What would be the catalyst for that? You assume that it would be beneficial to just about everyone for the price to go off at the highest pps.
Personally, I know if I was trying to sell my shares I'd love to get more then I was requesting.
My mind is a bit fuzzy this morning since I haven't had any coffee but would that indicate some moderate shorting going on? Nobody else would benefit from consistently filling bid slaps to lower the price like that... I'm also not a MM and lord knows what they think really.
