Market overview

U.S. Market Overview — October 23, 2026

Risk tone: Markets were in a mild risk-off mode to close the week. The VIX closed at 19.45 after ending at 19.03 on October 22 and 16.68 on October 21, confirming the modest pickup in hedging demand implied by the elevated ATRs in the measured data. The major averages fell on Friday as higher oil prices weighed on sentiment ahead of next week's Fed policy meeting.

Main driver — AI capex anxiety: The proximate catalyst was a shift in the AI narrative following Thursday's (Oct 22) "Magnificent Seven" earnings. "Tech stocks got slammed amid fresh concerns about the outlook for artificial intelligence," said Kyle Rodda, senior financial market analyst with Capital.com, adding that "the flavor of this sell-off was starkly different... the concern pertains to capital expenditure... rather than the risk that AI hyperscalers are spending too much, the proverbial script has flipped." Specifically, the volatility was stoked by the first batch of Magnificent Seven results, as Meta Platforms left unchanged its CAPEX guidance and provided little color about future plans, while Tesla reduced its full-year CAPEX guidance by 20%. This fits the equal-weight breadth and tech-lag pattern in the measured data (QQQ underperforming SPY by ~4% over 1m), since the de-rating was concentrated in AI/hyperscaler names rather than the broad market.

Rates and the Fed: Treasury markets whipsawed during the week. The tech sell-off on Thursday sent investors rushing into bonds, pushing the 10-year Treasury yield to its biggest one-day drop in more than two years and back below 5%, before yields crept back up by Friday — with the 2-year Treasury yield rising 2 basis points to 4.6625% as markets looked ahead to the Fed's meeting the following week. Investors had been bracing for a rate hike to combat fears of oil-driven inflation, but those bets faded quickly, with Fed funds futures putting the odds of an October hike at about 5%, down from 15%.

Sector/standout moves: Energy and oil-sensitive sectors outperformed as crude prices continued to hover around recent highs amid several untenable conflicts in the Middle East that risk global energy supply, consistent with energy leading the tape on the day. Semiconductors bore the brunt of the AI-capex repricing — chip stocks tumbled with the Philadelphia semiconductor index down roughly 6.7% on Thursday's session — though some chipmakers staged a partial bounce Friday as Microsoft ticked higher while Micron Technology and Advanced Micro Devices posted gains of nearly 3% and almost 2% respectively.

Bottom line: The measured levels — SPY down modestly (-0.52% session), QQQ roughly flat on the day but down nearly 5% over the month, DIA down more on the session but up over the month, and RSP/breadth outperforming SPY — are consistent with this week's news flow: a tech/AI-capex-driven de-rating concentrated in mega-cap growth names, a modest but real rise in volatility (VIX ~19.5), partial rotation into cyclicals/value (Dow, equal-weight) and energy on oil strength, and continued reduction of speculative risk appetite (XBI underperformance) as investors de-risk ahead of the Fed's upcoming policy meeting.
