I am 23 and about to start graduate school this Fall (Master's program). Since graduating last December with my B.S., I have been working full-time at a software company. It's allowed me to save a little extra money; money that I do not plan on spending during grad school that I can use to invest (~$5,000).
The problem is, I don't know the first thing about investing. I'm pretty open to all options, but I don't know if I should buy stocks, a CD, mutual funds, or if I should go ahead and start a retirement account, based on my age and the amount of money I currently have to invest.
I've noticed a few Ask HN threads about financial advice, and was wondering if anyone had any opinions on the matter based on previous experience, expertise, etc.
Thanks in advance!
