called right Pre-market wrote "it already completed a round of repricing around the Politburo meeting reports, and day 2 is a high-level relay". Today it broke its limit-up streak at −3.02%, and was the 3rd worst performer among yesterday's 52 limit-up names.
风华高科 (Fenghua Advanced Technology, 000636) +10.00 (one-line open) −2.28 Called right ⚠️ Pre-market wrote "the price-hike letter is real, but the market has already voted it down once with its feet". Today's pattern is identical to 德明利's: one-line limit-up at the open → break → closed −2.28%, turnover RMB 13.582 billion, turnover rate 22.10%. The day before the MLCC price increase takes effect on 8/1 ended with "gapped up, closed red".
海兴电力 (Hexing Electrical, 603556) −3.67 0.00 Called right Pre-market wrote "2 consecutive limit-ups means it has entered the relay phase" + reverse evidence on the grid equipment sector. Today it closed flat; grid equipment +2.05% with net outflow of RMB 231 million, clearly underperforming the market.
隆基绿能 (LONGi Green Energy, 601012) −1.08 −0.23 Called right
舍得酒业 (Shede Spirits, 600702) −3.44 +3.44 Called right (did not reach the +5% threshold) ✅ Opened down −3.44 then turned positive at +3.44; the baijiu sector was up only +0.63% overall (14 up, 5 down). The pre-market question "today is a falsification day; baijiu has to prove it can hold up even when technology bounces" is answered as "it did not hold up, but it did not collapse either".
江淮汽车 (JAC Motors, 600418) −3.61 +7.71 Called wrong ⚠️ Pre-market wrote "limit-up but Dragon-Tiger net selling of −RMB 393 million… high turnover wash trading rather than position locking" and assigned watch only. Today it opened −3.61% and ran all the way to +7.71%, one of the few large caps in the market to gap down and run higher. The auto OEM sector rose only +0.24% today (11 up, 10 down), ranking 7th from the bottom — which shows this was clearly stock-specific behaviour rather than sector behaviour, and the pre-market analytical framework has no dimension capable of capturing independent single-stock behaviour.

Watch only tier accuracy: 6/7 (85.7%).

2.4 Pass-list reconciliation — today's biggest misjudgement is here

Stock / direction Pre-market Pass type Today's change % Called right? Comment
太极实业 (Taiji Industry, 600667) Dual-dimension Pass (pre-market called it "the most important falsification in this report" and listed it first in Section 9.3) +10.03 (one-line limit-up at the open, locked all day) Called wrong ❌❌ ⚠️⚠️⚠️ Today's single biggest misjudgement on the whole list; it must be laid out separately:① Facts: 太极实业 sealed a one-line limit-up at 09:25:04, broke it 4 times over the day and then re-sealed it, closing +10.03% on turnover of RMB 6.338 billion with a turnover rate of 17.66%the largest turnover of all 87 main-board limit-up stocks today.② The pre-market Pass rationale itself has not been overturned: the company's 2026-06-26 Announcement on Abnormal Share Trading Fluctuations (Interim 2026-039) states verbatim that it is "relatively little affected by the industry's upcycle" and "does not involve HBM products"; 海太 (Hitech Semiconductor) uses a cost-plus foundry model of "full cost + agreed return"; across a full three-year cycle net profit was RMB 219.1 / 237.1 / 239.1 million, a swing of less than 10%. These are company-announcement-grade pieces of evidence, and nothing published today overturns them.③ What the market traded today is a directly conflicting narrative: numerous media outlets and aggregator pages describe it as a "scarce HBM3E packaging & testing name", claim "海太 handles 40%–50% of global DRAM back-end packaging & testing", and that "海太 has received additional investment from SK Hynix and its FCBGA advanced packaging validation has landed". ⚠️ This report has obtained these claims only from self-media/aggregator sources, has obtained no original company announcement, and they directly contradict the company's own 6/26 announcement; therefore this report does not accept them and does not cite any of their figures as fact.④ But there is one point here that demands self-criticism: Section 6 of the pre-market list wrote down the sole overturning condition itself — "a 海太 capacity-expansion / additional-investment announcement". The market today traded on exactly that narrative. Pre-market correctly identified the overturning condition, but dismissed it in passing as a low-probability item with "zero public information at present", and designed no intraday monitoring action for it.⑤ The most critical methodological error: pre-market classified it as a "dual-dimension Pass", i.e. "the earnings and sentiment dimensions are both unsupportive, and only this category warrants non-participation". Yet today it was the largest-turnover limit-up stock on the whole main board — the sentiment dimension was not merely supportive, it was the strongest in the market. This shows the pre-market assessment of the "sentiment dimension" failed completely: judging the sentiment dimension unsupportive purely from the 7/30 one-line limit-down ignored that "an oversold bounce after a −51.2% collapse is itself the strongest sentiment fuel there is".
江海股份 (Nantong Jianghai Capacitor, 002484) Dual-dimension Pass ("the product-category mismatch was already validated on 7/30") +5.78 Called wrong Pre-market judged a dual-dimension Pass on the basis that "江海's main business is aluminium electrolytic / film / supercapacitors, not MLCC". The factual judgement on the category mismatch still holds, but today it rose +5.78%, touched limit-up intraday, and beat the all-A median by nearly 3x. Proof once again that a category mismatch can negate "fundamental beneficiary", but it cannot negate "money is willing to trade it".
中际旭创 (Innolight, 300308) Earnings-dimension Pass (not main board + timing of share-reduction) +4.40 Partially right The Pass rationale was "not main board" and "share-reduction announcement", not a price judgement. Today it rose +4.40%, underperforming 光迅科技 (002281) at +6.12%, 新易盛 (Eoptolink, 300502) at +6.71% and 天孚通信 (T&S Communications, 300394) at +6.81% — the branch leader lagging the followers shows the share-reduction announcement did act as a cap. This one was called right. Turnover RMB 54.044 billion, still the highest in all-A.
爱丽家居 (Aili Home Furnishings, 603221) Earnings-dimension Pass (explicitly wrote "not claiming it will not rise today") +10.00 (9 consecutive limit-ups) Classification right
传智教育 (Chuanzhi Education, 003032) Earnings-dimension Pass +9.99 (5 consecutive limit-ups) Classification right ✅
香江控股 (Xiangjiang Holdings, 600162) Earnings-dimension Pass +10.03 (2 consecutive limit-ups) Classification right ✅
神雾节能 (Shenwu Energy Saving, 000820) Earnings-dimension Pass +10.00 (2 consecutive limit-ups) Classification right ✅
一鸣食品 (Yiming Foods, 605179) Earnings-dimension Pass +9.99 (4 consecutive limit-ups) Classification right ✅
明新旭腾 (Mingxin Xuteng, 605068) Earnings-dimension Pass +5.34 Classification right ✅
均瑶健康 (Junyao Health, 605388) Earnings-dimension Pass +1.47 Classification right ✅
广电电气 (Guangdian Electric, 601616) Earnings-dimension Pass −3.68 Called right ✅ The 2nd worst performer today among yesterday's 52 limit-up names.
The "宇树科技 (Unitree Robotics) supplier" mapping Dual-dimension Pass (whole category) Called right ✅ The event window is price consultation on 8/5 and subscription on 8/10; no unusual moves today, so the pre-market decision to "not give a name list" cost nothing today.
"Gold stocks associated with 赤峰黄金 (Chifeng Jilong Gold)" Earnings-dimension Pass Precious metals sector +4.00% (14 up, 0 down), 招金黄金 (Zhaojin Gold, 000506) at limit-up Partially wrong Pre-market wrote "this is a stock-specific event for 赤峰黄金 alone and does not constitute a sector positive". Today precious metals rose +4.00%, 14 up and 0 down, with net inflow of RMB 1.453 billion, and 招金黄金 (000506) hit limit-up (turnover RMB 1.804 billion, 26 limit-up breaks) — a sector-level rise did occur. But it must be stated side by side: this report has obtained no evidence that today's rise in gold stocks is causally linked to the 赤峰黄金 resource-volume news (it is more likely related to precious metal prices themselves and safe-haven factors), so the accurate statement is "the pre-market causal separation was right, but the incidental 'does not constitute a sector' price prediction made alongside it was wrong".

