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.

Outstanding analysis! Thank you lizgdal! Reflecting the general relative weakness of smallcaps over the last several years as the dominance of the Magnificent 7 has increased and taken over.

Brings to mind the tag line from Talladega Nights: "if you ain't first, you're last!"

* Huge drop in median excess return of screens
* Huge drop in median return of screens
* 30-40% less volatility combined with the above means less chance of an outperforming outlier screen

Yeesh.
