The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" 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.

The "d" indicates derived field, that is, GTR1 calculates it based on fundamental data, rather than using the SiPro supplied field.
As I recall Robbie did this since there were often SiPro calculation errors that could be avoided by calculating from base data.

Having said that, I think there is something going on with GTR1, was just putting together a post on it.
Between yesterday and today, all of my screens changed more or less 100% with completely new tickers.
Yet, GTR1 has the same data date (11/29) for both runs. Normally I would suspect that new fundamental data became available.
However my intuition is that something else is going on.
