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.

There is good agreement between GTR1 and P123 for these screens, with the CAGRs close, and CorMER near 1.

  Screen   GTR1   P123   diff   CorMER
SP500ew 12.0% 12.0% 0.0% 0.64
SP1500ew 11.3% 11.4% 0.2% 0.99
RS2000ew 9.0% 9.5% 0.5% 1.00
NasBig100 13.9% 12.3% -1.6% 0.94


(RSP is used as the benchmark when calculating CorMER, and this lowers CorMER for SP500ew.)
