Stock Market Gains on Inflation Relief; Tech Stocks Rally as Semiconductor Volatility Eases
US stock markets rose on Wednesday as better-than-expected inflation data boosted investor sentiment, with the S&P 500, Nasdaq, and Dow all finishing higher. Tech megacaps like Apple, Amazon, and Microsoft led gains, though semiconductor stocks showed mixed performance amid ongoing AI spending concerns.
Markets Rally on Cooler Inflation Data
The S&P 500 rose on Wednesday, with major technology stocks advancing, as traders digested more data showing inflation is cooling. The broad market index finished up 0.38% at 7,572.40, while the Nasdaq Composite climbed 0.62% to settle at 26,269.23, and the Dow Jones Industrial Average added 150.37 points, or 0.29%, to end at 52,658.64.
Technology Megacaps Lead the Advance
Amazon and Alphabet moved up around 3%, while Microsoft was higher by nearly 3%, and Apple gained 4%, hitting a new all-time high. The Nasdaq saw best performance on the day, rising to 26,269.23, buoyed by megacaps like Apple (+4.01%), Alphabet (+3.17%), Meta (+3.07%), Amazon (+3.02%), and Microsoft (+2.78%). Investors rotated capital into large-cap technology names as inflation concerns eased.
Mixed Signals in Semiconductor Sector
Among the chipmakers, Micron Technology shares declined 8%, while Lam Research shares were down 3%, as were those of Advanced Micro Devices. Semiconductor stocks are swinging more dramatically than at any point since the early pandemic period, illustrating how choppy the market's favorite AI trade has become, with the iShares Semiconductor ETF up more than 3% and the 50-day rolling standard deviation of daily returns for SOXX climbing to 4.2%, its highest level since May 2020.
Broader Economic Signals Mixed
U.S. equity markets closed higher on Wednesday following a producer price index (PPI) report that came in below expectations for June. Stocks were climbing, boosted by technology stocks and better-than-expected inflation data. The market response reflects investor relief on the inflation front, though ongoing volatility in key sectors suggests caution about the sustainability of the rally.
