The first note I have on this one is noticing it when it made a new 52 week high in the week ending 10/26/2012. I also wrote that it's volume was increasing and the week was an overall crappy week in the market. It retreated fairly hard in November dropping down to 12, so I almost threw it out of my buy watch. However, it recovered to new highs and I bought it on Friday at 15.02.
