On the 23rd, the U.S. tech stock sector took a nosedive, influenced by the escalating situation in the Middle East and investor concerns about the return on investment in artificial intelligence (AI). The "Magnificent Seven" index plummeted by 4.8% in a single day, wiping out $797 billion in market value—the largest one-day decline since April 2025—and pulling down the three major stock indices of the New York Stock Exchange.
The immediate trigger for this round of market adjustments was the earnings reports and capital expenditure plans released by major tech companies. Alphabet, for instance, raised its capital expenditure forecast for 2026, signaling continued heavy investment. Meanwhile, Tesla reported second-quarter profits that fell short of expectations, compounded by significant capital expenditures this year. These developments led to respective stock price drops of 7.1% for Alphabet and 15% for Tesla. Other tech giants, including Microsoft, Amazon, and Meta, also saw their stock prices decline.
Market analysts have highlighted a growing contradiction between the aggressive investments in AI infrastructure by tech companies and the uncertainty surrounding the monetization cycle of these investments. This tension, coupled with external factors such as the U.S.-Iran conflict driving up oil prices, has intensified downward pressure on the market.
Currently, the "Magnificent Seven" index has dropped 11% from its historic high reached in late May this year, resulting in a market value erosion of $2 trillion. In the short term, the tech sector is expected to continue grappling with valuation corrections and increased market volatility.
