For a contest to see who can make the most on one month, I'd go with penny stocks. Pick one, go all in and hope.

invest it in your mom

I'm taking a business class in Alberta and we are doing a stock challenge for one month. Whoever makes the most money wins. It starts on Tuesday, and I have no idea what to invest in. We have $100,000 plus an optional $50,000 loan with 8% interest. Can anyone point me in the right direction or name some stocks that could make me a profit in a month??
