Well the only thing I can see is the Dominick has 300000 shares to sell so they hit the bid for 41000 shares and they have a client or pro willing to take the balance so they sold 41 thou to clean out the bids then crossed the 259 tho. Happens all the time. With all stocks. Other brokers are not colluding with that . If it was all Dominicks selling iand they were selling thru other brokers it would show as seller being anonymous
