US Stock Market Summary — May 12, 2026

US equities were broadly rattled in the immediate wake of the April Consumer Price Index (CPI) release. The S&P 500 settled at 7,400.96, slipping 0.16%, while the tech-heavy Nasdaq Composite was hit harder, falling 0.71% to 26,088.20. The Dow edged up 0.11% to 49,760.56 in a narrow gain, supported by defensive healthcare and consumer staples names. April headline CPI came in at +0.6% month-over-month, in line with consensus, but at +3.8% year-over-year (vs. +3.7% expected), it marked the highest annual reading since May 2023. Core CPI rose +0.4% MoM and +2.8% YoY, posting the steepest monthly gain since January. Energy surged +3.8% MoM, accounting for more than 40% of the headline increase, and key categories such as shelter and airfares also moved higher — confirming broad-based price pressures that are difficult to dismiss as pure "Iran-driven energy noise." Markets reacted swiftly: the implied probability of a rate hike by year-end on the CME FedWatch tool climbed to roughly 30%, and a rise in the 10-year Treasury yield triggered a wave of profit-taking in high-multiple tech names.

The session showcased a clear defensive rotation. The healthcare ETF $XLV led the way at +1.96%, followed by consumer staples $XLP at +1.28%, financials $XLF at +0.78%, and energy $XLE at +0.70%. The simultaneous strength in healthcare and staples is a textbook signal of capital rotating into sectors with stronger pricing power, reflecting expectations of resilient margins even in a higher-rate environment. On the other side, tech $XLK fell 1.51%, the weakest of the 11 sectors, with consumer discretionary $XLY down 0.90% and industrials $XLI off 0.39% — a clear pullback in risk appetite. The bond market weakened across the board on inflation concerns, with the long-duration 20+ year ETF $TLT down 0.69% and the 7–10 year $IEF off 0.35% as prices reflected rising yields. Commodities reaffirmed that Iran-linked energy risks remain live, with the crude oil ETF $USO soaring 4.07%, while copper $CPER climbed 2.67% and wheat $WEAT jumped 6.25%, pointing to broad-based price gains.

The biggest shock came from semiconductors. Qualcomm ($QCOM) plunged 11.46% to $210.31, logging its largest single-day decline since 2020, while Intel ($INTC) fell 6.84%, Micron ($MU) dropped 3.61%, Sandisk ($SNDK) slid 6.17%, and Western Digital ($WDC) lost 5.25% as memory and logic chip names were swept up in the selloff. Beyond the rate lift from the hot CPI, reports that South Korea's government is weighing a policy of "citizen dividends funded by an AI windfall tax" added further pressure to memory names with high exposure to Samsung and SK Hynix (Reuters). Corning ($GLW), which surged 10% the previous day, gave back 4.41% as profit-taking hit the name. On the other side, healthcare and networking outperformed. UnitedHealth ($UNH) gained 3.11% and AbbVie ($ABBV) rose 2.51%, drawing defensive flows, while Arista Networks ($ANET) climbed 4.48% and Amphenol ($APH) added 4.41%, buoyed by lingering AI-infrastructure optimism and charting their own course despite the semiconductor rout. Copper strength lifted Southern Copper ($SCCO) +3.52%, and Zebra Technologies ($ZBRA) jumped roughly 13% including extended-hours trading after an earnings beat (CNBC).

> "Inflation is likely to fade into the background over the coming months. Investor attention will pivot to earnings, economic growth, and the AI capex cycle. The Fed has made clear it is willing to look through temporary inflation pulses tied to the Iran conflict."

> — Tim Urbanowitz, Chief Investment Strategist, Goldman Sachs Asset Management

> "The rise in core CPI is a signal that higher energy prices are feeding through more broadly across the economy. It doesn't necessarily mean the Fed will pivot to rate hikes imminently, but it reinforces the reality that new Fed leadership won't deliver an immediate dovish turn."

> — Ellen Zentner, Chief US Economist, Morgan Stanley Wealth Management

> "Both the fact that rising oil costs are being passed through to consumers relatively quickly and the signal that inflationary effects are spreading more broadly are factors that will keep the Fed's inflation concerns alive. The probability of a rate hike this year is still below 50%, but it is clearly trending higher."

The session's data captured short-term overbought conditions in tech (Nasdaq RSI of 77 and $XLK RSI of 78) alongside rising volatility in select financials and consumer names. Whether the memory and semiconductor selloff is a one-off profit-taking episode or the start of a trend reversal will be the key point to watch over the coming days. View the Technical Signals Report