⭐ The single most important conclusion from the Pass tier: the two-level classification of "earnings-dimension Pass / dual-dimension Pass" introduced pre-market produced an extremely clean test result today — all 9 earnings-dimension Passes were classified correctly (they did indeed rise, and pre-market explicitly said "not claiming it will not rise"); both dual-dimension Passes (太极实业, 江海股份) were called wrong, and that is precisely the only category that argues for "do not participate". This classification framework was introduced in yesterday's recap to correct the error of "Passed it and it hit limit-up"; today proves the classification itself is sound, and the problem lies in the far-too-loose test for "which names qualify for a dual-dimension Pass".

2.5 Hit-rate summary

Tier Count Strict hits Strict hit rate Including partial Loose hit rate

Branch-ranking hits: 1/3 partially delivered (see Section 3), and the strongest theme was missed entirely.

2.6 Item-by-item reconciliation of Section 8 "observable verification conditions" from the pre-market list (the highest-information section here)

Section 8 of this morning's pre-market list said verbatim: "the observable conditions in this section take priority over the branch ranking in Section 2 and the single-stock master list in Section 3. Where the two conflict, this section governs." So this is the real report card.

8.2 Sector signals (6 items)

# Condition set pre-market Actual today Verdict
1 Semiconductors / components / communication equipment all turn positive at once, and more than 100 advancers within the semiconductor sector Semiconductors +4.23% (175 up, 8 down), components +4.33% (57 up, 5 down), communication equipment +3.98% (83 up, 7 down) (THS basis) Held
2 At least 2 of the three packaging & testing leaders (长电/通富/华天) hit limit-up or rise >7% — pre-market called this "the single most important sector criterion designed in this report" 长电 +1.86%, 通富 +1.50%, 华天 +3.76%0 qualified Failed(the most important criterion failed outright)
3 The memory chain produces a 2nd and 3rd main-board limit-up stock ("a lone name does not constitute a branch") The only main-board memory limit-up was 太极实业 (600667), and that is precisely the name pre-market Passed; 兆易创新 (603986) and 德明利 (001309) both opened at a one-line limit-up and then broke it Failed(and in the most ironic way)
4 The four AI PCB names (沪电/生益/深南/东山) all close green together with expanded turnover All four closed green: 沪电 +7.46, 生益 +5.56, 深南 +8.26, 东山 +5.98; 东山's turnover of RMB 21.468 billion was the largest on the main board Held(the only branch-level criterion that held in full)
5 Market-wide limit-ups > 70 and limit-downs < 20 99 limit-ups, 0 limit-downs Held
6 Solar produces a sector-level rise (rather than 弘元绿能 as a lone name) Solar equipment +1.83% (60 up, 9 weak), underperforming the all-A median of 2.03% and ranking 52nd of 90 industries; 弘元绿能 (Hongyuan Green Energy, 603185) +4.62%, no main-board limit-up Failed

Sector signals: 3 held / 3 failed. But among the 3 that held, items 1 and 5 are loose conditions that hold automatically on a broad rally day; the genuinely discriminating items 2, 3, 4 and 6 were 1 held / 3 failed.

8.4 Risk signals (10 items)

# Pre-market risk signal Actual today Materialised?
1 Gap up and dive — pre-market called it "in a sector that has already fallen for a month with extremely dense overhead supply, this is what this report considers the single highest-probability risk" Materialised (pattern called right, magnitude called too light): 兆易创新 opened +10.00 → closed +2.02, 德明利 opened +10.00 → closed −1.06, 风华高科 opened +10.00 → closed −2.28, 普冉股份 (PUYA Semiconductor, 688766) opened +20.00 → closed +0.50, 长电科技 opened +8.93 (= the high of the day) → closed +1.86, 剑桥科技 opened +6.48 → closed +0.09. But the specific threshold set pre-market was "falls back to flat before 10:00"; in reality most stocks still closed green for the day, so it was "a large give-back without turning red" Materialised ⚠️ (the number-one risk identified pre-market was indeed the number-one event today)
2 Lone-name limit-up Materialised: the only main-board limit-up in the memory chain was 太极实业 Materialised ⚠️
3 The core names do not follow (工业富联/兆易/沪电 weaker all day than the oversold small caps) Partially materialised: 兆易 at +2.02 was indeed very weak; but 沪电 +7.46 and 工业富联 +5.39 were both stronger than the oversold names Partially materialised
4 Yesterday's strong names washing out + AI failing to catch the baton = double kill Did not materialise: baijiu +0.63% and banks −0.77% amount to a mild washout; AI applications caught the baton in a big way Did not materialise
5 Dragon-Tiger direction diverges again ⚠️ The 7/31 Dragon-Tiger list was not obtained, so this cannot be judged directly. But industry main-force flows gave isomorphic and even stronger evidence: semiconductors +4.23% yet net outflow of RMB 20.502 billion, components +4.33% yet net outflow of RMB 7.289 billion"price up, money out" holds at the sector level Materialised on a substitute basis ⚠️
6 The Apple chain weakens on its own Did not materialise: consumer electronics +3.49%, 东山精密 +5.98% Did not materialise
7 Month-end last-trading-day money behaviour; low extrapolability of a single-day conclusion Warning valid (today is the last trading day of July, and the pattern was "gap up, run higher, then fade") Warning valid
8 The PMI could change the tape if released as usual Data landed: 49.2%, −1.1 m/m; the market ignored it entirely and indices gapped up and ran higher (see Section 1.4) Direction of the warning was wrong, but logging it as unconfirmed was right
9 Deteriorating cloud-vendor FCF could shift the pricing focus from "who benefits" to "who is burning cash" No such shift observed today Did not materialise
10 Geopolitics and FX No reliable data obtained today Cannot be judged

