Loaning out ANTS shares. Depends what kind of account he has. Cash can't loan out shares. Margin can. I have 3 margin accounts and 2 stocks have shares loaned out now. One to NITE, one to UBSS. I can change MMs position by punching in a sell and he instantly goes to that place to try to block the sell within a second. When I cancel sell he instantly goes back to where he was within a second.
