Methodological Uncertainty in Portfolio Sorts

This repository contains code for "Methodological Uncertainty in Portfolio Sorts" (joint work with Dominik Walter and Rüdiger Weber). The manuscript was previously circulated as "Non-Standard Errors in Portfolio Sorts".

We share the full replication code and an all-in-one solution. The later covers all steps from data download to the actual portfolio sorts that embrace NSE by constructing 69,120 return differentials as estimates for the variable asset growth. There is a blog post on the Tidy Finance Blog covering this very solution.

The code is open source and available here. Please cite the corresponding paper:

Code: Tidy Finance with R

The project's code is inspired by Tidy Finance with R (joint work with Christoph Scheuch and Stefan Voigt).
