It is not a system, more a long term quantitative method based on a working model.
I didn't have it in 2008, started trading it from March 2010.
I have tested it from 1995 till 2005 on the US market, and from 2005 till 2010 on the Indian market, and it has beaten the index every single year, except 2002 and 2008, with yearly returns ranging from +40% to +430%.
2008 was a bad year with a return of -35%, but most mutual funds lost more than 50-80% at that time.
Returns following bear years are much bigger, 2009 returns were above 400%.
