In this video, Motley Fool tech and telecom analyst Eric Bleeker takes a look at some tech jumps that were surprising for many today: Groupon (NASDAQ: GRPN), Facebook (NASDAQ: FB), and Zynga (NASDAQ: ZNGA). These are three companies that investors have been wary of for a long time now after they IPO'ed at what many thought were large overvaluations, after which all three stocks subsequently fell hard, with many citing untested business models. Eric takes us through some of the things that have restored some investor confidence recently.
