World shares retreat after losses for Big Tech pull US stocks lower

World shares retreat after losses for Big Tech pull US stocks lower Updated 11 mins ago Shares in Europe and Asia have retreated following a broad decline on Wall Street spurred by selling of Big Tech shares. But benchmarks in Asia recovered much of the ground lost earlier in the day, when Tokyo's Nikkei fell nearly 5%. It closed 2.5% lower. U.S. futures were mixed and oil prices fell. On Tuesday, declines for the same big tech companies that have been the main drivers of the markets' rally so far this year pulled the S&P 500 down 1.2%. The Dow lost 0.5% and the tech-heavy Nasdaq composite fell 2%. Palantir Technologies slumped 7.9% despite reporting results that beat analysts' forecasts. Nvidia also reversed course, with a loss of 4%.
