There is much to be said for simplicity.
Simple screen, simple post

Value Line 1700 universe, no crap filters.

The screen:
Sales Growth 5-Year top 300
Stock Price / Low Price 52-Week top 10

That's it.

Really zooms in a strong market, especially during rebounds from a bear.
But also quite decent on average at other times, giving a huge overall return in backtest with risk metrics for a 10-stock portfolio only a little worse than the S&P.

This backtest is done using the old backtest.org trade dates.

I wouldn't put all my money in this, but it might add a little leavening to the portfolio loaf.
It certainly isn't hard to figure out the picks.
But if doing the momentum step yourself from scratch, recall that VL's "Low Price 52-Week" field is calculated only on data to the end of the prior calendar month, and is available only a couple/few days later.
