[U.S. stocks’ “AI trading” this week may face a test of the performance of companies such as Meta] October 19th: After last week’s sharp decline in chip stocks, the U.S. stock market is expected to recover some of its lost ground, which is expected to usher in a positive start to the week. This week’s corporate financial reports are expected to put artificial intelligence (AI) themed trading to another test. Meta’s financial report released this week will be a new test of investor confidence in AI trading, and Tesla will also release results. The sector has suffered heavy setbacks recently, and the market is concerned about whether related companies can maintain rapid profit growth while continuing to support an investment boom that increasingly relies on high-cost debt financing.
