54% chance to have made money if you bet on any of these exclusively from IPO. That's a good reason to diversify over everything, or better yet, wait and then go with the ones who've increased investor value over the past two years. Investment in individual stocks, especially startups, is significantly risky otherwise. It's good that some gamble enough to support on an individual basis though- without them putting their necks out on the line, very few would be in this list.
