Talking with someone who has played the MM game. When we traded with low volume for most of early afternoon above 45's and then took the quick plunge into 43's he said it looked like an MM move to clean out stops.
In other words MM sees bunch a stops below trading range and when volume gets REAL low they stop buying. This causes price to fall some, hits some stops and BANG. Get a domino effect knocking out more stops.
Why? The MM then goes in and buys cheap shares before price recovers.
If you can't accept that MM's manipulate stock prices, then perhaps *you* need a bit of growing up to do. RDWR appears to be one of the most manipulated stocks I've seen lately.
