Stock markets have performed well lately, giving retirement investors big boosts to their net worth. But a recent study from the Employee Benefit Research Institute found that even with these gains, many workers are still not likely to have enough money to last their lifetimes.

In the following video, Dan Caplinger, The Motley Fool's director of investment planning, looks at the EBRI study and its implications, noting that among baby boomer and Gen X workers alike, more than 40% will likely run out of money if they don't take steps to improve their finances. The study points to the need to maximize Social Security while also protecting against longevity and health risks, and Dan notes how important it is to protect against these risks. With strategies like long-term care insurance and annuities, many investors can boost their chances of outliving their money.
