What could cause a stock to trade below book value?
all of these examples are great if you actually believe in fundamentals, but who believes in fundamentals alone any more? Stock prices are driven by earnings, news, and public perception. For instance, a pharma company named Eyetech has their new macular degeneration drug approved by the FDA, and yet their stock price plummeted. Typically when a small pharma company gets a drug approved, it's off to the races. But, Genetech came out said their macular degeneration drug was going to be far more effective, and that they were well on track for approval.
