is it just because he didn't phrase his question with the word 'alpha' in it? Strategies, alpha generation in gneral, are central to quant work. How could this question possibly be off topic? –  glyphard Feb 9 '11 at 3:36

1 Answer 1

There are two broad categories of trading strategies.

  1. Momentum strategies(e.g trend following)
  2. Mean reversion strategies.

Elder's book outlines the major ones: http://www.amazon.com/Trading-Living-Psychology-Tactics-Management/dp/0471592242

And the depressing truth about most of these strategies is outlined by Aronson: http://www.amazon.com/Evidence-Based-Technical-Analysis-Scientific-Statistical/dp/0470008741/

I'm not depressed. I enjoy working in a non-deterministic space. :) –  Pete Feb 8 '11 at 18:51
