Hypothesis:
Lets assume mi50 were started on 1 Jan 2008.

By the end of CY 2008, it would have been down by about 24% with max DD at 24.9%.
By end of CY 2009, mi50 would be around 1% net gain, covering all previous losses.
By end of CY 2010, mi50 would be up 50% absolute and 14.6% CAGR.

and so on….

By end of Aug 2016, mi50 would be up by absolute 623%, CAGR 25.6% and max DD still the same at 24.9%

Conclusions:

1. If you have confidence in your system, never give up.
2. If your system has failed due to changing market, at least give it a chance to perform in one full economic cycle of say 7-8 years
3. Add capital after extreme draw down years and reduce/reallocate after good years.
4. Even if we did not get the Modi wave in 2014, by end of CY 2013, having gone through one of the toughest 5 yr stock market periods in recent decades, Mi50 would have returned for 2008-2013 an absolute 129%, CAGR 14.8%, Max DD 24.9%.
