This is something I've been noodling around with for a bit. It started out as just something I was curious about and I found the results a little surprising. If others are interested in these I might be persuaded to post this on a semi-regular basis.
I run this once a day, usually between 5pm and 6pm Pacific time. The columns are (in order):
The date - The average price of all active movie stocks - The number of active movie stocks - The cost to go "All In" on movies (100K shares of every MS).
