Wall Street closed sharply lower on Tuesday as a global technology selloff accelerated, sending the Nasdaq and S&P 500 to their steepest single-day drops in weeks. The catalyst was a combination of an unexpected note from Bank of America economists forecasting three Federal Reserve rate hikes before year-end and a steep overnight slide in Asian semiconductor stocks — factors that rattled investor confidence in the AI-driven rally that has defined much of 2026.
What Moved Markets
The Nasdaq Composite bore the brunt of the selling, dropping 2.21% to close at 25,587.04, a loss of roughly 578 points. The S&P 500 fell 1.44% to 7,365.46, giving back a meaningful chunk of recent gains. The Dow Jones Industrial Average held up relatively better, slipping just 45.87 points — or 0.09% — to finish at 51,666.84, cushioned by strength in healthcare and consumer staples names that investors rotated into as a defensive play.
The Bank of America note was the early morning shock. BofA economists revised their 2026 rate outlook, now penciling in quarter-point hikes in September, October, and December — a sharp reversal from their prior expectation of steady or declining rates. That shift reignited concerns that the Federal Reserve, already signaling hawkish intentions at last week’s meeting, may need to fight a prolonged battle against inflation fueled by rising oil prices linked to the ongoing conflict in the Middle East. Higher rates are particularly painful for high-multiple growth and technology stocks, which tend to see their valuations compress when borrowing costs rise.
Adding fuel to the fire, South Korean markets had already sold off hard overnight, with the Kospi index sliding 4.07% as semiconductor heavyweights SK Hynix and Samsung Electronics each fell more than 4%. That weakness crossed the Pacific and hit U.S. chip stocks at the open.
Notable Movers
Nvidia (NVDA) was among the most-watched decliners, falling 3.2% to close near $202. The stock has been the poster child for the AI investment boom, but Tuesday’s action showed just how quickly sentiment can shift when the rate backdrop turns less friendly. Micron Technology (MU) had an even rougher session, shedding roughly 11.4% and closing near $1,075. Investors are positioning defensively ahead of Micron’s fiscal Q3 2026 earnings report due Wednesday, with analysts expecting strong results but the risk-reward on a day of broad sector weakness skewed sharply to the downside. Taiwan Semiconductor Manufacturing (TSM) also fell around 5.2%.
The VanEck Semiconductor ETF (SMH) lost approximately 6.5%, giving retail investors a clear window into just how widespread the damage was across the chip sector.
On the winning side, IBM (IBM) bucked the trend in a meaningful way, surging roughly 5.3% after JPMorgan upgraded the stock from Neutral to Overweight and set a price target implying substantial upside. The bank cited IBM’s software-heavy business mix — software accounts for about 45% of revenues but roughly two-thirds of profits — as a reason the stock deserves a higher multiple, particularly as Red Hat and OpenShift adoption accelerates. IBM’s relatively low AI-capex exposure made it a natural safe harbor on a day when investors were fleeing high-spend tech names.
Defensive stalwarts including Walmart (WMT), Procter & Gamble (PG), and Johnson & Johnson (JNJ) all posted modest gains as investors sought shelter from the tech storm.
Looking Ahead
Micron’s earnings after Wednesday’s close will be the next major test for the semiconductor sector. Analysts are watching for commentary on HBM4 memory demand tied to Nvidia’s Vera Rubin platform, as well as any updates to fiscal 2027 guidance. Beyond that, the week’s big macro event arrives Thursday with the release of May PCE and core PCE data — the Federal Reserve’s preferred inflation gauge. A hotter-than-expected reading would likely validate the Bank of America rate hike thesis and could extend the selling pressure on growth stocks. Investors should also keep an eye on any further developments out of Asia, where chipmaker volatility has shown it can move U.S. markets well before the opening bell.
