Year end and Q4 earnings will be reported next Friday, 2-22-13. The stock is down 8 bucks in 4 days on above average volume in each of those 4 days. Friday's volume was almost double the norm. All of this is hardly the work of day traders. Stock now below 50 DMA as it failed to get support, triggering even more selling. My guess is that it will take a lot longer than getting to next Friday to turn this ship around. Increasing the dividend by another 50%-100% might do the trick.
I don't think there is anything wrong with how they're performing. I think as soon as they preannounce the profitakers sell off the stock. This stock has 150 written all over it and that can be accomplished with raised guidance next Friday.
