A few weeks ago, I read an article in the Wall Street Journal about people who had opened up their very first investment accounts just to get in on the Facebook IPO. One man they profiled had purchased $10,000 worth of stock, borrowing $5,000 of it from his mother. Clearly, for him, this was a major investment, so it seems likely he felt this was a sure bet. It also seems likely that he’s kicking himself today, as the value of the stock has dropped almost 25% since its May 17 IPO.
