thx for a very interesting discussion. osprey, I'm sure I'm not the only one here who would be fascinated and grateful for as many substantive thoughts on healthcare/drug/biotech/device companies as you're willing to offer under blanket of anonymity. obviously the bulk of the readership here is fast-trading, primarily on the basis of technicals, charts, and patterns, but some of us are actually interested in companies and fundamentals of businesses. ruminate away whenever you can - there will be an audience.
