US stocks are set to double or triple their recent declines, Jeremy Grantham warned in a CNBC interview this month.

The S&P 500 could tumble another 21% to around 3,300 points, according to a recent MarketWatch article.

The S&P 500's dividend yield has historically correlated with the 10-year Treasury yield before a bear market ends.

He was unsurprised by the sell-off, and compared the recent downturn to the summer of 2008, raising the prospect of a recession.
