Stock Market Update Monday May 18, 2026 President Trump’s midafternoon remarks that “serious negotiations are now taking place” helped stabilize investor sentiment and prevent a second consecutive equity selloff, with a late-session rally lifting the S&P 500 back to flat on the day. Trading today saw tech sector weakness and a pause in the AI stock surge as investors await NVIDIA's earnings. Profit-taking was expected after strong semiconductor and AI gains. Semiconductor declines hit riskier memory and AI infrastructure stocks harder; SanDisk and Micron fell ~6%, NVIDIA ~1.3%. Software stocks showed strength (IGV up ~1.2%), indicating a shift to more stable tech areas. Energy stocks rose with crude oil and geopolitical risks. Financials recovered, with selective investment in cyclical, value sectors.
Away From Stocks: Treasury curve steepened modestly as front-end yields eased, with the two-year Treasury yield declining two basis points to 4.07%, while the 30-year Treasury yield edged higher to 5.14% from Friday’s 5.12% close. The move reflected a combination of moderating near-term rate expectations alongside lingering long-duration inflation and fiscal concerns. Commodity markets remained firmly bid, with WTI crude oil holding above $101 per barrel amid persistent geopolitical risk premiums. Safe-haven demand also resurfaced across precious metals, driving gold higher to $4,565 per ounce. In digital assets, bitcoin traded modestly lower, slipping below the $77,000 threshold, while equity volatility expectations eased, with the VIX declining below 18, signaling a partial retracement in near-term market stress.
