Jeremy Grantham: The Most Expensive Market in American History 6/26/26

Investing legend Jeremy Grantham founded one of the first index funds in the 1970s, and in a special Squawk interview, he’s issuing a warning to investors. A permabear, Grantham expects a market decline of 70%, and he’s counseling his team to avoid U.S. stocks. Plus, OpenAI may wait until 2027 to IPO, and Apple is hiking product prices, thanks to rising costs of memory chips.
