Short-Term Momentum — the one-week-less-one-day sort — has been reverting for three months, and today it re-asserted hard. The 20-day z sits at -2.77 and the 63-day z at -3.46, with cumulative returns of -3.80% over 20 sessions and -8.81% over 60. One-Day Momentum agreed at the faster lookback, -0.45% at z=-1.58: whatever moved yesterday and whatever moved last week both gave ground today.

The shape matters as much as the sign. The top bucket by recent multi-day performance returned -1.7% and the bottom bucket +0.9%, and the slope between them was near-perfectly ordered — this ran through the whole cross-section, not through a handful of extreme names. Short-covering is ruled out: the most heavily shorted cohort underperformed again at -0.12%, the model's most persistent drag doing its usual work.

Where It Landed: The Metals Complex

The names at the recent-winner end were precious metals. Gold miners in that bucket fell -3.81% as a group, and the Gold factor's own top-exposure decile lost -1.22%. Agnico Eagle (AEM) fell -4.36%, Southern Copper (SCCO) -2.72% and BHP -2.39%, dragging Materials to -0.63%. Against a 20-day Gold factor gain of +3.93%, today's z=-1.59 is one session against a month of one-way payoff.

The macro leg is consistent without doing all the work. July PCE printed at 3.7% year-over-year and pushed September rate-hike odds to 40.1%Economic Times, the dollar index bounced off a fresh 52-week low of 98.90 to close at 99.15, up +0.25%CNBC, and Iran restarted talks with Oman over the Strait of HormuzEconomic Times. Rate-sensitive equity took the other side of the same story: the 10-year at 4.649% and the five-year up 1.6 basis pointsCNBC came with Real Estate as the worst sector at -0.86%, American Tower -1.58% and Welltower -1.93%. But uranium held its ground — URA was higher on four times the typical session pace after a +23.59% twenty-day runBloomberg. A hot recent run was not, by itself, a sentence.

Semis Paid, the Semis ETF Didn't

Semiconductor exposure was the best-paying thematic axis at +0.66%, z=+1.09, with the highest-exposure bucket up +0.9%. SMH ended the session at -0.10%. The gap is one name: Nvidia closed -1.55% into its post-close reportBloomberg, erasing $72.4B of market value, and its weight is what kept the cap-weighted fund flat while the rest of the chip complex worked.

The Session Was Single Names; The Night Is Software

Eighty-three percent of today's cross-sectional variance was idiosyncratic and the index leg explained essentially none of it — realized correlation ran at roughly zero for the session, the 0.8th percentile since 2020. Abercrombie & Fitch closed +36.67% on a Q2 beat that included a $100 million tariff refundBloomberg; Dycom closed -11.61% after its pre-open print, taking $1.2B off its market value. Then the bell rang and the software tape opened up: Okta closed +2.32% and rose a further +13.49% in late trading on a beat-and-raisethe SEC, CrowdStrike added +9.32% after its own results, and Salesforce — flat at -0.03% through the session — jumped +9.20% after hours with no driver yet in the coverage. IGV gained +0.58% in the session and +3.58% after it. None of that touched today's factor returns; it prices tomorrow.

What the Fade Is Not

This was not risk reduction. The model universe was up +0.06% on the session, the top 50 high-beta momentum names were flat at -0.05% against +0.16% for everything else, and implied index volatility eased to 15.31. Hedge-fund-owned names were untouched on both the residualized and raw measures. And the five-day z of +0.25 says this pattern had gone dormant for a week before today re-lit it — the persistence lives at 20 and 60 days, not in an unbroken daily string.

What a PM should take from the decomposition is where the risk actually sat: Short-Term Momentum alone carried 9.3% of the day's cross-sectional variance, the 97th percentile since 2020, in a session where the market factor carried nothing. Twenty-day realized pairwise correlation is 8.46%, the 4.5th percentile since 2020 but mid-pack against the past three months, and implied one-month single-stock correlation (Cboe COR1M) sits at 9.14 — the options market is paid to expect the index to keep standing still while the names underneath it churn. A book that is flat to the index and long anything with a hot four-week chart has been running one exposure without pricing it. Nvidia's numbers, landing after this mark, reset which names sit at the winner end of tomorrow's sort.
