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.

LastGood10y is the most recent date that the screen (10 deep, 21 day hold, 0.4% friction) 10-year average total return was higher than a S&P 1500 equal weight benchmark.

If you test using Top 5 picks rather than Top 10, and if you use the standard S&P 500 as a benchmark rather than S&P 1500 Equal Weight (which itself has underperformed the S&P 500 over the past 10 years), the results are quite different.

For example, the Shrinkage screen (Top 5) only delivered a CAGR of 5% over the past 10 years, whereas the S&P 500 return in the same period was over 12%. See discussion.fool.com - Yr backtests on select si pro screens

Returns of other well-known SI Pro screens (Top 5) over the past 10 years are given at discussion.fool.com - Yr backtests on select si pro screens

According to the post linked below, there were 7 SI Pro screens that did beat the market during this most recent 10-year period:
