either the specialist is sleeping, doesn't care or blatently allowing manipulation in trades...today, a 200 share sale took the stock down over 50 cents?? c.mon...being reported to the sec for review..
Well, if someone had a BUY order in at a LIMIT price 50 cents less than prior trade, , and someone else put a MARKET order in to sell, and there were no other BUY orders at the moment, that would probably do it. Can you explain what the alleged manipulation would be and what the concern is, other the someone placing a market order on a stock that wasn't very active at the moment? ?
