Market Overview
This was a sharp reversal week in the S&P 500. The index opened near 7650 and was grinding sideways-to-higher through Wednesday, then got hit with a single-day wipeout on Thursday that reset the whole tape. The shape of the week is a classic "trap and drop": buyers pushed to a high of 7746.5 mid-week, then price collapsed to a low of 7381.0 by Thursday, leaving a 365.5-point range that tells you everything about the volatility environment. VIX opened the week at 19.05 and closed at 25.64, a move that reflects real institutional fear, not just noise.
Monday started the week with a pullback, with tech and AI-linked names already under pressure ahead of the midterm results. Wednesday's pop was a post-election relief rally, the best day in roughly three months, as markets initially processed the midterm outcome.
Then Thursday happened. A brutal sell-off swept through Wall Street, led by stocks tied to the buildout of AI data centers, and the wipeout more than erased the prior day's gain. Democrats swept the U.S. midterm elections, sparking a sell-off in AI and data center stocks. Democratic winners and progressive lawmakers called for tougher limits on AI and data centers after the 2026 midterm results, with some calling for a national data center moratorium. The concentrated positioning in mega-cap tech turned a policy-driven narrative shift into a waterfall move: the S&P 500 posted its worst day since the April 2025 tariff shock.
On Friday, jobs data came in hot, with nonfarm payrolls well above consensus and unemployment falling to 4.1%, which raised market odds of a December Fed hike. The market barely moved, closing essentially flat on the day, suggesting buyers weren't ready to step in front of the macro uncertainty.