⭐ The Section 8.1 signal that "takes priority over the A-share auction" (look at Korean and Taiwanese equities first): pre-market wrote "if Korean/Taiwanese semiconductors gap up and fade, then the A-share gap-up at 09:25 is very likely the high of the day". This report did not obtain today's intraday data for Korean/Taiwanese semiconductors and cannot verify whether that signal gave an advance warning — but the A-share outcome was indeed "the gap-up open was the high". This is logged as an outstanding item.

2.7 One-line self-review: which categories were called right, which wrong, and what to change tomorrow morning

Three categories called right (reusable):

  1. The separation of "the news is real but the price has already run ahead" — 永鼎股份 (600105) closed −2.79% on a market-wide broad rally day; this methodology was the sharpest single item on the whole list today.
  2. "Resilience on the way down = no oversold-bounce room" — 紫光国微 (002049) at +0.50% was last within the entire chain; a precise micro call.
  3. The seesaw structure — banks −0.77%, insurance −0.70%, baijiu +0.63% were the worst in the market, strictly inverse to the technology bounce.

Three categories called wrong (must be changed):

  1. ⭐ The most serious: treating "the overnight US-equity mapping" as the sole stock-selection entry point, and therefore being systematically blind to the "domestic AI application line that has nothing to do with overnight US equities". Of the 26 pre-market headlines, only item 23 (ChinaJoy) was AI-application-related, rated C ("weak persistence of sentiment stimulus"). Yet on ChinaJoy's opening day, gaming +4.50%, cultural media +5.28%, film & cinema +4.97%, and 4 limit-ups in the digital media direction, together with a combined net inflow of +RMB 14.494 billion into software development / IT services — this was the real theme of the day, and it did not even have a branch in the pre-market list.
    • What to change tomorrow morning: in the news overview, any exhibition, launch event or opening ceremony actually taking place today/tomorrow must not be given a C rating outright. ChinaJoy and the solar Yancheng meeting were two events held on the same day; pre-market gave solar an A and ChinaJoy a C, and the result was solar +1.83% underperforming the market while media and gaming led the whole market — the ratings were exactly inverted. The criterion should be changed to: "whether the event actually occurs on the day" takes priority over "the industrial hardness of the event", because A-shares price the event window, not the industrial hardness.
  2. ⭐ The second most serious: treating "a gap-up open" as evidence that the news has been digested, rather than as the risk itself. Section 8.1 pre-market turned the size of the gap into a "3%–5% is most balanced" range criterion, but today's fact is that the size of the gap was significantly negatively correlated with the full-day return — 兆易/德明利/风华高科, which all opened +10%, closed +2.02 / −1.06 / −2.28 respectively; 工业富联, which opened +6.21%, closed +5.39%; 紫光股份, which opened +3.87%, closed +3.84%.
    • What to change tomorrow morning: write the empirical rule "for stocks gapping up ≥ 8%, the expected value of the day's close should be revised down, not up" directly into the pre-market list, and make "is the opening price the high of the day" the number-one intraday observation item.
  3. The test for "dual-dimension Pass" is too loose — 太极实业 (600667) and 江海股份 (002484) were 0/2 today. The fundamental falsification (at company-announcement grade) is solid, but it was wrongly extrapolated into "the sentiment dimension is unsupportive too".
    • What to change tomorrow morning: the sentiment-dimension test for a "dual-dimension Pass" must add a hard threshold — any name with a maximum drawdown of more than 40% over the last 30 days may never be judged "sentiment dimension unsupportive" (太极实业 drew down −51.2% from 7/1 to 7/30, 德明利 drew down −60.2%; both are natural fuel for an oversold bounce). A sharp collapse is itself sentiment ammunition, and this is the most expensive lesson of this session.

One more ranking failure to log: the fine-grained rankings made pre-market within branches (packaging & testing: 长电 > 通富 > 华天; AI PCB: 沪电 > 生益 > 深南 > 东山) were almost entirely inverted today — the actual closes were 华天 +3.76 > 长电 +1.86 > 通富 +1.50, and 深南 +8.26 > 沪电 +7.46 > 东山 +5.98 > 生益 +5.56. Conclusion: on an oversold-bounce day, ranking within a branch on one-point differences in "fundamentals / money flow" is useless; pre-market should give only "branch membership" and no within-branch ordering.


