After five minutes of trading, the Dow Jones Industrial Average was up 0.5 percent, while the broad S&P 500 index was down 0.5 percent and the tech-heavy Nasdaq Composite Index fell 1.1 percent.
What is weighing on markets is the harsh September inflation data released earlier this week. This has increased concerns that the US central bank will soon raise its key interest rate.
Several AI-related stocks also opened lower on Thursday. Concerns are spreading that semiconductor and memory chip manufacturers are overvalued and heavily indebted, CNBC writes.
Earlier on Thursday, Asian stock markets, especially in South Korea, closed sharply lower. Here, too, concerns about interest rates and AI companies are dampening investors' willingness to invest.
