Shares of Dell and HP fell on Wednesday after the personal computer makers issued forecasts that cast doubt on a market recovery driven by artificial intelligence-enabled PCs.

HP Inc. gave an outlook for profit in the current quarter that fell short of estimates, suggesting a setback in the personal computer market’s recovery from a yearslong slump.

HP forecast its first-quarter profit below Wall Street expectations on Tuesday, signaling persistent choppy demand in the personal computers market and sending the company's shares down 8% in extended trading.
