U.S. markets showed little movement early Tuesday as investors awaited a wave of corporate earnings reports. Futures for the S&P 500, Dow Jones Industrial Average, and Nasdaq were largely unchanged before the opening bell.

General Motors surged over 9% after lowering its full-year tariff impact estimate and raising its adjusted earnings forecast. Coca-Cola shares rose 3.1% following stronger-than-expected sales and profit, aided by a 6% price increase during the quarter. Netflix and Mattel are scheduled to report after the market closes Tuesday, while Tesla reports Wednesday.

Analysts note that corporate profits are under scrutiny following a 35% rally in the S&P 500 since April, with investors watching for signs of sustainable earnings growth amid concerns over elevated stock valuations. Earnings reports are also gaining attention as key U.S. economic data has been delayed by the government shutdown, complicating the Federal Reserve’s assessment of inflation and the job market. The Commerce Department will release consumer price data Friday, marking the first government report since the shutdown began Oct. 1.

Global markets were mostly higher. Japan’s Nikkei 225 edged up 0.3% as Sanae Takaichi became the country’s first female prime minister. Germany’s DAX gained 0.2%, France’s CAC 40 rose 0.5%, and Britain’s FTSE 100 advanced 0.3%. Asian markets also saw gains, including Hong Kong’s Hang Seng (+0.7%) and Shanghai Composite (+1.4%). U.S. crude rose 32 cents to $57.54 per barrel, while Brent crude increased 30 cents to $61.31. The euro slipped to $1.1619 from $1.1641.
