So Friday at the close the price was 33.52 and then about 4:16 a 5M block traded at 33.70 and after that the posted close was 33.70 even though it traded back in the 33.5x's Then on Monday it closed at 33.58 and same thing happened - a large trade went thru at 33.80 after 4:15 and it traded back near the close. 33.80 was the official last close on Yahoo and my broker. Charts show the move up if you look. Are these market on close orders ? Kinda fubared that the pps shows red all day when it is really up from the previous day. Some sort of psycholgical trading warfare here ? Any insights ?
