No stock can drfy gravity unless it has unbelieveable growth potential. PCLN has crashed GMCR has crashed, NFLX has crashed ZNGA and FB also, GRPN from 150 to 30. AMZN and LNKD will also suffer the same fate when growth slows to a reasonable PE multiple 15-25
The went down a few days after lockup, but then rallied for a LONG time after that. You shorts saying FB is gonna go down to 10 or even 5 within a few weeks might be in for a surprise. LNKD didn't do anything like that.
