...common sense also has a place in biotech investing.
Gee thanks! I've repeatedly stated my lack of knowledge of biotech, though I'm reading voraciously.
Had I known that TEVA was a heavyweight, I would have displayed more of the common sense that you intimate I am lacking - AND immediately grasped the significance of TEVA possibly not doing things "in-house".
Nevertheless, thank you for your explanation. It's another piece of the puzzle.
