Stocks opened defensive and stayed that way, with the S&P 500 closing near session lows as a chip-led selloff and a fresh leg up in crude overshadowed Friday's inflation relief rally.
The tape traded exactly as the macro calendar suggested it should. Brent pushed toward the mid-$100s and WTI back above $100 after a drone strike forced Saudi Arabia to shut a key export pipeline, reviving supply-shock pricing just as the Fed sits down for its two-day meeting. Layered on top, weekend comments from AI lab chiefs floating a slower buildout pace hit the semis complex hard, dragging the SOXX-type names down mid-single digits and pulling the Nasdaq lower even as software and cybersecurity names, along with a handful of mega-cap winners, held up relatively well. Financials lagged behind a trading-revenue warning out of a major bank, and cyclicals like Caterpillar were soft alongside Goldman. The index gave back roughly half a percent, closing below Friday's highs but off the worst intraday levels after a midday bounce faded into the close — a pattern consistent with distribution rather than capitulation.
Into the overnight, the setup is straightforward: FOMC decision and dot plot land Wednesday 2pm with a hike now the base case priced by markets, so positioning risk sits on the outcome and on Chair Warsh's tone versus what's baked in. Vol is waking up off a quiet summer floor, and Friday's triple-witching expiry with roughly two trillion in notional rolling off adds pin risk into the back half of the week.
The risk: oil keeps ripping on Middle East escalation and forces the Fed's hand hawkish even as growth data softens, in which case the semis-led weakness broadens into a real risk-off leg rather than a one-day air pocket.
