US Stocks Suffer Worst Day Since July Amid Inflation Concerns
The S&P 500 and Nasdaq experienced significant drops as inflation data fueled expectations of interest rate hikes.
Major U.S. stock indexes closed lower on Wednesday, with the S&P 500 experiencing its most significant decline since July. The S&P 500 fell 1.1%, marking its fifth loss in the past six trading days. The Nasdaq composite saw a steeper decline, dropping 1.9%, while the Dow Jones Industrial Average slipped 0.1%.
These market movements followed a report indicating that inflation accelerated last month. Wall Street analysts interpreted the inflation data as a signal that the Federal Reserve may increase interest rates. Concerns arose that higher borrowing costs could impede the expansion of artificial intelligence data centers, contributing to a sell-off in AI-related stocks, which were among the market's heaviest weights.
In addition to broader market pressures, Bank of America's stock declined after the company reported lower profits than analysts had projected.
