Well think about it for a sec . A trader wouldn't chase the pps down trying to sell when the chart keeps bouncing back down off the wall , they would pull the order and sell at stages on the way up in smaller blocks . They need momo too . It's a mm keeping a cap on it or a lender just takeing what ever they can get right now . Someone posted that it could be a cap on pps to secure a buyout bid .....very possible IMO as apple , Google , and Microsoft are buying lil companies left and right . It's a real battle and soon I think zynga will buy lil companies as well , they are pushing to get more Mobil ya know .
