k and All:
All the responses are reasonable. Six years is too short to test on. If you can actually trade your model, you should do great.

Thanks for clarifying, Kumar. It makes sense now. Out of curiocity, are you using a broker with discount trading rates, such as IB where they charge a per-share trading cost? I’m presently trading in my self-directed 401k where trades are $9.99 each for 1 share or 1,000,000. So even through I’ve been able to simulate that this type weekly rebalancing is more profitable, I can’t take advantage of it with the $'s I have available in any particular port. But time is on my side. 
Chris/strader1,
Thank you for the well wishes.
I am using IB for my p123 20 stocks portfolio with weekly rebalance.
I have 401k with Fidility (not self managed).
Would like to know how long you are following quant system and have investment experience.
Thanks
Kumar
