Investors are rightfully fearful of IPOs these days. Facebook (Nasdaq: FB) hit a fresh new low on Friday, leading the market to conclude that early backer Peter Thiel knew what he was doing when he unloaded most of his shares a week earlier.

He's not alone. Dustin Moskovitz, Mark Zuckerberg's Harvard roommate and Facebook's original CTO, began to sell some of his shares a few days ago. This is why investors fear when lockup restrictions expire a few months after a company goes public, freeing insiders and early investors to cash out of sizable stakes.

We've seen plenty of companies, particularly dot-coms that are typically generous with stock- and options-based compensation, take big hits at the time of lockup expirations. However, that didn't happen on Wednesday. Restaurant-reviews website Yelp (NYSE: YELP) actually saw its stock pop 22% higher on the day its lockup restrictions went away.

The lesson to investors is that there is no such thing as a slam dunk when it comes to investing. Shorting a stock ahead of lockup expirations may seem like a good idea, but sometimes the pessimism is too thick. Sometimes investors bail early. Sometimes stocks bounce back on the unlikeliest of days.
