I'm doing the same simulation and currently ranked 3rd at my university. My best advice is to gamble and utilize all your trades. Don't wait for some magical stock to suddenly increase in value. Short stocks that you know are bound to drop (ie ANF) and do it a lot. I put a lot of money in British Pound Futures and Gold Commodities before they rose. It's a game, so you want to go for the max return possible. In real life, your return would match your risk tolerance and how you wanted to invest. For only such a short term period and to maximize your returns, most of your trades will be a gamble and at best speculative IMO.
