There is a lot of talk these days about whether the market is in a bubble and that a crash akin to 1987 may be lurking around the corner, ready to take a huge bite out of your portfolio.

Nowhere in the market is this talk more pervasive than in the biotech sector, where multibagger returns have become commonplace, even outside the speculative penny-stock realm. In the past year alone, of a possible 165 biotech stocks with a market cap of at least $200 million, 37(!) of them have at least doubled in share price.
