I'm 36 yr old single male. Just recently bought my first house. Put 20% down on 100K house. Recently (last 18months) my income has tripled and I am finding that I have a lot of cash and not sure where to go with it. I opened up some Vanguard mutual funds. I contribute to my companies 401K. I am putting all my investments into stocks at this point. I have a very high tolerance for volatility. High risk=High reward is ok with me. Any ideas on any aggressive stocks or funds to get into. Have only about $5k to utilize right now.
