I am not a fan of investing games and contests. Here are my reasons:
Here’s what I can endorse, if done fairly: paper-trading. As with any sort of self study, if you want it to be valuable, you have to be a strict cop on yourself. I papertraded a number of times in the 80s, and I always did well vs the market. My porfolios typically had 40-60 companies, but they always did well. As a TA in Corporate Financial Management, I would share my ideas with students, who liked my enthusiasm. The professor was a EMH devotee, who when he heard that my paper portfolio was up 40% while the broad market was up 20%, said, “Oh, you pick stocks that have a beta of two.” I tried to show him that was not the case, but “you can’t teach a Sneech.”
Paper-trading moves at the speed of the market. It is close to real. It shows you how difficult it is to make money. I recommend it to all of my readers.
