U.S. stock markets strengthened their rebound as investor concerns over the disruptive impact of artificial intelligence eased and multiple economic indicators pointed to solid performance in the American economy. Approximately 320 components of the S&P 500 index advanced, even though the latest Federal Reserve meeting minutes revealed that "several" officials suggested the possibility of interest rate hikes if inflation remains persistently above the central bank's target. Following a sell-off in technology stocks triggered by fears about AI's disruptive effects, investors are now searching for signs of a market bottom. The chip stock index rose 1%, while an ETF tracking software companies jumped 1.3%. Paul Stanley of Granite Bay Wealth Management noted that the sell-off in software stocks may have been "overdone," describing it largely as a knee-jerk reaction as investors try to distinguish between potential winners and losers in the AI sector. "While the prospects for AI are very promising, investors should not assume that every company will succeed in the AI space," he commented. As of 4:00 PM New York time, the S&P 500 index was up 0.6% at 6,881.31 points. The Dow Jones Industrial Average rose 0.3% to 49,662.66 points. The Nasdaq Composite Index advanced 0.8% to 22,753.63 points.
