what are you talking about that many shares. you mean generaly the amount of vol in past two days or a specific big block that went through. either way its not just one person its the entire 45m float that is profit taking, actually about 15m held and 30m sold, most likely. you have to realize that 45m shares gained over 100% value from fridays low to monday. i would expect a minimum of half to take profit. they will comeback though no way they wont buyback. if it were a co. with no attention and out of no where it gets a pr like it got then yes i could see it fly 1-2-3 bucks that day but because most of the float that day doesnt know its happening and wont get in the way of the buying pressure. in the case of acmg it is very popular and known by all .pk investors. so when a news hits for it there will be resistance on the way up because everyone is prepared to sell for profit. you would have to agree that 99% of the 45m float was prepared for this week.
