Stocks Edge Higher Amid Trump Tariff Uncertainty

Stocks inched higher in early trading on Tuesday, as the Trump administration’s chaotic tariff rollout continues to spur volatility in the markets.

The S&P 500 opened up 0.5 percent, and the technology-heavy Nasdaq also gained slightly. President Trump’s whipsawing tariff policies are still driving sentiment on Wall Street, especially in sectors facing the threat of more levies or potential reprieves.

Here’s what else to know:

• Bank stocks rose on Tuesday, as major U.S. lenders reported their latest earnings. Bank of America surpassed Wall Street’s profit and revenue expectations, and its shares rose about 5 percent Tuesday morning. Citigroup’s profits also beat estimates, sending its stock more than 2 percent higher.

• Tariff threats are taking center stage in the pharmaceutical and technology sectors, after the Trump administration on Monday took steps that appeared likely to result in new tariffs on pharma products and semiconductors. Shares in drugmaker Eli Lilly were up slightly on Tuesday morning, while Novartis stock was trading roughly flat. Shares in chip giant Nvidia were nearly 2 percent higher, after the company on Monday said it would invest in artificial intelligence infrastructure in the United States.

• Shares in Boeing, the aviation giant, fell about 1.5 percent on Tuesday following a report from Bloomberg News that China had instructed its airlines to halt deliveries of Boeing planes after the Trump administration imposed steep tariffs on Chinese goods.

• In the auto industry, shares in General Motors, Ford Motor and Stellantis — which jumped on Monday after Mr. Trump signaled that he might offer car companies some relief from tariffs — were mixed on Tuesday morning. Shares in General Motors and Ford both fell more than 1 percent, while Stellantis rose about a half percent. The sector, which is grappling with a 25 percent tariff on imported vehicles, is bracing for new levies on imported car parts.

• The U.S. dollar, long a haven in global financial markets, has been falling against other major currencies. But an index that tracks the currency against a basket of major trading partners stabilized early Tuesday, ending a five-day slide.
