U.S. stock futures declined on Wednesday as disappointing earnings reports from major tech companies dampened investor sentiment. In after-hours trading, Super Micro Computer dropped more than 13% following weaker-than-expected quarterly results, leading to declines in other chipmakers such as Nvidia (-2.6%) and AMD (-1.6%). Airbnb also fell nearly 17% due to disappointing second-quarter results. During regular trading on Tuesday, the Dow rose by 0.76%, the S&P 500 by 1.04%, and the Nasdaq Composite by 1.03%, with all 11 sectors of the S&P closing higher. These gains followed a sharp sell-off on Monday driven by recession fears in the U.S. and the unwinding of yen carry trades. Among individual stocks, Palantir Technologies surged by 10.4%, beating analysts' estimates, Uber jumped by 10.9% after better-than-expected second-quarter results, and Caterpillar gained 3% after reporting earnings that exceeded Wall Street forecasts.
