Implied in Dr. Tracy's last post is another point: sure small, biotech is risky, but, Cortex future has nothing to do with the Dow, Chinese exports, Lou Dobbs, Greenspan, the growing service economy, the real estate boom or anything else on a macro view of the economy.
In a sense, you are additing diversity to your investment by buying small, cap "story" stocks such as Cortex. If the story doesn't hold water, ampakines lead to two heads forming(on the neck), then the stock goes to 0. But if the promise of ampakines develops even in a few indications such as Alzheimer's, ADHD or Schizophrenia, then the stock will rise, and it will rise or fall independent on what Bin Laden does, or what the Dow does.
