The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

But 147 stocks is too many to buy. How do you narrow it down to a manageable level?

ROE_RevGr5_GMI-Quality

Attemped 3 month test run as follows:(too short of course for any real "MI" data)
First Selected top 100 by Sum of Ranks
Second Buy top 25 by highest ROE
Replaced drop outs in a "My Fidelity Solo FidFolios" equal weighted account every 5 weeks

Sum of Ranks:
Quality
RevGr(5y)
RoE (TTM)

But that did have a lot of turnover.
The 25 was chosen for the test because that is the chart limit of symbols allowed(used for data export).
One year hold may be a better choice.
