AI Stocks Are in a Bubble, Most Investors Say in BofA Survey

A record share of global fund managers said artificial intelligence stocks are in a bubble following a torrid rally this year, according to a survey by Bank of America Corp.

About 54% of participants in the October poll indicated tech stocks were looking too expensive, an about-turn from last month when nearly half had dismissed those concerns. Fears that global stocks were overvalued also hit a peak in the latest survey.
