a couple things about MM's.. no matter how many MM's there are, there are usually 1 or two that most of the trades will go through. Most brokerage firms have working agreements with certain market makers, or will consistantly go to the same MM because they fill the order, no questions asked.
most MM'sjust trade #'s and dont care what the company does, or what rumors are, they go long when they see the first signs of heavy sustained buying, and might go short when that dries up.
Hedgies are a different story.
