Exactly four years ago today — on May 18, 2012 — the world was able to trade Facebook shares for the first time as a public company. The company has performed like gangbusters, gaining 215 percent since then.
The interesting thing about this amazing performance is that it's been beaten by plenty of other companies in the same time frame. Whether compared with other firms in the S&P 500, or other initial public offerings from 2012, Facebook loses out to at least 10 companies each time.
