The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" 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.

It looks like there are 7 MI screens that have beaten the market over the past 10 years, with annual returns ranging from 13.3% to 17.5%. These are being tracked at discussion.fool.com - Curated screens...

That list may be factually true, but the conclusion that many people would draw from it could be a classic Fooled-by-Randomness trap.

If you start with a list of 100 screens, let's say, and rank them by 10 year performance, and the average screen lags the market by 5%, then you will randomly get a few screens that beat the market by a few points and a lot more screens that lag the market by more than 5%. You are virtually guaranteed that, all else being equal, a different set of screens will beat the market over the next ten years.
