There's a fundamental change happening with investors: They're putting everything into index funds, CNBC's Jim Cramer said Tuesday.
At the Berkshire Hathaway annual shareholder meeting on Saturday, Buffett told investors they should stick to using index funds, saying they are better off. Buffett offered a negative view of actively managed funds, citing high fees and bad results for investors.
"And Warren Buffett says just keep contributing to your 401(k), just keep buying the index fund. I'm not saying that that is a complacent thing. I'm saying that's become kind of the way people save," Cramer said.
Cramer made his comments on the day the CBOE volatility index (VIX), widely considered the best gauge of fear in the market, hit its lowest since December 2006.
An index fund is a type of mutual fund with a portfolio constructed to track the components of a market index.
