The good news: I'm several months out of college, working at a fun, well-paying job, and debt-free. My spending is pretty low.
The more difficult news: Beyond maxing out my 401K contributions (up to the full 17% - my company offers a Roth 401K which is simpler than starting an IRA), I've no idea where to start investing. I don't want to lock up all my money for the long term, in case I get married / buy a house / move to a startup in five years or so. (None of those look particularly imminent at the moment, but I want to keep my options open.) But, of course, if none of those happen, I want to be positioned well for financial independence.
So where do I begin? I was looking into money market mutual funds, but I couldn't find any which've been performing higher than the credit union savings account I'm currently stashing money in. Are basic mutual funds the place to go, even for the money I want available in ~5 years? And where would you recommend starting?
