Today's biggest movers. Our screens cover mega-cap down to micro-cap and surface the catalyst behind the move.
SK hynix Inc. (SKHY) drops sharply after its Nasdaq listing lockup expires, creating a near-term supply overhang. The move comes despite strong AI-memory fundamentals, a recent EPS beat, and supportive sector demand signals from Samsung.
Arm Holdings plc American Depositary Shares (NASDAQ: ARM) drops after the Qualcomm royalty trial begins, pressuring the stock alongside a weaker semiconductor tape. The move reflects legal risk to a key revenue stream, even as Arm’s long-term AI and licensing story remains intact.
Marathon Petroleum Corporation (MPC) rises after Mizuho Securities sharply lifted its price target, adding to momentum from strong refining margins and solid recent earnings. The stock’s move comes despite below-average volume and a price that now sits above the revised target, keeping the setup mixed for new buyers.
Chipotle Mexican Grill, Inc. (CMG) rises after Reuters reported Starbucks has explored a takeover, sparking control-premium speculation. The move came on heavy volume and reflects headline-driven buying rather than a fresh earnings update. Investors are weighing takeover optionality against Chipotle’s standalone fundamentals.
argenx SE (ARGX) falls sharply after the company stopped its Phase 3 UNITY trial in Sjögren's disease for futility. The selloff outweighs positive FB102 celiac data, as investors reassess pipeline expansion prospects and the stock's valuation after a major late-stage setback.
Corning Inc (GLW) rises after UBS lifted its price target and investors continued to focus on the company’s major AT&T and Verizon fiber agreements tied to AI infrastructure. The rally reflects growing confidence in Corning’s long-term networking growth, though the stock’s rich valuation still calls for discipline.
Marvell Technology, Inc. (MRVL) rises after its Investor Day spotlighted a long-term AI infrastructure strategy in New York. The stock jumped on heavier trading as investors reacted to management’s roadmap for custom AI accelerators, optical interconnect, and networking silicon. Valuation remains rich, so execution will matter.
Constellation Energy Corporation (CEG) climbs after Google announced a $4.3 billion, 20-year nuclear power agreement tied to 890 MW of new capacity. The deal highlights Constellation’s role in powering AI data centers and hyperscalers, sending shares sharply higher on heavy trading volume.
Western Digital Corporation (WDC) drops after a report that Toshiba is expanding hard-drive production, reviving supply concerns in the AI-storage trade. The move looks more like a positioning reset than an earnings-driven breakdown, as recent results still showed strong revenue growth, margin expansion, and EPS beats.
Seagate Technology Holdings plc (STX) drops after Toshiba’s reported plan to double HDD capacity for AI data centers raised fresh concerns about pricing power and supply discipline. The selloff comes despite strong financial results, highlighting how quickly valuation can reset when the market questions future margins.
Palo Alto Networks, Inc. (PANW) rises into fresh breakout territory after topping its 52-week high. The move is driven by cybersecurity sector strength, AI-security demand, and supportive analyst and earnings updates, though the stock’s premium valuation and light relative volume call for discipline.
GE Vernova Inc. (GEV) rises sharply as investors stay focused on AI power infrastructure, grid upgrades, and electrification demand. The move comes despite light trading volume, with the company’s raised revenue outlook and large backlog keeping the long-term story intact.
