What drove the moves
Several of the largest swings were tied to company-specific news called out during the session.

The breadth of movers spanned semiconductor-related names, software and cloud firms, payments companies, hospitality and travel, biotech and consumer brands.
Market context
Thursday’s tape underscores the degree to which individual-company results and analyst commentary continue to dominate intraday action for many stocks. Winners included companies that posted unexpected strength or raised outlooks, while losers were frequently those citing weaker revenue or profitability commentary or facing downgrades.

Investors saw a mix of outsized winners and losers across market-cap tiers on Thursday, with Arm among the notable gainers and SanDisk among the larger-cap decliners. Mid- and small-cap names produced particularly volatile moves tied to earnings outcomes, guidance changes and rating actions, reinforcing a market environment where company-level developments are producing sharp, rapid repricings.
