When you have that little savings, the best investment you can do is in yourself, i.e. increasing your earning power. Not worth dealing with stocks under $50k IMO.
ETA: Stocks give a false sense of "compound interest", growing capital, but the truth is under 50k you'll make negligible interest for the hassle. Working harder is literally easier and gives a better bang for your buck (time). I started investing around 80k, now at 470k, and my returns are starting to be worth the time.
