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.

Here are the statistics for RS52 using the cycle which has the 25th percentile return.
For a few timing schemes. The no new 99-day high in the last 99 days is #4.
Timing is computed weekly, except daily for the 99-day, and id applied at the monthly trading day.

For 1985-2026, timing had little effect on the return. #4 was worst on risk metrics.
For 2006-2026, #4 had the slightly best return, slightly worse risk metrics except for Sortino Ratio.

For me, the only reason to use #4 was if I believed that the future was going to look more like 2006-2026 instead of 1985-2006.
