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.

gprc also includes adjustments for splits, aprc does not.


gprc, per se, is not an investable parameter. It is unique to GTR1.
aprc is based on gtoa.a and grpc. "gtoa.a's main purpose is detecting and correcting for stock splits"
Which seems to imply that aprc DOES account for splits.
(FWIW, I get dizzy trying to follow the field definitions in the GTR1 documentation.)

Regardless, ignoring splits would give a stock a *lower* computed momentum and would thus incorrectly exclude a strong stock rather than incorrectly include a weak stock.

It doesn't matter anyway. The results are virtually identical.

Here is using gprc:
