possibly..I was guessing today would be a down day(at least early) as anyone who was a buyer of USSSE would have bought in by yesterday to get the divy. The sellers are people who bought in(or more likely bought more) just for the divy and sold today knowing the settlement date would be after Dec 1. Thus the early selling pressure.
The problem is.. shareholders just might have to hold until the pay out date(unknown at this time)...so those sellers today would not get the divy shares.
