So the approach that I took was to buy as many shares of stock as I could in the beginning rounds, before the price rose. Then I waited as watched the price rose, knowing that my competition would want to buy and then sell with the presumption that the price would continue to rise. So just at the right moment I sold all of my shares. Other technical things went on, but I am proud to say that (aside from the teacher) I was number two in all of the class at the end of the game and subsequently got my name put in a drawing for a Starbucks card.
That class experience, combined with an extra hour of curfew all formulated to make a very memorable and distinct first Friday at Brown.
