Overpriced stocks can drop any time for any reason. That's the risk you take. In this case it might be THQI's earnings miss because of Full Spectrum and the expectation that Godfather may result in a miss for ERTS. Or it could be anything at all really, given the valuation.
"Jesterbunk did you short this too? Any signs of tech_stock_hero over here?"
I'd be playing this both sides and short term in the 50-60 range. It's expensive enough that I don't see it going much higher in the near term, and it's too good a company with too good management to go much lower.
tech_stock_hero seems to have magically and suddenly disappeared. Very convenient.
