in horse racing ( a big gambling sport i might add) theres a term called "Bridge Jumping" its whenever theres a small field and one of the horses towers over the competition...the bettor will place 10's and 100's of thousands of dollars on the horse to show (1st, 2nd, or 3rd....if that horse wins they generally collect .10 on every bet. 100,000 dollars bet would only net about 5,000....
im telling you this because....Why wouldnt someone come in and scoop up 20 or say 30 million shares and then dump them within hours or days of getting them? profit it profit....
again i merely feel its just herd money...some folks in the herd bet big....some folks in the herd bet small...
