Hello everyone! My class to doing a simulation on Marketwatch.com, which will last for 80 days or less. So I was wondering, in order to have the best chance of succeeding in the simulation, what are the best short term investments to make in the game over the holidays and into 2018?

I currently have 38k to invest in the simulation.

(I know this isn't like real money investing, but eh, I want to win the simulation and maybe gain some good info in the process! Thank you!)
