TECHThe NASDAQ fell 2.60% to 26,008.86 — its worst session since June — led by semiconductor and optical networking stocks; Lam Research (LRCX) -11.76%, Coherent Corp (COHR) -12.51%, Lumentum (LITE) -11.54%, and Ciena (CIEN) -10.71% were the four worst S&P 500 performers in the technology space, all closing sharply lower on the session with risk of continued pressure Friday given Asia's overnight weakness.
TECHModerna (MRNA) was the S&P 500's single worst performer, falling 17.57%, in a move that crossed sector lines — the healthcare-adjacent biotech dragged on both the NASDAQ and the broader health care sector despite XLV finishing up 1.32%, suggesting the selloff was stock-specific rather than sector-wide.
CONSUMERConsumer staples (XLP +3.31%) was the day's top-performing sector as investors rotated into defensives; Procter & Gamble (PG) showed earnings strength, and Campbell's (CPB) was the S&P 500's fourth-largest gainer at +8.69%, reflecting a clear flight to predictable cash-flow names amid tech and geopolitical uncertainty.
INDUSTRIALSPool Corporation (POOL) surged 14.36% and Allegion (ALLE) gained 11.02% — the day's top two S&P 500 performers — while Roper Technologies (ROP) added 9.73%, all classified as Industrials; this outperformance, alongside Lennar (LEN) +8.69% in consumer cyclicals, points to earnings-driven individual stock strength that bucked the macro risk-off tide.
ENERGYDespite energy being a laggard sector on Thursday (XLE -0.87%), crude oil's sharp rally — WTI +2.39% to $99.47/bbl, Brent +4.00% to $113.17/bbl — driven by Middle East infrastructure attacks and Persian Gulf shipping disruptions, sets up a more constructive Friday tone for US-listed integrated energy and upstream names as the geopolitical risk premium persists.
MACROUS flash manufacturing PMI (forecast 55.4, prior 57.0) and services PMI (forecast 57.9, prior 58.7) at 09:45 ET, followed by revised UoM Consumer Sentiment (forecast 46.3, prior 46.3) and UoM Inflation Expectations at 10:00 ET, are the key data releases for Friday's session; with the Fed meeting October 28 and 10-year yields at 5.13%, any downside PMI miss could reignite rate-cut speculation, while a beat alongside elevated oil prices could reinforce the hold narrative.
