I think that LinkedIn ( LNKD) is the best of the social media IPOs of the last few years. The firm's professional social network connects more than 130 million users with colleagues who can help them land jobs, fill them, or figure out business problems. >>5 Big Tech Stocks to Trade (or Not) LinkedIn's advantage can be summed up in a sentence: It's the only social network that's actually monetized helping users do what they want to do. While other social media firms earn revenue by distracting their users from what they're trying to do (and getting them to click on ads while stalking their friends, for instance), LNKD makes money by helping users with the exact task they're trying to accomplish: find a job, network or hire someone. That seems like a small distinction, but it's critical to LinkedIn's ability to make money off of each user. Increased job turnover in recent years makes LinkedIn a must-have product, particularly in an environment where traditional job Web sites are being seen as less and less useful. The firm's spotless balance sheet includes $750 in cash and no debt. While this firm is far from a value play, stellar relative strength makes it a good momentum name to watch this quarter.
