Garden we all know stock players are out there and you can't really do anything about that. As investor, you learn to see these patterns and what's important is you ride the ride and not chasing any stock that pops on news. Whatever is cooking behind the scene, as long as it pops at the right time and as long as you benefit from it, you win.