3. Verification of today's leading theme

Branch Pre-market strength Actual performance today (THS industry basis) Limit-up tier structure Stage Conclusion
⭐ Domestic AI applications / software / media (completely missed pre-market) Not included in any branch (only item 23, ChinaJoy, rated C) IT services +6.29% (126 up, 3 down, net inflow +RMB 5.465 billion), software development +6.15% (138 up, 0 down, net inflow +RMB 9.029 billion), cultural media +5.28% (78 up, 5 down, +RMB 4.795 billion), film & cinema +4.97%, computer equipment +4.60% (+RMB 2.615 billion), gaming +4.50% (+RMB 2.342 billion), communication services +4.47% (+RMB 1.901 billion) — taking 7 of the top 8 places on the gainers board and sweeping the top three of the net-inflow board Complete tier structure: 20cm limit-ups — 蓝色光标 (BlueFocus, 300058; limit bid queue RMB 1.543 billion, turnover RMB 8.553 billion), 昆仑万维 (Kunlun Tech, 300418; turnover RMB 6.066 billion), 中文在线 (Chinese Online, 300364), 易点天下 (Yidiantianxia, 301171), 普联软件 (Pulian Software, 300996; 2 consecutive); 10cm limit-ups — 用友网络 (Yonyou Network, 600588), 泛微网络 (Weaver Network, 603039; 2 consecutive), 税友股份 (Servyou Group, 603171; 2 consecutive), 美利云 (Meili Cloud, 000815), 天娱数科 (Tianyu Digital, 002354), 浙文互联 (Zhewen Interactive, 600986), 智度股份 (Zhidu Technology, 000676), 风语筑 (Fengyuzhu, 603466); plus 深信服 (Sangfor Technologies, 300454) +14.78% Launch / day 1 ⚠️ The core object of observation tomorrow. "Launch day + top net inflow + complete tier structure" are three positives; but "day 1" means it has not yet been through any divergence test
AI hardware oversold bounce (pre-market branch #1) A+ Semiconductors +4.23% (175 up, 8 down, but net outflow of −RMB 20.502 billion, the largest in the market), components +4.33% (57 up, 5 down, net outflow −RMB 7.289 billion, the second largest), communication equipment +3.98% (+RMB 722 million). Sub-branch differences are extreme: AI PCB average +6.68% (strongest) > optical modules +3.67% > servers/compute +3.37% > packaging & testing +1.98% (weakest) ⚠️ The limit-up tier structure is essentially nil: not a single main-board name in the entire chain held a limit-up (沪电, 生益, 深南, 东山 and 光迅 all touched the limit intraday and then broke it); in the limit-up-break pool, components with 15 names and semiconductors with 8 led the field Day 1 of the oversold bounce, and clear divergence has already appeared ⚠️ Divergence (leaning towards no continuation). Reason: index-level gains + fund-level outflows + zero limit-ups + the highest break rate, all four appearing at once. The pre-market characterisation that "this is a bounce within a downtrend, not a reversal" was fully confirmed today
Memory price hikes (pre-market branch #2, S-rated) S 兆易创新 (603986) one-line limit-up opened → closed +2.02%, 德明利 (001309) one-line limit-up opened → closed −1.06%, 普冉股份 (688766) opened +20.00% → closed +0.50%, 江波龙 (Longsys, 301308) +2.42%, 佰维存储 (Biwin Storage, 688525) +2.80%, 澜起科技 (Montage Technology, 688008) +4.13%, 北京君正 (Ingenic Semiconductor, 300223) +2.55%, 长鑫科技 (CXMT, 688825) +2.08% (opened +10.08%, intraday high +14.62%, turnover RMB 50.337 billion); the memory chain averaged only +2.77%, underperforming the all-A median Only one main-board limit-up, 太极实业 (600667), and it is the one pre-market Passed Divergence on the very day of the climax (one-line limit-ups across the board in the morning → breaks across the board in the afternoon) ⚠️ The highest washout risk of all. One-line limit-ups at the open across the chain, breaks at the close across the chain — the most textbook "one-day-wonder cash-out" pattern. The counter-evidence flagged pre-market — "TrendForce Q3 DRAM contract prices up only +13%~18% q/q versus about +60% in Q2, a sharply converging price-hike slope" — remains valid
Solar "anti-involution" (pre-market branch #3) A Solar equipment +1.83% (60 up, 9 down), underperforming the all-A median of 2.03% and ranking 52nd of 90 industries; 通威股份 (600438) −0.09%, 隆基绿能 (601012) −0.23%, 福莱特 (Flat Glass, 601865) +0.90%, 协鑫集成 (GCL System Integration, 002506) +2.01%, 弘元绿能 (603185) +4.62% No main-board limit-up; still the continuation of "弘元绿能 as a lone name" Washout / event ineffective ❌ Complete non-delivery. Today's Yancheng price-compliance guidance meeting was held, but the substantive increment on the tape was zero. The pre-market qualifier that "it is price-compliance guidance, not production curbs and not a price increase" was right, but if so it should never have been ranked among the top 3 branches
Politburo meeting mapping (one of the pre-market top-3 branches) A Grid equipment +2.05% (net outflow RMB 231 million), real estate +1.60%, brokers +0.25% (net outflow RMB 1.367 billion, 6th from the bottom), banks −0.77% (worst) 香江控股 (600162) 2 consecutive limit-ups; 广电电气 (601616) −3.68%, streak broken Washout ❌ On the "first full trading day" after the Politburo meeting, all five mapped directions underperformed the market. The strong counter-evidence given pre-market (grid equipment −2.46% for the whole day on 7/30 with net outflow of RMB 2.664 billion) remains valid today
Baijiu / mass consumption (pre-market branch #5, already downgraded to B+) B+ Baijiu +0.63% (14 up, 5 down), beverage manufacturing +2.00%, food processing +1.51% None Mild washout The pre-market question "today is a falsification day" got the direction right: baijiu indeed could not outperform during a technology bounce, but it did not collapse either
Banks / insurance (pre-market branch #6) B Banks −0.77% (9 up, 32 down, worst in the market), insurance −0.70% (1 up, 4 down, second worst) None Washout The seesaw criterion held completely
Passive components / MLCC (pre-market branch #8) B 风华高科 (000636) opened +10.00% → closed −2.28%; 三环集团 (Chaozhou Three-Circle, 300408) +6.06%; 江海股份 (002484) +5.78% (dual-dimension Pass pre-market) None Attempted one-day wonder, failed ⚠️ The day before the 8/1 price increase takes effect, the leader ended with "one-line limit-up opened → turned red"
Gold / precious metals (pre-market judged "does not constitute a sector") B (A at the stock level, C at the sector level) Precious metals +4.00% (14 up, 0 down, net inflow +RMB 1.453 billion), 招金黄金 (000506) at limit-up 招金黄金, 1 limit-up (26 limit-up breaks) Launch ⚠️ A sector-level rise did occur (see the side-by-side note in Section 2.4)

3.1 Did pre-market identify the strongest theme: no

The pre-market ranking of the top 3 branches was: ① AI hardware oversold bounce ② memory price hikes ③ solar anti-involution.

Today's actual top 10 industries by gain (THS, 90 industries):

Rank Industry Change % Net inflow (RMB 100 million) Advancers / decliners Covered pre-market?
1 IT services +6.29% +54.65 126 / 3 ❌ Not covered
2 Software development +6.15% +90.29 138 / 0 ❌ Not covered
3 Automation equipment +5.34% +14.53 94 / 2 ❌ Not covered
4 Cultural media +5.28% +47.95 78 / 5 ❌ Only C-rated ChinaJoy
5 Film & cinema +4.97% +11.81 20 / 0 ❌ Not covered
6 Computer equipment +4.60% +26.15 82 / 0 ❌ Not covered
7 Gaming +4.50% +23.42 23 / 1 ❌ Only C-rated ChinaJoy
8 Communication services +4.47% +19.01 38 / 6 ❌ Not covered
9 Components +4.33% −72.89 57 / 5 ✅ Branch 1
10 Semiconductors +4.23% −205.02 175 / 8 ✅ Branches 1 and 2

Conclusion: the pre-market list covered none of the top 8 gainers; the branches it pushed hardest ranked 9th and 10th, and were the two sectors with the largest net outflows in the market.

