In the following video, contributor John Reeves gives us his take on three of the biggest movers this week. He tells us about the continuing tug-of-war over Herbalife (NYSE:HLF) that has left the stock up 9% this week, and tells us why he doesn't see much of an edge in this for retail investors. He also talks about Denbury Resources (NYSE:DNR), a company specializing in enhanced oil recovery, which was up 8% for the week on news of its purchasing properties from ConocoPhillips (NYSE:COP), which will mean more production for Denbury down the road. And finally, he discusses Fusion-io (UNKNOWN:FIO.DL), the disruptive data storage company up 9% this week on news of a new product line called ioScale.
