Biotech stocks are a close second only to internet stocks in how difficult they are to objectively value. This means that biotech stocks can be wildly under- or over-valued, which creates an opportunity for either profit or frustration for an investor that "knows better than market." To paraphrase the master: "Every now and again you should look at the stock price to see if the market is offering to do anything stupid."
This thread grew out of the "Munch-a-Biotech" thread, and is meant to discuss biotech stock valuation methods of all sorts, as well as particular stocks or sectors you may feel are under- or over-valued.
