This one:
Do not trade the second strategy book until it is corrected. If you are in it, I would close all positions of the second strategy book.
[The first strategy book (“AI Actuals and Estimates Earnings Momentum Mid and Big Caps 5% VIXY”) has a ranking system that is equally weighted, I tested all the factors, and they are 100% fine! So, no worries.]
What happened?
The ML Model misinterpreted a factor and assigned it too much weight.
How to avoid stuff like this in the future —> we simply look at the feature importance and see if it is balanced.
This is the feature importance of the improved AI Factor Model:
Here are two (there are 6 altogether) corrected strategies of the second strategy book (this is unhedged, in the corrected book they will be hedged!).
I should have seen it, but I did not: This is my mistake. 100%!
I will take my time here, Quality first.
Best Regards
Andreas
