Stocks? Bonds? Real estate? Forget it. Young adults would rather keep their savings in cash.

According to Bankrate.com‘s most recent Financial Security Index, 39 percent of Millennials—people between the ages of 18 and 29—prefer to keep their savings pretty liquid, as opposed to investing in the Stock Market or sinking it into another opportunity. This worries some investment experts, who believe Millennials will sail into their golden years without much more than a high-interest credit card.

“These findings are troubling because Millennials need the returns of stocks to meet their retirement goals,” says Greg McBride, a financial analyst with Bankrate.com. “They need to rethink the level of risk they need to take.”

Given the state of the stock market during the past decade, perhaps it’s not so surprising that young adults would be leery of socking away their hard-earned cash in the stock market, but deeper analysis suggests Millennials would invest more…if they had steady jobs with 401k accounts. As it is, they often don’t make enough to invest. (Time)
