Hello,
Here are the 94 factors that are used in the AI paper discussed in this thread. Compustat codes are used, but should be easy to translate using our Line Items spreadsheet.
94 Factors from Green - 2016.pdf (435.3 KB)
These factors are also used in many other academic papers. The original paper by Green Et al. is here.
Many of these factors are already available in P123, others should be easily formulated. We’re reviewing them to see which one we should add as pre-defined.
Thanks
There’s a discussion of an even larger collection of academic factors on our blog, along with a public ranking system that uses the most effective ones according to a recent academic paper. You can read it here: https://blog.portfolio123.com/thoughts-on-is-there-a-replication-crisis-in-finance/
I am compiling an excel spreadsheet with all 94 factors with references. I will share the spreadsheet so that we can all contribute and input the P123 formulas for each factors.
Hello P123 community. This is the working copy for the compiled list of 94Factors. Lets all work together on the P123 formulas. Just put in your username on a factor, if you will be working to create the formula.
You need to create a custom factor called $21medmed. Instructions on how to do so are in the blog post.
I have looked at some meta-studies that have made factor discoveries that can be verified. Among other, Cross-Sectional Asset Pricing (CSAP) which has 161 different factors, Taming the factor Zoo (TFZ), has 97 different factors and Pricing via Machine Learning has 94 factors (APVML).
I’ve collected them in a sheet. There I have sorted them by return. For APVML, I build on the work of Sraby.
I am looking for a simple explanation of what is the finding of each of the studies.
I have found something on CSAP (CSAP Details) and AVPML (94- FactorLab@CityUHK), but not on AQR’s study “TFZ”.
I see that some of the studies overlap, so I can find the explanation in one of the others, but I am looking for some good overview sheets with brief explanations of the findings.
Has anyone made such an outline that they want to share?
And like Sraby, hope more people will help create a joint sheet with the codes of P123 for part of the major studies 
.
CSAP
TFZ
APVML
Did you ever get the help to gather all the 94 factors? I did not find them in the spreadsheet.
Do you know if anyone gathered all the 94 factors with the P123 code and made them public?
No update on the 94 factors.
I used Gemini 2.5 Pro and my general-purpose prompt to generate 83 factors for P123.
Some factors could not be created by Gemini based on my prompt, but it is likely that they can be approximated in P123, or that the prompt and associated data need to be improved.
Please note that I have not yet verified the accuracy of the factors. I will review them one by one and make improvements as needed.
Hi Pitmaster,
I used Gemini 2.5 Pro and my general-purpose prompt to generate 83 factors for P123.
Would you mind sharing your "general-purpose prompt?" Thank you
