NextFin News - U.S. stocks closed modestly higher Thursday on the first trading day of October, recovering from a choppy session as Treasury yields retreated from their recent multiyear highs and semiconductor stocks led a tech-driven rebound. The session's central tension eased somewhat from the prior day: a fresh round of commentary characterized Wednesday's PCE inflation data as more technical noise than a genuine policy signal, and with that uncertainty settling, investors turned their attention back to a memory-chip sector that finally delivered the stock reaction many had expected from Micron Technology's blowout earnings report one session earlier.

The Nasdaq Composite advanced 0.04%
Stock & Sector Performance
Semiconductors were the standout sector of the session, led decisively by Micron Technology, which rose 3.03% as investors more fully digested the company's fiscal fourth-quarter beat and raised first-quarter outlook reported after Tuesday's close. The move marked a notable shift from Wednesday's muted reaction, when shares had traded only modestly higher despite revenue, earnings, and margins all clearing Wall Street's official estimates. Small-cap stocks remained the market's clear laggard heading into the new quarter: the Russell 2000 had fallen more than 5% in September, pushing its third-quarter decline to roughly 7.5%, a sharp underperformance relative to the broader large-cap recovery.
Magnificent Seven trading was not the session's dominant story, though the semiconductor sector's strength - anchored by Micron - suggests continued participation from AI-linked mega-cap names in the broader tech rebound.
Hot Sectors to Watch
Memory semiconductors delivered the clearest confirmed trend of the session, and the one-day lag between Micron's earnings release and its actual stock reaction is itself a useful signal about how the market is currently processing AI-infrastructure results. Rather than reflecting disappointment, Thursday's 3.03% gain suggests investors needed a full trading session to work through the nuances of Tuesday night's print — distinguishing between the company's clean beat on official Wall Street estimates and the more elevated "buyside" expectations that had initially tempered Wednesday's reaction — before ultimately rewarding the quarter's underlying strength, including revenue up 379% year-over-year and a first-quarter revenue guide roughly $4.5 billion above consensus. This pattern, a beat-and-raise quarter that takes a session or more to be fully priced in rather than triggering an immediate pop, is worth watching for whether it recurs across the rest of the memory and AI-infrastructure earnings cycle this quarter.
Major Story of the Day
The delayed market reaction to Micron's earnings was the dominant story shaping Thursday's session. After trading only marginally higher Wednesday despite results that beat Wall Street on revenue, adjusted EPS, and gross margin — plus a first-quarter fiscal 2027 guide of $61.5 billion in revenue, well above the roughly $57 billion consensus — Micron shares advanced 3.03% Thursday as the broader semiconductor complex rallied alongside it. The move helped power the Nasdaq's recovery from an earlier choppy stretch in the session and underscored memory chips' continued role as a bellwether for the broader AI-infrastructure trade heading into the fourth quarter. Separately, Kyle Rodda, senior financial market analyst at Capital.com, offered a retrospective read on Wednesday's inflation data that helped frame Thursday's calmer tone, saying the PCE report "proved to be all technical in nature, arguably leaving the markets in a greater state of uncertainty than before the release," after methodological changes had pulled the annual core PCE reading down to 3% against a 3.3% forecast.
