Stocks ticked lower Friday as the market absorbed President Donald Trump's latest comments on geopolitical tensions and the Federal Reserve.

These stocks made moves:

Micron Technology jumped 7.8%. Board member Mark Liu snapped up $7.8 million worth of shares, according to a securities filing. Purchases by corporate insiders tend to signal conviction in a company's growth story -- and that's particularly notable given how well Micron has performed lately. The stock has risen 237% in 12 months, thanks to stellar earnings that reflected sky-high demand for flash memory chips.

Memory-chip maker Sandisk traded rose 1.1%. Shares closed up 5.5% on Thursday after two analysts hiked their price targets.

Hard-drive maker Western Digital, which spun off Sandisk in February 2025, fell 0.3%, while peer Seagate Technology added 1.9%.

GE Vernova advanced 6.1%. The Trump administration is pushing PJM, the nation's largest electricity grid operator, to hold a special auction to supply data centers. Trump on Friday signed an agreement with several governors from states in the mid-Atlantic region to encourage the construction of power plants.

Shares in Constellation Energy and Vistra, the owners of existing plants, sank 9.8% and 7,5%, respectively.

AST SpaceMobile soared 14%, extending gains from the previous session when it advanced 6.3%. The satellite-communications company was selected as one of the eligible vendors to the U.S. Missile Defence Agency, in the latest tranche of awards for its SHIELD program.

Mosaic tumbled 4.5%. In an earnings pre-announcement, the chemical company said fourth-quarter fertilizer demand had fallen well beyond normal seasonal softness. Mosaic expects phosphate sales volumes of 1.3 million tons and potash sales volumes of 2.2 million tons.

U.S.-listed shares of Novo Nordisk climbed 9.1%. The drugmaker secured approval for a higher dose of its blockbuster weight-loss treatment in the U.K. The Medicines and Healthcare Products Regulatory Agency approved a maximum dose of up to 7.2 milligrams per week of Wegovy, a step up from the previous 2.4 mg limit.

ImmunityBio surged 40% after spiking 31% in Thursday's session. The biotech company expects full-year revenue from its bladder cancer drug Anktiva to surge 700% year over year to $113 million. Earlier this week, Immunitybio said the Saudi Food and Drug Authority had approved Anktiva for the treatment of patients with non-small cell lung cancer.

State Street declined 6.1%. The bank posted lower revenue in the fourth quarter, despite achieving "record revenue" of nearly $3.7 billion. Net income fell to $747 million from $783 million last year. Earnings came in at $2.42 a share, below the $2.79 analysts had expected.

Regions Financial slid 2.6%. The parent company of Regions Bank parent reported net income of $534 million for the fourth quarter, flat over the prior year. Adjusted earnings of 57 cents a share missed the 61 cents Wall Street had forecast.

PNC Financial Services gained 3.8% after fourth-quarter earnings topped analysts' estimates, with the company citing loan growth and higher demand for its financial services.

J.B. Hunt Transport Services fell 1%. Fourth-quarter sales declined 2% as prices and volumes fell across different parts of the business. Shares may have gotten ahead of themselves -- a 50% rally over the past three months has left the stock trading at about 29 times expected earnings, up from about 20 times earnings before the run started.
