U.S. stock futures inched up slightly on Thursday, as futures contracts for the three principal indices rose by approximately 0.1%. This comes after a technology-driven sell-off that led the S&P 500 to experience a second day of consecutive losses and wiped out the Nasdaq 100's gains for the year, now showing signs of stabilization. Nonetheless, apprehensions about disruptions related to artificial intelligence and heightened valuations continue to linger. In premarket trading, Nvidia rose by 0.6%, Broadcom by 2.5%, and AMD by 0.7%. In contrast, Alphabet fell by 2.8% after it disclosed significant increased spending on AI for the year, despite surpassing earnings and revenue forecasts. Qualcomm dropped nearly 12% following the release of a disappointing forecast. Amazon saw a slight decline of 0.1% ahead of its earnings report scheduled to be released after the market closes today. Other major companies such as Microsoft (-1.6%), Apple (-0.2%), Meta (-0.3%), and Tesla (-0.6%) were also trading lower.
