Smallcap momentum portfolio

This is really incredible. I am also contemplating this strategy to adopt in a few weeks time. However, I am thinking to do these tweaks:

1. Top NSE 750 stocks as universe.
2. Monthly rebalancing or at least in 15 days
3. I will do the asset allocation like 80% in equity and 20% in totally uncorrelated asset such as Gold.

Also, my criteria will be slightly different:

1. I will rank the stocks based on weighted average return in last 12, 6 and 3 months and also on their Sharpe ratios.

2. I will also select technically strong stocks such as stock above 200 SMA and 100 SMA and near to their 52 weeks high.

Though I am a fundamental investor by heart and will continue to be but I want to diversify my strategy to make extra alpha on my returns.

What do you think about this? Please suggest.
