Nvidia's quarter was the catalyst; software was the trade. IGV +7.00% against SMH +2.64%, with the Semiconductors factor itself printing negative — the market bought the layer that does not pay a memory bill. The market factor explained 0.18% of today's cross-sectional variance against a one-year average of 9.3%: index exposure got almost none of this.
Nvidia's fiscal-second-quarter numbers — $96.2 billion of revenue, up 106% year over year, with an October guide of $108 billion Morningstar — drove the whole session, and the stock rose +8.77% in the regular session, adding $421 billion of market value. But the money that followed went into software. Salesforce gained +22.56% on expanded revenue guidance and a deepened Anthropic partnership Bloomberg, CrowdStrike +20.50% and Veeva +15.31% on their own results, Okta +28.26% and Synopsys +13.37% alongside them Bloomberg. Growth printed +0.33% at z=+1.4; Semiconductors printed negative.

Away from the winners the session was a down day. Of the eleven sector SPDRs, only XLK is higher; XLP is the weakest at -1.26% and the median Consumer Staples stock fell -1.43%. Hormel dropped -10.17% in the regular session, its third-quarter sales missing consensus and the full-year revenue outlook trimmed Economic Times. Burlington fell -7.72% on a revenue shortfall that its raised full-year guidance did not offset, and HealthEquity fell -10.32% after a fiscal second quarter that beat on earnings but grew nothing sequentially. Energy is the exception to the exception: XLE is -0.24% while the median energy stock rose +1.37%, Petrobras +2.87% against Exxon -1.11%.

Semiconductor exposure did not pay on Nvidia day, and that is the shape of the print rather than a contradiction of it. Nvidia guided gross margin down from 75% in the July quarter toward 71.5% in January Morningstar; the Korea JoongAng Daily reported Thursday that server prices for the Vera Rubin and Grace Blackwell platforms rise 15% to 17% from early 2027 to cover memory costs, with supplier purchase commitments up 135% sequentially to $279 billion. The same bill is arriving further down the chain: HP's Personal Systems operating margin fell to 4.6% from 5.2% because its price increases did not cover the memory squeeze Morningstar. Buying the software layer is the clean way to own accelerating AI capital spending — $1.3 trillion projected next year across the top five US hyperscalers Morningstar — without owning the bill of materials.
The counterweight is that the chip complex did rise in cap terms: SMH +2.64%, and the memory names themselves are +25.73% over twenty sessions even with DRAM flat today. The factor is measuring something narrower and more useful — once beta and growth are stripped out, the more a name was tilted toward Semiconductors, the less it earned today. And software is not whole: the S&P 500 software and services index remains 12% below its October peak and down more than 3% for the year Economic Times.
Value fell -0.45% at z=-1.9: the cheapest names underperformed the growth-priced end, and the same downward slope from expensive to cheap holds at one day, twenty days and sixty-three. Profitability says it from the other side, -0.34% at z=-1.8, extending a twenty-day run at z=-1.8 — the more profitable names lagged, and the day's biggest gainers sat at the loss-making end of the screen (Rubrik's profitability exposure -2.4σ, Snowflake's -3.5σ). In ETF form: IWF +1.77% against IWD -0.31%, with QUAL managing only +0.34%. This was a repricing of expensive growth, not a bid for quality.

One flow spread ran unusually clean underneath it. Short-Sale Activity printed -0.25% at z=-2.3, in the bottom 2% of its history since 2020: names barely short-sold in Wednesday's Reg SHO flow beat the most heavily short-sold ones by a wide margin the next day, which is the durable direction of the model's most statistically reliable effect. Synopsys, nearly two standard deviations into the barely-short-sold end, is one of the faces of it.
The strongest factor signal of the day had nothing to do with data centers. Bitcoin / Crypto returned +0.74% at z=+2.4, a reading in the 99.8th percentile of the model's history since 2020, and it was driven from the top of the exposure range — MicroStrategy, Circle and SharpLink among the most-exposed names. WGMI gained +4.07% and BITO +2.12%, the latter now +14.38% over five sessions, with bitcoin near $79,313, roughly 41% above its July 1 low and still 37% below the October 2025 high Economic Times. Strive +7.88% and SharpLink +6.61% were almost purely the factor moving them, not company news. The recovery is off a deep hole: the mining complex is still -34.36% over sixty-three sessions.

The market factor explained 0.18% of today's cross-sectional variance against a 9.3% one-year average, with stock-specific moves taking 79.3% versus 66.5% typically. That is the axis a book actually loaded on today: a portfolio holding the index got a +0.57% SPY day out of a session in which single names moved 20 points. Twenty-day realized pairwise correlation sits at 7.90%, the 3.0th percentile since 2020 but the 38th percentile against the past three months — near the lows on the long clock, ordinary against the recent past. Implied one-month single-stock correlation (Cboe COR1M) at 8.77 remains in the lowest ~2% of its twenty-year history, and implied index volatility (Cboe VIX) eased to 14.49 from 15.21.
The quarter's defining pattern also held. Short-Term Momentum is -0.30% today and -8.12% over sixty sessions, meaning last week's leaders have been faded again and again since June. Look at who won today: CrowdStrike and Okta carried Short-Term Momentum exposures of -2.3σ and -1.9σ, fixed before the open from the prior week's returns. The largest single-day gains landed on names the market had just finished discarding.

One more structural signal worth carrying into next week: Morning Activity's twenty-day cumulative return of +1.69% ranks in the 99.4th percentile since 2020 (z=+3.0), and it added +0.19% today at z=+1.6. Names with a habitual early-session trading pattern — an exposure set from trailing behaviour, not from this morning — have been paid for a month straight. After the bell the sequencing turned: Autodesk rose +6.24% in the regular session and gave back -5.38% once it reported, while Marvell fell -1.50% in the session and a further -1.46% after it.
Initial Claims the BLS, released at 8:30 AM ET, showed jobless claims falling to 203,000 for the week ending August 22 against a 208,000 consensus, with continuing claims down to 1.778 million — a labour market that is not shedding workers even as hiring cools. Yields took it as expected: the 10-Year Treasury is at 4.67%, up 0.8 basis points, with the 30-Year at 5.19% CNBC, and the Treasury (Duration) factor at -0.45%, z=-1.4, marked long-duration equities down alongside it.

5/20/60d windows include today's session; 1d is the previous session.
Pairwise realized correlation. Index variance net of the weighted idiosyncratic diagonal, over the cross terms — the estimator used for implied-correlation indices. 20-day window unless noted; history since 2020.
Market variance share. The fraction of cross-sectional variance explained by the market factor — the attribution companion to pairwise correlation, not a substitute for it.
Factor z-score. Today's factor return divided by its daily-return standard deviation over ~1,600 trading days.
Conditional importance. A factor's relative share of what a tree-based fit of today's stock returns explains; sums to 100% across factors.
High-beta momentum cohort. US names above $2B market cap in the top quintile of both raw beta and 12-month momentum; membership frozen at each month's first business day. “Top 50” = the 50 strongest by combined rank.
Dispersion (realized). Total cross-sectional volatility net of the market component; high dispersion is the flip side of low correlation.
Stock-specific (idiosyncratic) return. The part of a stock's move not explained by market, style, or thematic factors in our decomposition.
