Today's biggest movers. Our screens cover mega-cap down to micro-cap and surface the catalyst behind the move.
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.
Dell Technologies Inc. (DELL) rises after Mizuho raised its price target, adding fuel to an already strong AI infrastructure rally. The stock is near its 52-week high as investors weigh robust earnings, record AI server orders, and a stretched valuation.
United Microelectronics Corporation (UMC) drops sharply after investors react to a planned $1.8 billion overseas convertible bond offering. The move comes despite solid quarterly results, highlighting dilution concerns and a higher bar for per-share returns as UMC funds new capacity and expansion projects.
C.H. Robinson Worldwide, Inc. (CHRW) falls after announcing a $5.8 billion stock-and-cash acquisition of RXO. Investors are weighing dilution, financing needs, and integration risk, even as the logistics company’s recent earnings and operating performance remained solid.
Space Exploration Technologies Corp. (SPCX) rises as traders react to a busy launch calendar, positive sentiment, and heavy options flow. The stock is also getting support from a recent earnings beat, but the move appears driven mainly by operational milestones and positioning rather than a new fundamental reset.
Seagate Technology Holdings plc (STX) rises after a sharp selloff, as traders buy the dip following Toshiba’s HDD capacity plans and Goldman Sachs naming the stock a tactical idea. Strong fiscal 2026 results and AI storage demand support the rebound, but valuation and supply risk remain key concerns.
