OK, I've been tracking/stalking this one listed stock. Its a steady, liquid stock that's been holding up pretty well. But in the past few days, I've noticed at literally the last second (say within 15secs of closing) that there's a spike and big ass block print of 20000 shares (big and unusual for this stock). Its been holding up pretty well in the negative stock environment we're in right now, but every time this happens, it guarantees that the stock will see green. Volume's moderate, it sees +500K a day, but its been pretty light this past week (after a rather extensive bull run, sort of in the pause and refresh phase or possible reversal, you never know), easily drifiting into the negative during the doldrum hours of the market. Anyways, any ideas? Is some insitution just snatching up shares at the EOD? Window dressing? OK, on a similar topic, what kind of games have you noticed MMs and Specialists playing? Got any personal stories where you were faked out by MM/S or knew exactly what he was doing and just shadowed him?