3.2 Unexpected themes missed pre-market (3 items)

  1. ⭐ Domestic AI applications / large models / media and gaming — the real theme of the day. At least three attributable public catalysts exist: ① ChinaJoy 2026 opened in Shanghai today (7/31) under the theme "Journey with AI", with more than 500 exhibitors and over a thousand titles (this was written pre-market, but rated C); ② Hong Kong-listed large-model names rose in tandem, with 智谱 (Zhipu AI) +20.53% and 迈富时 (Marketingforce) up more than 20%; ③ compute-leasing names rallied collectively, with 利通电子 (Litong Electronic, 603629), 美利云 (000815), 盈峰环境 (Infore Environment, 000967) and 证通电子 (Zhengtong Electronics, 002197) at limit-up, and 深信服 (300454) +14.78%. ⚠️ On the specific attribution of 蓝色光标 (300058)'s limit-up, this report has obtained only after-the-fact analysis from brokers/media (AI + overseas expansion strategy, AI-related revenue of over RMB 3.7 billion in 2025, overseas revenue of over RMB 56.4 billion), and has not obtained the company's original announcement today, so none of those figures is cited as factual evidence.
  2. Automation equipment +5.34% (net inflow +RMB 1.453 billion) — 绿的谐波 (Leaderdrive, 688017) +16.34%, 雷赛智能 (Leadshine Technology, 002979) at limit-up. Directionally consistent with the event window of "宇树科技 (Unitree Robotics) price consultation on 8/5 and subscription on 8/10", but this report has obtained no evidence directly linking today's rise to the Unitree IPO, so no causal attribution is made; it is logged only as a direction to verify tomorrow morning.
  3. Precious metals +4.00% (14 up, 0 down) — see the side-by-side note in Section 2.4.

4. Limit-up tier structure / high-streak names

4.1 High streaks and consecutive limit-up structure

Streak Count Stocks
9 consecutive 1 爱丽家居 (Aili Home Furnishings, 603221), +10.00%, turnover RMB 451 million, turnover rate 8.25%, 0 limit-up breaks (an earnings-dimension Pass pre-market, which explicitly wrote "not claiming it will not rise today")
5 consecutive 1 传智教育 (Chuanzhi Education, 003032), +9.99%, turnover RMB 360 million, turnover rate 14.52%, 1 limit-up break (AI applications / education)
4 consecutive 1 一鸣食品 (Yiming Foods, 605179), +9.99%, turnover RMB 397 million (beverages & dairy)
3 consecutive 1 高争民爆 (Gaozheng Explosive, 002827), +10.02%, turnover RMB 761 million, 3 limit-up breaks (chemical products)
2 consecutive 6 普联软件 (Pulian Software, 300996) (+19.97%, turnover RMB 1.192 billion, turnover rate 20.65%, software development), 泛微网络 (Weaver Network, 603039) (+9.99%, turnover RMB 860 million, software development), 税友股份 (Servyou Group, 603171) (+10.01%, turnover RMB 962 million, IT services), 香江控股 (600162) (+10.03%, 8 limit-up breaks, real estate), 中国宝安 (China Baoan, 000009) (+10.07%, turnover RMB 1.105 billion, 7 limit-up breaks), 神雾节能 (000820) (+10.00%, turnover only RMB 28 million)
First limit-up 89

⚠️ The core feature of the consecutive-limit-up structure: 3 of the 6 names in the 2-consecutive tier (普联软件, 泛微网络, 税友股份) belong to software / IT services — the new theme has already secured position at the most critical relay slot, "the 2nd consecutive limit-up", and this is the first thing to watch in judging whether AI applications can continue tomorrow. Meanwhile the high-streak names at 3–9 consecutive (高争民爆, 一鸣食品, 传智教育, 爱丽家居) have nothing to do with today's theme and are independent sentiment high-streak names.

4.2 Follow-through rate (performance today of the 52 limit-up names from 7/30)

  • 31 up / 20 down / 1 flat, average gain +2.85% (slightly above the all-A median of 2.03%).
  • 10 hit limit-up again today, a follow-through rate of 19.2%: 普联软件 (300996) +19.97, 中国宝安 (000009) +10.07, 香江控股 (600162) +10.03, 高争民爆 (002827) +10.02, 税友股份 (603171) +10.01, 爱丽家居 (603221) +10.00, 神雾节能 (000820) +10.00, 一鸣食品 (605179) +9.99, 泛微网络 (603039) +9.99, 传智教育 (003032) +9.99.
  • ⚠️ On a huge broad-rally day with 99 limit-ups, 0 limit-downs and 4690 advancers, the follow-through rate of yesterday's limit-up names was only 19.2% with 20 of them falling — which says today's money was "rotating into a new direction" rather than "relaying yesterday". This point matters a great deal for tomorrow's judgement.

4.3 Core names (large turnover + high recognisability)

Stock Change % Turnover Role
蓝色光标 (BlueFocus, 300058) +19.98% (20cm limit-up) RMB 8.553 billion The most recognisable name in the market today, limit bid queue RMB 1.543 billion, turnover rate 18.17%, 1 limit-up break. The pricing anchor of the new theme (AI applications)
太极实业 (Taiji Industry, 600667) +10.03% (limit-up) RMB 6.338 billion The largest turnover among today's 87 main-board limit-up stocks, turnover rate 17.66%, 4 limit-up breaks. The one Passed pre-market
昆仑万维 (Kunlun Tech, 300418) +20.00% (20cm limit-up) RMB 6.066 billion Re-sealed the limit after 17 limit-up breaks, AI large-model direction
深信服 (Sangfor, 300454) +14.78% RMB 5.037 billion Touched the 20cm limit intraday then broke it; compute leasing / software
利欧股份 (Leo Group, 002131) +10.00% (limit-up) RMB 3.762 billion 2nd largest turnover among main-board limit-ups; advertising & marketing / AI applications
麦格米特 (Megmeet, 002851) +10.00% (limit-up) RMB 3.107 billion Most limit-up breaks in the market: 28, other power supplies
兆易创新 (GigaDevice, 603986) +2.02% RMB 34.043 billion ⚠️ The 2nd largest turnover in the market, yet up only 2.02% — the most textbook sample of "huge volume, stalled price"
中际旭创 (Innolight, 300308) +4.40% RMB 54.044 billion ⚠️ The largest turnover in all-A (third consecutive day), but its gain lagged three follower names
长鑫科技 (CXMT, 688825) +2.08% RMB 50.337 billion ⚠️ Opened +10.08%, high +14.62%, closed +2.08%. The memory chain's pricing anchor gave back more than 12 percentage points, the heaviest single piece of negative evidence for the memory chain today

