Stock futures inched higher early Wednesday, recovering from a slight pullback in the prior session. Investor sentiment remains cautious, however, after Federal Reserve Chair Jerome Powell warned about the difficult balance the Fed faces in controlling persistent inflation while avoiding further labor market weakness.

Here are some of Wednesday's biggest stock movers:

BIGGEST STOCK GAINERS

* LITHIUM AMERICAS (NYSE:LAC [https://seekingalpha.com/symbol/LAC]) +78 - Shares surged after reports surfaced that the Trump administration is seeking up to a 10% equity stake in the company while renegotiating terms of its $2.3B Department of Energy loan for the $3B Thacker Pass lithium project. The project, approved by Trump in his first term, closed its DoE loan under the Biden administration, but officials are now pushing for revised terms amid weak lithium prices and repayment concerns.
* MICRON TECHNOLOGY (NASDAQ:MU [https://seekingalpha.com/symbol/MU]) +2% - Shares gained after the company posted strong FQ4 results and guidance. For FQ1, EPS is projected at $3.60–$3.90, much above the consensus of $3.10, with revenue seen at $12.2B–$12.8B, surpassing the consensus of $11.91B. CEO Sanjay Mehrotra highlighted record FY25 data center performance and said Micron enters FY26 with its “most competitive portfolio to date,” well-positioned to capture AI-driven demand.

BIGGEST STOCK LOSERS

*
COHU (NASDAQ:COHU [https://seekingalpha.com/symbol/COHU]) -9% - Shares sank after the company announced a $200M private offering of convertible senior notes due 2031, with an option for purchasers to buy an additional $30M. Proceeds will be used to fund capped call transactions and for general corporate purposes.
