Microsoft, Figma among market cap stock movers on Friday

U.S. markets saw broad stock-specific swings on May 15, 2026, with mega-cap Microsoft (MSFT) leading gains after adding former EY chief Di Sibio to its board, sending MSFT higher by roughly 4.4–4.5%. Chip names and other large-cap techs weighed on the market — Arm, Intel and several semiconductor suppliers fell mid-single digits — while renewable and select mid/small-cap names surged (SolarEdge, Enphase, Figma). The moves produced a mixed market tone: strong upside in software and select clean-energy winners contrasted with outsized declines in some miners, chipmakers and SPAC/blank-check names. Overall, the action reflected company-specific news (board additions, corporate financings, director changes and earnings/notes) more than a broad macro-driven sector shift, producing idiosyncratic volatility across market-cap ranges.
