U.S. equities reversed Wednesday's post-midterm rally on Thursday, November 5, 2026, as chip and AI-linked shares led the tape lower. Yahoo Finance's live market wrap said the Nasdaq Composite (^IXIC) was down about 5% at one point and that the PHLX Semiconductor Index (^SOX) dived about 11%, with Nvidia (NVDA), Micron (MU), and other chip names among the leaders lower. Delayed Yahoo quote data around 8:20 AM PT showed the Nasdaq near 24,653, about 4.2% below Wednesday's 25,736.51 close, the S&P 500 near 7,464, down about 2.9%, the Dow near 52,157, down about 2.3%, and the SOX near 9,357, down about 8.9%.

Protection That Was Cheap Wednesday Turned Expensive Fast

The Cboe Volatility Index, which tracks expected 30-day S&P 500 volatility, closed Wednesday at 16.61 after election hedges were unwound. Delayed Yahoo data had the VIX near 25.63 on Thursday morning, up about 54% from that close, after an intraday high near 28.09 and a low near 16.70. That is the kind of one-session jump that rewrites short-dated SPY, QQQ, and VIX option prices in real time. Live Cboe delayed quotes are the place to check the spot index and the futures curve as the session develops.

Yahoo Finance tied the open selloff to investors still sorting winners and losers after Democrats' midterm sweep, with chip and AI infrastructure names catching the brunt of the move. SPY traded near $744.16 versus Wednesday's $766.81 close, about a 3.0% drop. QQQ traded near $658.87 versus $691.95, about a 4.8% drop. NVDA was near $185.91, down about 7.1% from $200.13.

What a Three-to-Five Percent Index Gap Does to Common Structures

A drop of this size relative to Wednesday's close is large for a single cash session in SPY and larger still in QQQ. Traders who sold short-dated premium into Wednesday's calm VIX often find delta and gamma running against them once the tape gaps and implied volatility lifts together. Covered-call overwriters on Nasdaq names can see calls go from out-of-the-money to deep in-the-money in a morning, while cash-secured put sellers on chip names face assignment risk if strikes that looked remote on Wednesday are now through the stock.

Index and ETF options absorb most of the hedging flow on days like this. Delayed Cboe SPY quotes and Cboe QQQ quotes show where the active strikes and expiries sit; Friday November 6 contracts (the day of the official October jobs report) and the November 20 monthlies are the lines that usually reprice first when VIX jumps more than 50% in a session. Our implied volatility guide covers how index IV tends to rise with realized selling rather than crush the way a single-stock earnings event often does.

Friday's Jobs Report Still Sits on the Calendar

The same Yahoo wrap noted Challenger, Gray & Christmas layoff plans fell in October, setting up Friday's employment report. That means Thursday's vol spike is not only a catch-up to the open selloff; it also rebuilds some of the event premium that had been drained after the midterms. Traders comparing Thursday's realized move with what Friday's SPY and QQQ straddles now charge are separating the chip-led de-risking from the next macro print. The OCC options disclosure document explains the risks of standardized options, including that VIX options settle to VIX futures rather than the spot index.
