The $AVXL story is one from which a biotech investor can learn that a PR and results can at first glance appear WGT, but are objectively not. Then adjust approach with a willingness to learn instead blaming the boogeyman. Use the experience to know irrational price spikes when they happen and sell at least some of a position to own the rest at lower risk of losses and by all means keeping doing it while keeping a balanced portfolio. It takes time and disappoint, but it is a learning process to go through that can make biotech investing fruitful and exciting especially when a drug or treatment that truly helps people succeeds.
