There is only one trade today: Saudi crude exports have recovered (back above 4 million bpd in September, versus a low of just 2.4 million bpd in August), and WTI fell for a 4th consecutive session to…
The hardest fact today is not a headline, it is a spread that can be computed within one and the same timestamp and one and the same currency: on 9/17 the A-share market killed precious-metal equities…
Today was risk-on, but not the kind of risk-on this morning's pre-market watchlist described — the leader was not its No. 1 theme, it was its No. 3 theme. S&P +1.14%, Nasdaq +1.69%, Dow +0.61%, Russel…
Yesterday the Fed hiked because of oil, and today oil collapsed on its own — that is the one-sentence explanation for this entire morning. The Fed hiked 25bp to 3.75%–4.00% at 09-16 14:00 ET, 12-0 una…
Sentiment turned from euphoric to receding; the pre-market list got the leading theme wrong — and also got wrong the one bearish call it was most confident about. Today the Shanghai Composite fell −0.…
The chronology is real, but the conclusions drawn from it must be discounted. The broad A-share rally on 9/16 (75.1% of names up, semiconductors 184 up / 1 down) did all happen before the FOMC release…
The hike itself was fully expected; what knocked the market down was the dot plot and the language — the pre-market piece got "the real variable is not this 25bp but the dot plot and Warsh's language"…
There is only one real protagonist in this pre-market, and it does not come on stage until two in the afternoon. The FOMC decision at 14:00 ET and the press conference by Powell's successor Kevin Wars…
Sentiment jumped straight from "freezing point" to "broad-based euphoria": limit-ups 32 → 89, limit-downs 27 → 4, failed-limit rate 42.9% → 11.0%, promotion rate 13.0% → 37.5%, gap-up hold rate 17.4% …
Today is a "no new catalyst day." Filings inside the window were dominated by the "abnormal share-trading fluctuation" category (20-odd of them), and that category was empirically proven just yesterda…
Today was risk-off, but the real axis wasn't AI — it was crude oil. All three major indices turned from green to red: S&P −0.45% (7,585.73), Dow −0.63% (52,093.11), Nasdaq −0.78% (25,981.57), Russell …
Today's pre-market is not a directional trade; it is a "Monday reversal." S&P futures −0.17%, Nasdaq futures −0.12%, SPY −0.14% — at the index level almost nothing moved; but the cross-section underne…
Sentiment temperature: breadth is at freezing point, money is in single-point euphoria. Market-wide 1,120 up / 4,376 down (advancers only 20.2%), mean change −1.37%, median −1.50% — a textbook broad-d…
The strongest catalyst is a "narrative event," not an order event: Anthropic CEO Dario Amodei published an approximately 3,900-word essay "We Must Pace the Frontier" on 9/12 (Sat), arguing that "we mu…
Was today risk-off or risk-on? Neither — it was an extreme rotation inside the market. The S&P 500 fell −0.48% to 7,619.98, but constituents were 281 up / 219 down, the median was +0.27%, and equal-we…
Strongest catalyst: Anthropic CEO Dario Amodei published "We Must Pace the Frontier" on 9/12 (Saturday), arguing for slowing the advance of frontier AI capability; Altman and Musk echoed him the same …
The only S-grade event in the window is a negative: China State Shipbuilding (600150) announced at 00:30 today that a cargo-ship fire broke out at 11:15 on 9/10 at its controlled subsidiary CSSC Qingd…
Today was risk-off, and specifically a day where the pre-market brief "got oil right and energy equities wrong." WTI settled at $102.48 (+6.7%) and Brent at $107.63 (+5.9%), both the highest closes si…
Every asset today sits on the same causal chain, and the chain starts at the Strait of Hormuz. The U.S. military destroyed 5 Iranian oil tankers on 9/8 and the Houthis struck Saudi Arabia's Jazan refi…
Sentiment is "day 3 of the ebb" rather than a turning point: the limit-up count stepped down for a 4th straight day (93 → 73 → 48 → 35), the failed-limit-up rate rose to 38.6%, limit-downs went from 7…
