Microsoft Corp. and Meta Platforms Inc. have led a surge in Wall Street, driven by strong performances in their respective sectors. Microsoft's stock rallied 7.6% after reporting a 13% increase in overall revenue, attributed to robust growth in its cloud computing and artificial intelligence businesses. Meta, the parent company of Facebook and Instagram, saw its stock climb 4.2% following a report that its AI tools boosted advertising revenue, surpassing analysts' expectations for both revenue and profit in the latest quarter. In contrast, Nvidia Corp. has faced challenges, leading a decline among the 'Magnificent Seven' tech stocks. Nvidia's stock fell 1.5%, the most significant drop among the group, amid uncertainties related to U.S. export controls on its AI chips to China. The company has been adjusting its chip designs to comply with these restrictions, aiming to continue serving the Chinese market, with CEO Jensen Huang communicating with major Chinese companies like ByteDance, Alibaba, and Tencent. However, these adjustments have not prevented a cooling in the tech sector, with the Nasdaq 100 futures falling 0.9% after a 3.5% gain in the previous four sessions. The broader market has been influenced by these developments, with the S&P 500 rising 0.6% for its eighth consecutive gain, while the Dow Jones Industrial Average added 83 points. The performance of tech stocks, particularly Microsoft and Meta, has been pivotal in driving these gains, highlighting the sector's significant impact on overall market trends. Meanwhile, Huawei is preparing to ship its advanced AI chip, the 910C, to Chinese customers, potentially impacting Nvidia's market position further.
