The stock is 25% off its 52-week high. And, the majority of CWH investors probably acquired their shares at a higher price than the current market price. This is the last trading day of 2012. On January 2nd, tax-loss selling will abate, which should spur at least a small rebound in the share price during the first quarter.
You forgot the most important thing for CWH this January. It was a big loser in 2012 (another great and consistent underperformance), but many folks - particularly the more affluent among us - stalled their tax loss selling into this year. They will probably sell and book the loses over the next few weeks.
So, expect a real poor January for CWH and for it to lag the market (which it is excellent at doing!).
