I'm a senior in high school. right now i'm playing the stock market game online through my business classes. we're given $100,000 dollars to invest in any companies we choose. I've bought many shares in Goldman Sachs (GS). If you have any suggestions to companies that would be a good investment I would appreciate it, I have about a month or so left of the game. Just looking for some good ways to invest and hopefully come out on top. Thanks!
