DTEA is also, I believe, looking for a new CEO. They may not want to establish new corporate directions until that person is on board and part of the commitment to new directions. Also, presumably the comp package for a new CEO would include a substantial package of at-current-market options, which are more attractive if the current price is low.
If I could afford to buy all of them, I would not need to buy any of them and I sure wouldn't be spending time on the message boards!
