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.

Claude AI said, regarding the 2006-2026 period, "Two of three bear markets in that window (2008, 2022) were slow grinding declines, exactly the shape a long-MA filter handles best.
**His four schemes are being scored on a period that happens to suit them.**
The 2020 crash, which they'd have handled badly, was too brief to leave a mark on annual figures.

Worth checking: does the 2006-2026 advantage survive if you exclude 2008?"


So here is the check from the bottom on 3/2/2009.

Summary:
* Looking at the weekly signals, they all switch to OUT on either 1/6/2008 or 1/13/2008, so all went to cash on Feb, 2008.
* All switched to ON 7/26/09 or 8/23/09 or 6/7/09.
* All had same MaxDD.
* Sortino was slightly better for IXIC than GSPC.
* All had basically same Stdev.
* CAGR was slightly better for IXIC than GSPC.
* All CAGRs are unbelievably high.