4.4 Broken streaks and limit-up breaks

  • 107 limit-up breaks, a break rate of 51.9%, the highest of the week (the 7/27 climax day was only 10.5%).
  • Leading industries in the limit-up-break pool: components 15, semiconductors 8, auto parts 7, plastics 5, automation equipment 5, software development 5the heaviest breakage was precisely in the chain pushed hardest pre-market.
  • The 5 largest-turnover names in the limit-up-break pool are all names called out pre-market: 兆易创新 (603986) RMB 34.043 billion, 东山精密 (002384) RMB 21.468 billion, 德明利 (001309) RMB 17.355 billion, 中国巨石 (China Jushi, 600176) RMB 15.803 billion, 风华高科 (000636) RMB 13.582 billion.
  • Broken streaks (limit-up yesterday, down today): 20 names; the worst 5: 恒尚节能 (Hengshang Energy Saving, 603137) −4.62%, 广电电气 (601616) −3.68%, 新芝生物 (Xinzhi Biotechnology, 920685) −3.44%, 陆家嘴 (600663) −3.02%, 和泰机电 (Hetai Electromechanical, 001225) −2.82%. Among them 广电电气 and 陆家嘴 were pre-market Pass / watch-only names, so those calls were right.
  • Distribution of first limit-up seal times: call auction–9:30 6 names, 9:30–10:00 45 names, 10:00–11:00 29 names, 11:00–13:00 7 names, 13:00–14:30 11 names, 14:30–close 1 name. 74.7% of limit-ups occurred before 11am, with almost no new seals in the afternoon — completely consistent with the indices' "gap up then fade" pattern, further showing that today was a "single morning wave".

5. Fund flows

5.1 ⭐ Today's most important fund-flow fact: the theme rotation is more complete in money terms than in price terms

Top 6 net inflows (THS industry basis, RMB 100 million)

Industry Change % Net inflow Advancers / decliners
Software development +6.15% +90.29 138 / 0
IT services +6.29% +54.65 126 / 3
Cultural media +5.28% +47.95 78 / 5
Auto parts +2.70% +27.10 245 / 24
Computer equipment +4.60% +26.15 82 / 0
General equipment +3.68% +24.13 238 / 13

Top 6 net outflows (same basis)

Industry Change % Net inflow Advancers / decliners
Semiconductors +4.23% −205.02 175 / 8
Components +4.33% −72.89 57 / 5
Construction & decoration +2.83% −37.54 128 / 13
Batteries +1.66% −19.73 78 / 27
Electronic chemicals +3.41% −16.10 40 / 3
Brokers +0.25% −13.67 35 / 12

⭐ This comparison table is the single most valuable item in everything today:

  • Semiconductors and components ranked 9th and 10th on the gainers board and simultaneously 1st and 2nd on the net-outflow board. Combined net outflow of RMB 27.791 billion.
  • Software development, IT services and cultural media ranked 1st, 2nd and 4th on the gainers board and simultaneously 1st, 2nd and 3rd on the net-inflow board. Combined net inflow of RMB 19.289 billion.
  • One side is "rising while money leaves", the other is "rising while money arrives". Judged only on price change these two lines both look strong (both up 4%–6%), but on the money dimension they are exact opposites.
  • ⚠️ Basis reminder: the THS "net inflow" is a main-force fund basis (a net figure computed by stratifying individual trade sizes) and is not equal to true market-wide fund flow, nor can it be mixed with the Dragon-Tiger or northbound bases; semiconductor turnover for the day was RMB 458.373 billion, so the RMB 20.502 billion net outflow is about 4.5% of it — a medium-strength signal, not decisive evidence, but it points the same way as three independent pieces of evidence (zero limit-ups + a 51.9% break rate + huge volume with a stalled price), and it is the four together that constitute this report's judgement.

5.2 Northbound flows: no reliable data available (third consecutive day)

  • stock_hsgt_fund_flow_summary_em returns 0.000 for the "net buy turnover" of both the Shanghai Connect and Shenzhen Connect northbound records. As stated in disclosure item 4, this is a null value from the interface after the exchanges discontinued single-day net-buy disclosure from August 2024; it is not "net buying of zero". This report does not use that figure, writes "no reliable data available", and makes no speculation.
  • The part of that interface that is still valid and usable — the advance/decline counts of northbound-eligible names: Shanghai Connect 1245 up / 52 flat / 343 down; Shenzhen Connect 1582 up / 36 flat / 257 down. This can only describe breadth within the northbound-eligible pool and cannot be used to infer money direction.
  • Southbound (usable): Stock Connect (Shanghai) net buying +RMB 1.297 billion, Stock Connect (Shenzhen) −RMB 185 million, with the day's fund balance at RMB 42 billion for both; the Hang Seng Index −0.03% (same interface basis).

5.3 Dragon-Tiger list: not obtained today, logged as an outstanding item

  • stock_lhb_detail_em(start_date=20260731, end_date=20260731) returned an empty object at 15:40 (TypeError: 'NoneType' object is not subscriptable). Exchange Dragon-Tiger lists are usually published around 18:00 after the close, so this report's cut-off is earlier than the publication time.
  • Therefore this report cites no 7/31 Dragon-Tiger figures anywhere. In particular, the following directions — the most worth checking today — are all marked "cannot be confirmed at this time":
    1. The nature of the buy/sell seats behind 太极实业 (600667)'s limit-up (retail speculators, institutions, or Shanghai Connect) — this is the single most critical piece of information for judging tomorrow morning whether it can post a 2nd consecutive limit-up;
    2. The seat structure behind the two 20cm limit-up leaders 蓝色光标 (300058) and 昆仑万维 (300418);
    3. The net buy/sell direction of 兆易创新 (603986) and 德明利 (001309) during their "one-line limit-up opened → break" process — both were net-sell samples on the Dragon-Tiger list yesterday, and today's direction could directly confirm or refute the judgement that "money is leaving the memory chain";
    4. Whether the money behind 长电科技 (600584)'s +RMB 317 million of net buying from the fifth-largest buy seat yesterday added or exited today.
  • ⚠️ This is the same kind of outstanding item as yesterday's recap logging "the 7/30 Dragon-Tiger list was not obtained" (which was filled in and cleared in this morning's pre-market list). It is logged again this time, and tomorrow morning's pre-market list must fill it in.

5.4 Summary of sectors leading main-force net inflows

Net inflows are highly concentrated in two lines, "domestic AI applications + broad manufacturing equipment": software development +9.029, IT services +5.465, cultural media +4.795, auto parts +2.710, computer equipment +2.615, general equipment +2.413, gaming +2.342, industrial metals +2.306, communication services +1.901, white goods +1.537, precious metals +1.453, automation equipment +1.453 (RMB billion).

