Sorry, make that SGEN versus CLDX. Eric Dobmeier is Chief Operating Officer of Seattle Genetics, and added to the STML board. SGEN and CLDX are partners and I own both, along with a number of other bio's, so was mixing data. :-)
PS, market cap is only $300 million, that's gonna look very reasonable over time, and presents an excellent entry point to begin building core, and trading positions. These are always long term plays, but the pedigree and price are compelling to start working with.
