I don't think anyone is arguing that Momenta isn't a good buy at $15.40.
If that's true isn't is a better buy at $14.40, $13.40 or $12.40?
My view is that there's a lot of room between todays price and Momenta true value so what's the hurry? If I lose a buck or two to the upside it shouldn't have that great of an effect. I would be more than happy to see the Macro situation clear itself up first and lose the buck or two to the upside before I jump back in.
