The investing strategy I understand the best and feel most comfortable with is diversified shorting- taking a large number of very small positions in common shares of crappy stocks. I mainly short stock promotions and pump and dumps, where I think I have a sizable edge over other market participants. The performance of my strategy backtests to ~15% from May 2014 to August 2015.
The key to making this strategy work is being able to quickly find a large number of awful stocks. This is possible because stock fraud is an industry. Scumbags network and share knowledge with each other. Fortunately for me, this makes them really easy to find.
