The sell off is a carefully orchestrated plan by the Hedge funds that are incurring substantial losses in this stock. They can short unlimited shares, but since the company is doing so well selling their Crocs & expanding their market lineup, the Hedge funds are having a hard time off setting all the buying. Therefore look for short concentrated bursts of selling that drive the market down substantially. I like to buy on these dips because usually there is such a fast snap back it can give us whiplash.
Hold on though, it will be a wild ride. In the end the fundamentals of the company win out over any kind of manipulation or rumor.
