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.

rayvtI have virtually ZERO confidence that their tools will increase one's return better than screens that Jim has mentioned here and on TMF (r.i.p.)’

Although GTR1 is an excellent backtester it does have a significant learning curve. The majority of historical screens on both sites have had poor post discovery records but is my opinion that P123 as a result of more financial professional users and a larger staff has significantly improved from their earlier ranking systems and designer models.

But as I previously said I don't believe the typical investor will end up making a profit using P123 but for those few that are willing to commit to a significant long term learning experience can.

As for performance take a look at some of the 2024 eoy posts by P123 users.
