"Now just what does SGEN have that PTSC doesn't?

A NASDAQ listing."

And your point on this issue is......? Are Nasdaq listings something that you have to ask Santa for and hope that he brings to you on Christmas?

What SGEN also has that PTSC doesn't, is a pretty strong BOD with skills and connections that enhance and complement their business model and focus, and a much more transparent and forthright communication strategy.

As for ONXX, if you look at their revenue for FY07, you'll see that it was non-existent and their share price was in the $12 range. Since then, they've recorded revenues that seem to be fluctuating up and down between $40M and $85M per quarter and their share price is at $30 currently. On the other hand, PTSC went from zero revenue to tens of millions in revenue and shot up, and while they're still pulling in decent revenue, relative to where they were, their share price has dropped over 90% and is back to what it was before they had positive earnings.

OK, heck, I'll compromise with you and take the ONXX model you recommend then, since you seem to object to the SGEN model.
