S&P 500 rotation trade faces 3-way test on Big Wednesday

The S&P 500 added 0.2% to 7,428.78 Tuesday, but the modest gain masked a deepening rotation out of technology stocks ahead of a pivotal Wednesday.

"The market is pricing in two competing narratives — that AI spending will keep growing and that it won't deliver returns fast enough to justify current valuations," said Michael Wilson, chief equity strategist at Morgan Stanley.

The Dow Jones Industrial Average jumped 537 points, or 1%, to 52,747.32, while the Nasdaq composite fell 0.2% to 24,876.91, briefly touching 9.3% below its record. Micron Technology dropped 8.9%, Advanced Micro Devices fell 8.1%, and Applied Materials lost 7.8%, making semiconductors the worst-performing sector. Coca-Cola climbed 5%, Sherwin-Williams rallied 8.3%, and Illinois Tool Works rose 3.6% after each beat earnings estimates.

The two-day stretch will determine whether the rotation into value and cyclical stocks has staying power or whether tech reasserts its dominance. Meta Platforms and Microsoft report Wednesday, followed by Amazon on Thursday, with combined market capitalizations exceeding $8 trillion.

The selloff in chip stocks extended globally. South Korea's Kospi index plunged 10.8%, driven by sharp drops in SK Hynix and Samsung Electronics, as traders worried that progress in China's chipmaking equipment capabilities could threaten the competitive position of global leaders. Morningstar equity analyst Jing Jie Yu called the selloff "largely a knee-jerk reaction and overdone."

Despite the Nasdaq's decline, advancing stocks outnumbered decliners on the New York Stock Exchange by a roughly 2-to-1 ratio, and the Russell 2000 index of small-cap stocks rose 0.25% to 2,954, extending its year-to-date leadership. The divergence shows a market broadening beyond the handful of mega-cap tech names that drove the first half of 2026. The Cboe Volatility Index held near 18, below its one-year average, suggesting the tech selloff has not triggered broad market stress.

Falling oil prices provided a tailwind for the broader market. Brent crude settled at $82.08 a barrel, down 4.4%, while West Texas Intermediate fell 4.15% to $79.18, both at two-week lows as hopes for a resolution to the Iran conflict weighed on prices. The drop in energy costs helped push the 10-year Treasury yield down to 4.60% from 4.65%, and traders trimmed bets on a Federal Reserve rate hike to a 31.5% probability, down from 36% a day earlier.

The Fed concludes its two-day meeting Wednesday, with Chair Kevin Warsh widely expected to hold rates steady. But the bigger event may be earnings from Meta and Microsoft after the close. Both companies are among the largest spenders on AI infrastructure, and any signal of reduced capital expenditure plans could accelerate the tech selloff. Amazon reports Thursday.
