As long as housing is recovery and the reports back it up (and earnings especially .... ie. beat and raise) it will continue to rise. It has been doing that for 1 1/2 years. If you are a bullish trader on this company you have done very well as I have. But I agree that you want to sell your calls when it pops. Sold ALL of mine yesterday. I will buy back call on price swings of 5% down or more. Been working for a year. Still holding about 1000 shares of the stock, though.
I was with this company when it was in the 3 range though so if I had a bigger crystal ball I would have made a lot more with better timing.
