The Week the AI Trade Came Back

Five days changed the picture. The same 36-name AI infrastructure basket we screened on August 3 — when the median name was up +50.4% year to date and the tape was still shaking from the unwind — closed the week with a median gain of +7.2%. 30 of the 36 names in the basket finished the week higher. The iShares Semiconductor ETF (SOXX) jumped +7.6%, Nvidia closed +11.6% — its best weekly performance in over a year, according to CNBC — and the S&P 500 and Dow both touched record highs, with the Nasdaq up 5.2% on the week.

“Five days changed the picture.”

The catalyst was mostly mechanical. Last week's collapse of Situational Awareness, the leveraged hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, forced a wave of indiscriminate selling across AI infrastructure names — the "clearing event" the market spent July absorbing. With the forced liquidation largely behind it, the trade snapped back, helped by a weaker-than-expected July jobs report (nonfarm payrolls fell by 23,000) that pushed rate-hike odds down and Treasury yields lower. By Friday, traders were pricing a 55% probability the Fed holds rates in September.

A Rebound, Not Just a Recovery

The most interesting thing about the bounce is who led it. This was not a rally in the year's winners — it was a violent snap-back in the year's losers.

Palantir (PLTR) rose +39.8% on the week, CoreWeave (CRWV) +26.3%, Arm (ARM) +17.9%, Marvell (MRVL) +16.6%. Every one of those names was under water or deeply lagging the basket in July. Palantir, the worst performer in our August 3 screener at -29.2% YTD, is now down just -3.2% for the year — one week erased nearly the entire 2026 deficit. Oracle (+13.1% on the week), Intel (+12.7%), Vertiv (+12.7%) and Dell (+11.9%) tell the same story: beaten-down names repriced in a hurry once the forced seller left the market.

The category view makes the rotation explicit. The three strongest groups year to date — Memory & storage (+201% median YTD), Chips (+125.8%), Hardware infra (+68.1%) — were middling-to-negative this week, with memory the only category in the red (median -2.6%). The laggards were the leaders: AI software (one name, Palantir, +39.8%), Neoclouds (+26.3%, CoreWeave), and Chips still managed +12.7%. Money didn't leave the AI trade last week; it rotated inside it.

The Year's Leaders Took a Breather

The one dark spot in an otherwise green week was the memory complex. Western Digital (WDC) fell -20.3% — the worst one-week performance in the entire basket — after Sandisk and Western Digital delivered guidance that failed to excite investors despite solid quarterly results. Sandisk itself was flat (-0.1%) and Seagate (STX) fell -5.1%. CNBC's club commentary read the reaction as company-specific rather than a sign of weakening demand across the AI buildout, and it added Micron to its Bullpen — Micron, at $877.56, remains roughly 28% below its June 25 record close of $1,213.56 even after bouncing sharply off its July 30 lows.

The YTD scoreboard still tells the same 2026 story, just with the edges shaved: Sandisk +411%, Dell +260%, Micron +207%, Seagate +195%, Intel +175% at the top — versus Oracle -24.6%, Constellation Energy -23.6%, Meta -10.3%, Palantir -3.2% at the bottom.

The Rotation, in One Picture

Put the week against the year and the pattern is hard to miss: the points scatter along a downward slope. High YTD, low (or negative) week; low YTD, big week. The only real outlier in the top-right — strong both ways — is Dell (+260% YTD, +11.9% on the week), whose data-center server business keeps printing numbers.

What It Adds Up To

Three takeaways from the week's data:

  • The unwind is priced. The basket's median YTD return improved from +50.4% to +54.5% in five sessions, and the S&P 500's YTD total return moved from +11.4% (Aug 3) to +13.7% (Aug 7). A forced seller is gone, and the reflexivity that dragged good companies below fair value has reversed.
  • The rotation is a feature, not a bug. The 2026 AI trade was never one trade — it's a screener with a 435-point spread between the best and worst YTD performers. What last week showed is that the spread itself is now the tradable signal: when a leveraged seller exits, the names that were pushed down hardest bounce hardest.
  • Guidance is the new battleground. With the liquidation over, earnings and fundamentals are the primary driver again — which is exactly why WDC's -20.3% week happened in a week the S&P hit records. Expect the dispersion we saw in July to re-emerge at the single-stock level every earnings season, even as the basket as a whole grinds higher.

The AI trade didn't just come back last week. It changed which names are leading it. The data says the next leg belongs to whoever can hold the rotation.
