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.

{gWERindex24} and WERindex roughly agreed from 1992 to 2019, but WERindex shows lower returns since 2020. (WERindex data is from http://tradesim.info/chartdata.php )

  Date     WERindex  gWERindex24  ratio

year   WERindex  gWERindex24  difference

2021 26% 31% -5%
2022 -31% -26% -5%
2023 17% 27% -10%


20231031 to 20231229 return: {gWERindex24} 22%, WERindex 15%

The screen I used was:

Define {WER}
step0: [Security Type; lag=1 days] == 0,10,11,12,18,30,31,48,71,72
step1: [Mkt Days Since Security Opened; lag=1 days] >= 63
step2: [% Rank (tie-averaged) by [Average dollar-volume over 63 days; lag=1 days] (Asc) at step2] >= 50
step3: [WER Rank In List; lag=1 days] != null; Cash When None
Holding period = 21 mkt days
Frictional loss of 0.4% applied to all sales (closing long/opening short)
Equally weight new positions, fully rebalancing all liquid positions to equal weight every 1 holding periods
All trades at market close.
