RE:50 k at 3.88Brioche, you may want to check rules associated with stock buybacks. From my memory, they can't buy first nor last half hour of day, they are limited to a certain percent of trailing 30 day volume and can't buy offers nor raise bid. They can match bid but not move bid up. So they are handcuffed as to how many shares they can buy daily unless things are different now.
