Philly Tide: “Someone shoot holes in this screen before I start doing it.”

You certainly have reason to be skeptical , of the many thousands of screens proposed on many sites
over the last 20 years very few have performed for even a short period post discovery and fewer that
continued to perform over a several year period.

Yeild Earn Year has been one of the most tried and true screens originally a Value Line Screen modified
to a Stock Investor Pro version when VL became unavailable. It was perhaps the best overall performer
until most abandoned it when it performed poorly from 2014 thru 2018 but did very well in 2022 &23.

ROE_Cash is a much newer screen proposed by mungofitch as a SPY alternative on 5/24/2020 with a hold 40 till drop 45. I can verify personally that it has continued to work for me from 7/2020 with some minor modifications and a hold 10.

I don’t think you can shoot down the logic of either screen but I also wouldn’t put a large portion of my
Investments in either screen. That said I have consistently beat the market by a few percent over 25 plus
Years with less volatility using multiple screens.

Aussi: “I think the backtester is doing as you say, which is merging the
results together, by reducing money from the screen that has gone up
and adds to the screen that has gone down.”

Very good point, I hadn’t thought about the blender taking money from
the screen that was doing well. That’s not the way I’ve been allocating
funds, in fact I usually move more into the screens that are working (A WWL approach)
