I think he assumes we won't notice that he gave a long-term solution to a short-term problem.
He's also somehow assumed that people invested in Greek anything are the sort looking for a low-risk, high-yield investment, when, clearly, they're up to their eyeballs in the opposite and still doing it on purpose.
He's one ouzo short of a spanakopita, if you ask me. Except the part about buying AGNC, which is a good idea for 4 more days. Then both Greece and AGNC will be changing their playing fields to suit their own desires.
