Alphabet shares slid after key researchers exited for competitors, while AeroVironment and CoreWeave dropped on earnings-related and disclosure concerns.

What drove the move
Several of the biggest movers were reacting to personnel shifts, corporate actions, or changes to financial reporting.
Alphabet slid nearly 6% as reports indicated that two high-profile researchers left the company to join competitors in recent days. The departures came shortly after Google engineering vice president Noam Shazeer said he was joining OpenAI, while John Jumper’s decision to leave Google DeepMind followed days later. The stock decline reflected investor focus on talent flows in AI and perceived implications for research execution.
AeroVironment fell about 11% after the drone manufacturer said it would restate earnings for the three- and nine-month periods ending Jan. 31. The company attributed the restatement to an error in how the carrying value used in a goodwill impairment analysis of its Space reporting unit was calculated. Such corrections often raise questions about internal controls and the accuracy of impairment assumptions, pressuring shares.
CoreWeave lost nearly 9% after late last week’s disclosure of insider sales by several senior executives. According to an SEC filing, CEO Michael Intrator sold holdings worth more than $35 million under a 10b5-1 trading plan. Markets frequently interpret insider selling as a signal of caution, even when it follows pre-set schedules.
Super Micro Computer rose almost 14% after announcing delivery of a Data Center Building Block Solutions Blueprint based on Nvidia’s Vera Rubin NVL4 platform. The company said the new product is intended to accelerate AI buildouts for scientific research. The move suggested investors viewed the blueprint as reinforcing demand prospects for AI infrastructure, especially as buyers pursue faster deployment of data center capacity.
M&A and deal headlines reshaped sentiment
Healthcare and construction-related stocks gained sharply following acquisition announcements.
Apogee Therapeutics surged nearly 47% after AbbVie said it will buy the biotech company. AbbVie will acquire Apogee for $135.11 per share in cash, valuing the deal at $10.9 billion, representing a 49% premium versus Thursday’s close. AbbVie said the transaction will accelerate Apogee’s presence in the respiratory space, while Apogee shares were up about 7% following the announcement. For investors, the premium and strategic rationale supported the stock’s rapid repricing.
Arcosa climbed about 7% after rival building materials maker CRH agreed to purchase Arcosa for $150 per share in cash, or $8.5 billion. The offer represented a 10% premium from Thursday’s close. CRH said Arcosa’s construction products business would complement its existing portfolio, a framing that appeared to resonate with investors seeking scaling opportunities in construction supply chains.
Broader stock performance: software, rockets and memory
Beyond deal-related gains and earnings-related drops, several other technology and industrial names moved on guidance, coverage changes, or trading patterns.
Salesforce shares were down more than 2% and were on track for a 14th straight losing session. The company’s stock has declined nearly 30% over those 14 trading days and is off nearly 44% in 2026. The weakness was tied to fears that artificial intelligence could disrupt software company business models, a concern that has pressured the group during periods when investors reassess long-term revenue durability.
SpaceX shares dropped for a sixth straight session on the Nasdaq, falling more than 10% in the latest move. The stock is down roughly 18% from its closing high last Tuesday but remains up more than 20% versus its $135 IPO price. The pattern suggested profit-taking and volatility rather than a fundamental reset, although the repeated declines kept investor attention on near-term trading momentum.
Getty Images surged 115% after announcing an agreement with OpenAI. The company said its content will appear on OpenAI search and ChatGPT. The scale of the move implied investors saw new monetization or distribution leverage from generative AI partnerships, even as the long-term economics were not detailed in the trading update.
Credo Technology gained more than 8% after Evercore ISI initiated coverage with an outperform rating. Analysts said the market currently views the company as a copper-related AI connectivity play, but it could increasingly be seen as an optical one as it executes its product roadmap. That dual framing supported expectations for potential category expansion.
Micron Technology rose nearly 6% following two brokerage price target increases. Bernstein raised its forecast to $1,300, while Needham hiked its outlook to $1,550. Memory peers moved in sympathy, with Seagate Technology up about 1% and Sandisk advancing nearly 6%, indicating the strength was not isolated to one stock.
Other notable movers
Visteon Corp added about 7% after upgrades to overweight from Barclays and JPMorgan. JPMorgan upgraded Visteon to overweight from neutral, saying the company is positioned to drive significant outgrowth through automotive and related verticals. Barclays said Visteon’s growth story is re-emerging, helping reinforce a more constructive view of demand and earnings trajectory.
Cargo and energy-linked news also supported pockets of the market: Chevron rose about 1% after announcing it will fuel a Microsoft data center in West Texas with natural gas. The 20-year agreement will support a data center labeled “Project Kirby,” estimated to consume 2.7 gigawatts of electricity, with power scheduled to begin in 2028.
Investors will likely keep watching near-term catalysts across the market, including follow-through on AI-related infrastructure and partnerships, the risk of further corporate updates tied to restatements and disclosures, and additional deal developments in healthcare. In the broader macro calendar, upcoming corporate earnings and rate-related signals from central banks and economic data releases remain key for determining whether today’s stock moves extend beyond company headlines.
