I tried meeting with a "wealth management" bank once, asking them if they would implement my strategy for me. They said no.

That generally leaves trying it yourself.

The problem would be in easily getting a good source of cash & debt data. VL seems to often put out crappy or obsolete data.

Last time I successfully ran this screen was mid 2023. There were 248 stocks that passed the early filters and that I needed to get the cash & debt figures for.
I got the data by scraping the WSJ page. But now they (and many other web sites) have blocked scraping.

So...probably too much trouble, and not enough of a payoff. Might as well take the top 40 of the S&P 500 or GSPY. Equal weight or same relative weights.

=======================================

Of note is a strategy outlined in 2000 if I recall, which has been followed by one board member with real money all this time. He has done very well. The account is up 20-fold in 20 years, which is a little over 16%/year compounded. It is a spectacularly wild ride, though.

That was Elan. Very wild ride!! I did quite well on that strategy for a while, but when it stops working it STOPS WORKING. After about 5 consecutive months where the strategy lost 100% of its money I threw in the towel.
