On Thursday, ahead of the Federal Reserve's March meeting, stock market futures initially gained, driven by anticipation of key economic data releases, including inflation and retail sales figures. However, the mood on Wall Street shifted dramatically on Friday after the release of hotter-than-expected inflation data, which led to a tumble in U.S. stocks as bond yields surged. The inflation data, which came in higher than forecasts, spooked investors, capping gains and fueling concerns over the Federal Reserve's next moves. This sentiment was reflected across various sectors, with technology-related megacaps, which have been at the forefront of this year's rally, experiencing significant declines. US futures tread water after more hotter-than-expected inflation, underscoring the high level of investor sensitivity to inflation indicators and their potential impact on the Federal Reserve's interest rate decisions.
