U.S. equities saw heightened intraday activity with mega-cap tech and high-volatility small caps dominating today’s most-traded list. Nvidia, Tesla, Opendoor, SoFi, and Pfizer were among the top names drawing significant investor attention, as volumes surged well above typical levels across tech, EV, and AI-linked stocks.
Nvidia (NVDA) topped the volume leaderboard, trading 169.9M shares, but slipped 1.88% to $186.60, extending pressure on semiconductor counters despite sustained long-term momentum.
Ondas Holdings (ONDS) logged 152.7M shares—over double its 3-month average—falling 12.88%, marking one of the steepest declines among high-volume U.S. stocks.
Opendoor Technologies (OPEN) also saw elevated action with 152.4M shares traded, dipping 3.45% as housing- and interest-rate–sensitive stocks remained under pressure.
In mega-cap moves, Tesla (TSLA) climbed 1.13% to $408.91 on strong 96.8M share turnover, outperforming broader tech and helping stabilize sentiment across large-cap growth stocks.
AI and fintech names were mixed.
• BigBear.ai (BBAI) slid 8.09%, continuing volatility in small-cap AI plays.
• SoFi (SOFI) dropped 2.80%, despite volume remaining near its long-term average.
Plug Power (PLUG) fell 7.13%, while Quantum Computing Inc. (QUBT) jumped 8.49%, making it the day’s standout gainer among the most actively traded U.S. stocks.
Defensive interest lifted Pfizer (PFE) marginally higher by 0.08%, holding steady on 72.7M shares traded.
Ford (F) closed lower by 2.35%, with 66.1M shares changing hands as cyclical auto stocks tracked broader market softness.
With several high-volume names trading at or near the lower end of their 52-week ranges, analysts noted strong short-term positioning and momentum-driven flows across the session.
