I can't see how paperboy could afford to buy more. they buy with each placement and buy on the open market too. paperboy (and joe cook) were smart enough to see value in AMLN back when it was at like .30 cents and they bailed it out. They are doing the same thing with CORT.
What do you make of the latest line of credit equity financing? $60M over 36 months with max shares issuable of 9.6M nets out at $6.25/sh. I think this is why insiders have been buying.
