Microsoft's stock has worst day in two years after disappointing forecast

Microsoft's better-than-expected earnings report wasn't enough to prevent the stock's steepest sell-off in two years, as investors instead focused on the company's forecast for the current period.

Microsoft shares fell 6% on Thursday and headed for their worst day since Oct. 26, 2022, when they dropped 7.7%. That was a month before the public release of ChatGPT from Microsoft-backed OpenAI, a launch that set the stage for a boom in artificial intelligence investments.
