DETROIT (Reuters) -General Motors on Tuesday posted fourth-quarter 2024 results and a 2025 earnings forecast ahead of Wall Street expectations, but shares fell sharply in trading Tuesday as investors weighed the threat of tariffs that could hit the automaker's business. GM is one of the automakers most exposed to Trump's plans on two important fronts: EVs, where it has made aggressive investments, and tariffs, because it has substantial manufacturing in Mexico and Canada, countries that Trump is targeting.

Synchrony Financial's fourth-quarter profit and revenue came up short of forecasts on higher costs and less-than-expected net interest income.

As a tech stock rout and U.S. dollar swings driven by President Donald Trump's tariff threats send markets into a tailspin, investors are piling into assets from Japan's yen to European credit that could act as a buffer to the turbulence. Markets that cheered Trump's pro-growth agenda have turned bumpy, with oil prices and Canada and Mexico's currencies gyrating, muddled inflation forecasts shaking Treasuries and investors starting to view the new White House as a source of risk. "There will likely be more volatility in the U.S. dollar and across many other assets," said Amelie Derambure, senior multi-asset manager at Europe's biggest investor Amundi.

Hedge fund manager Bridgewater Associates said Chinese startup DeepSeek's launch of its latest artificial intelligence (AI) models could lead to a short-term correction in many tech companies' share prices but is positive for the industry. The comments come amid a tech stocks sell-off prompted by the release of a free AI assistant launched by DeepSeek last week that the startup said uses less data at a fraction of the cost of services currently available. DeepSeek's AI Assistant has overtaken rival ChatGPT to become the top-rated free application available on Apple's App Store in the United States, raising doubts about the reasoning behind some U.S. tech companies' decision to pledge billions of dollars in AI investment.