Net outflows are highly concentrated in "AI hardware + procyclical financials": semiconductors −20.502, components −7.289, construction & decoration −3.754, batteries −1.973, electronic chemicals −1.610, brokers −1.367, energy metals −1.097, consumer electronics −1.083 (RMB billion).


6. Outlook for the next session (Monday, August 3)

⚠️ Qualifier up front: today is the last trading day of July, so month-end ranking and portfolio-rebalancing behaviour is present; the next trading day is the Monday after the month turn, separated by two calendar days and a full weekend (overseas markets — US equities on 7/31 and Asia-Pacific on 8/1 — will by then constitute new external variables; none of these had happened as of this report's cut-off, and no prediction is made). Today's single-day conclusions are therefore less extrapolable than usual, and the confidence of the judgements below should be discounted accordingly.

6.1 Theme-continuation judgements

Theme Status today Judgement for tomorrow Basis
Domestic AI applications / software / media Day 1 of launch, top net inflow, complete tier structure, 3 names already at 2 consecutive limit-ups ⚠️ Wait for divergence (do not chase first limit-ups; watch for the 2nd consecutive) Positive: first on both money and price, software development 138 up and 0 down with not a single decliner, the 2-consecutive slot already taken. Negative: everything is a first or 2nd limit-up and has not been through any divergence test; the 20cm names (蓝色光标, 昆仑万维) carry a high cost of consecutive limit-ups; ChinaJoy runs 7/31–8/3, so Monday is the last day of the show — the event window is about to close, not open
AI hardware (packaging & testing / PCB / servers / optical modules) Index up, money out, zero limit-ups, most limit-up breaks ⚠️ Divergence leaning washout, with AI PCB the single exception Four points against continuation: semiconductor net outflow of RMB 20.502 billion and component net outflow of RMB 7.289 billion; zero limit-ups across the entire main-board chain; components + semiconductors account for 23 names in the limit-up-break pool; 兆易创新 rose only 2.02% on RMB 34 billion of turnover. Two points supporting AI PCB as an exception: the four AI PCB names all closed green with an average of +6.68%, the strongest in the chain (the only pre-market criterion, item 4, that held); 深南电路 +8.26% and 沪电股份 +7.46% were the two strongest closes in the entire chain
Memory price hikes One-line limit-ups across the chain at the open → breaks across the chain at the close ⚠️ Highest washout risk 长鑫科技 (688825) as the pricing anchor gave back 12 percentage points; all three one-line limit-ups — 兆易创新, 德明利, 普冉股份 — were broken, with 德明利 closing red; the only one that held, 太极实业 (600667), depends on a narrative that directly contradicts the company's own announcement and that this report could not verify
Solar anti-involution The sector underperformed the market on the day of the meeting Washout / remove The event has landed with no substantive increment; recommend that tomorrow morning's pre-market list no longer include it as a branch
Politburo meeting mapping (grid / property / brokers / banks) All five directions underperformed Washout Rejected by the tape on two consecutive trading days
Baijiu / banks (defensive line) Mild washout, worst in the market Seesaw continues: if technology continues they stay weak; if technology cracks they are where the money goes

6.2 Key focus for tomorrow (branches + main-board names + verification points)

Stated again: the following is a ranking of research attention and observable verification conditions, and contains no buy/sell recommendations, position sizing, target prices or ratings.

Priority Direction Main-board names (note: the highly recognisable names in the new theme are concentrated on ChiNext, so the main-board candidates are inherently weaker — this is tomorrow's structural difficulty) Verification points for tomorrow
1 The "2nd consecutive limit-up" in AI applications / software / IT services 用友网络 (Yonyou Network, 600588) (+10.03% today, turnover RMB 1.036 billion, 0 limit-up breaks, Shanghai main board), 泛微网络 (603039) (2 consecutive today, turnover RMB 860 million), 税友股份 (603171) (2 consecutive today, turnover RMB 962 million), 浙文互联 (600986) (+10.00%, turnover RMB 1.115 billion), 智度股份 (000676) (+10.00%, turnover RMB 1.020 billion), 美利云 (000815) (+10.00%, compute leasing) ① Can at least 2 of the three 2-consecutive names — 泛微网络, 税友股份, 普联软件 (300996) — reach a 3rd consecutive limit-up? This is the only hard criterion for whether the new theme is established; ② can the net inflow into the three industries of software development + IT services + cultural media stay positive for a 2nd consecutive day? (combined +RMB 19.289 billion today); ③ can 蓝色光标 (300058), as the pricing anchor, gap up without breaking the limit? (limit bid queue RMB 1.543 billion today). If fewer than 2 of the three hold, today was a one-day wonder
2 AI PCB (the only sub-branch of AI hardware not yet falsified) 深南电路 (002916) (+8.26% today, strongest in the chain, 13 limit-up breaks), 沪电股份 (002463) (+7.46% today, pre-market fundamentals 12.5/15, highest on the list), 生益科技 (600183) (+5.56%), 东山精密 (002384) (+5.98%, turnover RMB 21.468 billion, largest on the main board) ① Can all four close green together for a 2nd consecutive day? (this condition held today and was the only branch criterion from pre-market to hold in full); ② can the components sector's net flow turn positive from today's −RMB 7.289 billion?this matters more than the price change; ③ can the first genuinely sealed limit-up appear among the four? (today all of them touched the limit intraday and then broke it)
3 紫光股份 (Unisplendour, 000938) — listed separately 紫光股份 (000938) (today opened +3.87 / closed +3.84, turnover expanded from RMB 8.755 billion to RMB 14.167 billion) It is the only large cap on the entire list today that did not gap up and dive (its opening and closing gains are almost identical), and on a day of "the open was the high" that is a scarce pattern. Verification point: can it continue rising on expanded volume tomorrow without relying on a gap-up?
4 工业富联 (601138) — retained as the "authenticity discriminator" 工业富联 (601138) (+5.39% today, closing stronger than all the oversold names) This discriminator designed pre-market gave a valid signal today, so keeping it is recommended: if it continues to be stronger than 长电/通富/兆易 tomorrow, money really is concentrating on the end with solid fundamentals; if it weakens, AI hardware as a whole is downgraded

