Don't stocks go down when people are shorting a stock? I believe that is what is going on now. If it is true what White is saying and Jamba wil have positive same store sales these same shorts are going to have to cover when the squeeze upward begins.
They have been covering for the last week or so but some will still hold the short. Especially someone with a huge long position, they can short the stock to protect themselves marginally and hold the short until it gets back to where they started from. Should news be bad they are in good shape and if it is good news they cover and re buy in and enjoy the ride back up.
