US equities finished mixed on Thursday, with the S&P 500 flat, the Nasdaq 100 falling 0.5%, and the Dow Jones up 0.1%. Investors reassessed their exposure to mega-cap tech stocks while also weighing encouraging economic data. Despite optimism surrounding semiconductors and AI demand, concerns over concentrated gains in a few hyperscale and software names weighed on broader indices. Micron rallied over 15% after stronger-than-expected earnings and a bullish revenue forecast for the August quarter, while Qualcomm rose nearly 4% after doubling its projection for non-handset revenue in the next three years. By contrast, Nvidia, Oracle, Amazon, Alphabet, and Microsoft saw losses up to 3.7%. Apple fell 6.1% after raising prices on MacBook and iPad products, citing higher component costs, including memory chips. Fresh data showed the US economy growing faster than previously estimated and inflation rising in line with expectations, prompting a slight reduction in Fed tightening bets.