6.3 Avoid / downgrade for tomorrow

Direction Reason
⚠️ Chasing the memory chain higher (兆易创新 603986, 德明利 001309, 太极实业 600667, 深科技 000021) A one-line limit-up at the open → a break at the close is the most textbook one-day-wonder cash-out pattern; 德明利's "watch closely" tag is already void under the rule pre-market set for itself; 兆易创新 rose only 2.02% on RMB 34.043 billion of turnover; 长鑫科技 (688825), the pricing anchor, gave back 12 percentage points over the day
⚠️ 太极实业 (600667) singled out as the highest risk ① The narrative underpinning today's rise — "海太 receives additional investment from SK Hynix / HBM3E packaging & testing" — was obtained by this report only from self-media and aggregator sources, with no original company announcement, and directly contradicts the company's 2026-06-26 Interim 2026-039 announcement stating it "does not involve HBM products"; ② it broke the limit 4 times over the day; ③ its Dragon-Tiger data for today cannot be confirmed at this time; ④ the East Money limit-up pool classifies it under "engineering consulting" rather than semiconductors — fully consistent with the pre-market finding that "94% of profit comes from 十一科技 (engineering design)". Until a company announcement appears, this report's fundamental falsification conclusion stands unchanged, while explicitly acknowledging that its price judgement on this name was wrong today
⚠️ The three packaging & testing leaders (长电 600584, 通富 002156, 华天 002185) The pre-market "single most important sector criterion" went 0/3 today; 长电's opening price was the high of the day, with rising volume and no price gain; their branch status should not be restored until that criterion holds again
High-level sentiment lone names (爱丽家居 603221 already at 9 consecutive, 传智教育 003032 at 5, 一鸣食品 605179 at 4, 高争民爆 002827 at 3) None of them relate to today's theme; 爱丽家居's turnover was only RMB 451 million with a turnover rate of 8.25%, so the risk is not whether it rises, but being unable to sell once the limit opens (carried over from the pre-market judgement, still valid today)
Solar (通威 600438, 隆基 601012), grid equipment (海兴电力 603556), property (陆家嘴 600663, 香江控股 600162), brokers (中信证券 CITIC Securities, 600030) The policy-mapping directions have been rejected by the tape on two consecutive days; the substantive increment from today's meeting was zero
永鼎股份 (600105) The pre-market judgement that "the price has already run ahead of the news" was fully confirmed today (closed −2.79% on a broad rally day), conclusion maintained
风华高科 (000636) and the "8/1 price increase takes effect" MLCC mapping The day before it takes effect ended with "one-line limit-up opened → closed −2.28%"; the day the good news is delivered is often the day the move ends

6.4 Input prompts for tomorrow morning's pre-market list (each item must be responded to)

  1. ⭐ The outstanding item that must be filled in (highest priority) — the 7/31 Dragon-Tiger list. Published around 18:00 after the close; it must be obtained tomorrow morning with stock_lhb_detail_em(20260731), focusing on the four directions listed in Section 5.3, especially the seat nature behind 太极实业 (600667) and the net buy/sell direction of 兆易创新/德明利 during their limit-up breaks. The same outstanding item from yesterday was cleared this morning; this one must not be deferred again.
  2. ⭐ The branch that must be added — domestic AI applications / software / IT services / media and gaming. Today it took 7 of the top 8 places on the gainers board and all of the top 3 on the net-inflow board, while the pre-market list did not even have a branch for it. Tomorrow morning it must be given its own branch with main-board name coverage, and note one structural difficulty: the highly recognisable names in this theme (蓝色光标 300058, 昆仑万维 300418, 中文在线 300364, 深信服 300454) are almost all on ChiNext, so under the "main board first" rule the main-board candidates are inherently weaker. This must be explained to readers up front rather than padding out a main-board list.
  3. ⭐ The rating rule that must be changedany exhibition, launch event or opening ceremony "actually taking place today/tomorrow" must not be given a C rating outright. Today ChinaJoy (rated C) and the solar Yancheng meeting (rated A) were held on the same day, and the result was media and gaming leading the whole market while solar underperformed it — the ratings were exactly inverted. New criterion: "whether the event actually occurs on the day" should carry more weight than "the industrial hardness of the event".
  4. ⭐ The empirical rule that must be written in — the size of the gap-up is negatively correlated with the day's return. Today's samples: 兆易创新/德明利/风华高科, which opened +10.00%, closed +2.02 / −1.06 / −2.28; 普冉股份 (688766), which opened +20.00%, closed +0.50; 工业富联, which opened +6.21%, closed +5.39%; 紫光股份, which opened +3.87%, closed +3.84%. Tomorrow morning's pre-market list should write in directly that "for stocks gapping up ≥ 8%, the expected value of the day's close is revised down", and make "is the opening price the high of the day" the number-one intraday observation item.
  5. ⭐ The test that must be tightened — the sentiment-dimension threshold for a "dual-dimension Pass". Both dual-dimension Passes today (太极实业 600667, 江海股份 002484) were called wrong. New hard threshold: any name with a maximum drawdown of more than 40% over the last 30 days may never be judged "sentiment dimension unsupportive"; at most it can be judged an "earnings-dimension Pass". (太极实业 drew down −51.2% from 7/1 to 7/30, 德明利 drew down −60.2%.)
  6. The practice that must be dropped — fine-grained ordering within a branch. Today packaging & testing (pre-market 长电>通富>华天, actual 华天>长电>通富) and AI PCB (pre-market 沪电>生益>深南>东山, actual 深南>沪电>东山>生益) were almost entirely inverted. On an oversold-bounce day, give "branch membership" only, not within-branch ordering on one-point differences.
  7. The three effective methodologies that must be retained: ① the price separation of "the news is real ≠ you should chase it" (validated by 永鼎股份 today); ② "resilience on the way down = no oversold-bounce room" (validated by 紫光国微 today); ③ the technology/defensive seesaw (validated by banks and insurance being the worst today).
  8. The fund-flow criterion that must continue to be trackedthe divergence between "sector price change vs sector net inflow". Today's semiconductors +4.23% / −RMB 20.502 billion and components +4.33% / −RMB 7.289 billion were the most important signals in the market. Recommend upgrading this into a fixed section of the pre-market list: for every sector admitted as a branch, the previous day's price change and net inflow must both be listed, and a divergence in direction forces a downgrade.
  9. Two external variables that need to be verified pre-market: ① US equities on 7/31 and Asia-Pacific markets on 8/1 (neither had happened as of this report's cut-off); ② the actual performance of Korean/Taiwanese semiconductors today (7/31) — Section 8.1 pre-market set this as the "signal zero" with "priority over the A-share auction", but this report obtained no data and cannot verify whether that signal gave an advance warning; this is likewise logged as an outstanding item.
  10. Calendar events to be aware of in advance: 宇树科技 (Unitree Robotics) preliminary price consultation on 8/5, online and offline subscription on 8/10, payment on 8/12 (today automation equipment rose +5.34% with net inflow of +RMB 1.453 billion, directionally consistent with that event window, but this report obtained no direct causal evidence, so tomorrow morning it must be handled under the existing rule that "any supply relationship without an announcement behind it is treated as a pure concept mapping"); ChinaJoy runs through 8/3, with Monday the last day.
