If you’ve ever heard someone say “I’m building my portfolio,” you might picture a folder full of stock charts or a Wall Street professional in a suit. But here’s the truth: an investment portfolio is simply a collection of things you own that are meant to grow your money over time.

If you’ve just started contributing to a 401(k) —or you’re thinking about it—you’re already ahead of the game. But how do you know if your money is working hard enough for you? 

That’s a loaded question.  “How rich do you want to be later in life?” is a better way to ask the question.
