Proprietary futures trader as a career. Trading biotechs as a hobby. 4 years in and going strong. I like micro-cap companies, with upcoming catalysts. Their cash situation, vicinity to 52wk hi/lo, volume are all important factors. As well as going long stock I'm getting experience with options, especially calls that sit behind a catalyst. Trades are held from less than a week to several months. Depends on the individual company's catalysts and events. Fear and greed move stocks far beyond where fundamentals say they should be, and I try to profit from that rule.
