Shares are mixed in Asia after the worst day for Nvidia’s stock since last spring dragged the U.S. market lower. U.S. futures fell as investors focused on comments by Block CEO Jack Dorsey on his company's decision to lay off 40% of its workforce because of labor-saving artificial intelligence. On Thursday, the S&P 500 fell 0.5% and the Dow Jones Industrial Average added just 17 points. The Nasdaq composite sank 1.2%. Despite a stellar profit report, Nvidia's stock had their worst day since April.
