You know full well that trades entered before the close can complete after the close. Period, end of story. Have enough of them stacked up right at the close and it could take a while to print them. Nothing strange or unusual here, unless perhaps a BUNCH of longs decided at 3:59:50 to not carry this burden any longer.
i don't know gump....but my neck is sore from trying to keep up with the billions rolling by....my pupils have cmkx etched in them permanently!
the only time i have seen this happen before was with PCBM...the billions came outta nowhere! rolled by all day long so i figured wth and bought some....shortly after that the co announced a new name and it had a run to .0005 or so. i sold and made a little on it....then later it folded.
if your short theory is correct then we just might see something happen soon...if not correct we will probably see something else happen soon..lol
