Because the shorts might have gotten wind of successful 10K(I believe just as the FDA has moles, so to does DT) and they would have pulled out all the stops just like they do when they are on the wrong side of FDA approvals.
By the release of hit pieces we received over the weekend and the trading at the start of Friday it was clear that they intended to spread more FUD, and it was probably going to be their make or break day for getting us under $10. If they managed to get us under $10 a big psychological barrier would have been broken and they would have been able to escape IMO.
So CCME halts the stock citing a possible leak of the results, they finish up everything with DT over the weekend and now they deceive the shorts into thinking they've won until the 16th. The shorts won't be able slip away, they'll be facing a huge gap up and find very little people willing to sell for less than $30.
