Subject: Re: new dervied Nasdaq100 weekly strategy
Thanks for posting another interesting screen with suggestions (weekly trading, short-term momentum reversal). The OP screen looks for stocks:

Large Cap Growth (Nasdaq 100)
high 1-year momentum
low 1-week momentum (short-term momentum reversal)
weekly trading

The short-term momentum reversal steps (steps 2 and 3) reduce CAGR, Beta, drawdown, and depth, while more than doubling the number of trades (AT). (Depth is the average count of stocks passing the final step.)

Results from 19850201 to 20251128 (longest backtest):

I prefer the version with higher CAGR and less trading. Low Beta would help when blending with other screens, but this screen's CAGR is so high that I prefer to just evaluate it on its own.
