Meta, Caterpillar among market cap stock movers on Thursday

Stocks swung sharply on April 30, 2026 as mega-caps and small-caps both posted big moves. Meta (primary instrument) plunged roughly 9-10% after headlines about memory shortages and follow-on guidance/headline-driven selling, while Caterpillar jumped ~8% on a ProPetro unit deal for power generation. Big tech was mixed — Google and Eli Lilly rallied (around +5% and +8%-9% respectively) while Microsoft and Nvidia declined ~4%. Several mid- and small-cap names saw double-digit gains (Qualcomm, Teradyne, Bandwidth, Everspin) or steep drops (Check Point, Acadia, BioScrip). The episode underscores elevated intraday volatility driven by company-specific news, analyst actions and earnings/earnings-related updates, producing a mixed market tone across sectors.
