The call buys are limited to 20,000 shares meaning each max purchase on the call and on the .OW will move the .OW more than the call. So you get cases like this where the .OW more closely represents the market's opinion on the weekend than the call. If there were more active players prices would be more consistent.
And to your question about Menashe:
There aren't enough players who are active enough for every stock to be accurately priced. There are some players who are active enough to get the gains on basically everything, but most of the regular players don't look at everything because that takes time and effort and this is a game that we want to be fun so we don't want to take the time to look over the whole market.
So this one slipped beneath the radar for all but those few super active players who can't buy enough shares to move the price up to "true value", and thus the price is lower than it probably should be based on the weekend's gross and that it has 4-6 more weekends to run.
But you mentioning it here on the movies board will bring it to more people's attention and so the price will go up here in the next few hours.
This might get scrubbed because I'm talking about the price and not the box office.
