well, generally the the prices aren't that much more helpful than the predictions put out by the movie sights. Collateral is priced at 86 bucks right now, divided by 2.8, is a prediction of a 30.9 million opener. The studio tracking is in the lower 20's. I'm shorting it. Little Black Book is priced at 26, meaning it's priced for a 9.4 million weekend, right where the line is. I'm shorting that one as well. It's really sporadic, sometimes the price is just around right, usually it's a bit too high or too low, sometimes it's way off. Someone said that if you longed every opener last year you'd be up just over a million bucks, that's it. I do take into account the stock price of a movie when attempting to cap it.
