Is This Popular Investment a Smart Choice for Your 401(k)?

If you have access to a 401(k) plan, you have a prime opportunity to save well for retirement. That's because 401(k)s come with generous annual contribution limits. And also, many employers that sponsor these plans match worker contributions to varying degrees. Contribute enough money out of your own paycheck, and you may be in line for a bundle of free cash.

But the money in your 401(k) shouldn't just sit there doing nothing. If you want your retirement savings to grow, you'll need to invest that money. And target date funds are a popular means of doing just that.
