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.

This is why you shouldn't give up on using AI to find safest high-cagr portfolios using the strategies I have posted here

Does the AI know the meaning of "data dredging"?

Does the AI know the meaning of the difference in returns between the 1985-2006 and the 2006-2026 periods of these momentum strategies? Does it have any conclusions as to which -- if any -- period it should take as the most meaningful?

In one screen, one period had 32% CAGR and the other had 21%, and 1985-2026 had 27%.



Luckily for me, I don't have a dog in that fight. No AI can replace me, because there is no such thing as being fired from retirement. :-)

Fiddling with GPT1 and a spreadsheet all morning beats walking around the block 10 times.
