Dow Falls 524 Points on Inflation News 

The Dow Jones index fell 524 points Tuesday, erasing nearly half its gains this year in its worst plunge in 11 months. The selloff was triggered by a higher-than-expected inflation report.

The Labor Department Tuesday morning announced that prices climbed 0.3% last month, or up 3.1% from this time last year. That was higher than expected and enough to push investors to question whether the Fed might delay interest rate cuts.

The S&P 500 was hit with heavy selling too, with nearly 90% of stocks there affected as the index dropped 1.4%.
