i have noticed a ton of the trip 0 stocks getting the 2 billion volume in a day situation going on.  of the ones ive seen it in, none have really done anything but buzz for a few days and go back to no bid or back where they were.  anyone have any idea what thats about?  i would be weary of jumping on a ship because of an out of the blue 2.2billion day. it happened to atyg, and atyg went back to no bid in a week after peaking at .0004
