US stock futures were rising modestly Tuesday following a deep selloff in technology stocks after Chinese company DeepSeek rattled markets with a cheaper artificial-intelligence model. Limiting gains, however, were comments from President Donald Trump that he wanted higher across-the-board tariffs than those proposed by new Treasury Secretary Scott Bessent.

These stocks were poised to make moves Tuesday:

Nvidia rose 4.7% in premarket trading after shares of the leading maker of artificial-intelligence chips sank 17% on Monday on the DeepSeek news. Nvidia shed $592.7 billion in market capitalization on Monday, the largest-one day market cap decline for any public company on record. The drop in its value pushed down Nvidia’s ranking of the largest U.S. companies by market cap to third from first, behind Apple and Microsoft.

Concerns over DeepSeek sent a broad swath of AI-related stocks lower. Broadcom, the semiconductor and software company, sank 17% on Monday, the stock’s largest percentage daily drop since March 16, 2020, when it fell nearly 20%. Marvell Technology, meanwhile, tumbled 19%. Broadcom was up 4% in premarket trading, while Marvell gained 3.3%.

AI energy and infrastructure stocks also tanked Monday following the DeepSeek developments. Utility company Vistra Energy Corp., the second-largest owner of independent nuclear plants, fell the most, dropping 28% and ending the session as the worst stock in the S&P 500. DeepSeek said it can operate with much less computing power than the giant data centers that big American tech companies have been building. Vistra rose 4.9% in premarket trading.

Nucor rose 0.4% after the steelmaker reportedfourth-quarter earningsthat fell from a year earlier on lower steel prices. Nucor had warned in mid-December that profits would fall because of lower volumes and average selling prices. The company posted earnings of $1.22 a share, down from $3.16 a share a year earlier, but higher than management expectations of 55 cents to 65 cents.

Earnings reports are expected Tuesday from Boeing, General Motors, SAP, RTX, Lockheed Martin, Starbucks, Royal Caribbean Cruises, Kimberly-Clark, and Qorvo.

Boeing was up 0.3% in premarket trading ahead offourth-quarter earningsfrom the aerospace giant. Boeing pre-announced earnings last week, saying it would post a fourth-quarter loss of $5.46 a share, wider than analysts’ estimates that had called for a loss of $1.55, stemming primarily from a two-month labor strike and costs from job cuts announced last year. The company also said revenue would be $15.2 billion, below expectations of $16.6 billion and down from $22 billion a year earlier.

Shares of auto maker GM rose 0.7%. Wall Street expects General Motors to report fourth-quarter earnings of $1.85 a share, up from $1.24 a year earlier, on revenue of $45 billion, up from $43 billion.
