Code and data accompanying Chen and Zimmermann's paper on open source cross-sectional asset pricing. It reproduces dozens of stock-level predictor signals in Python and portfolio constructions in R, with downloadable outputs at openassetpricing.com.

Use cases

  • reproduce cross-sectional asset pricing signals from academic papers
  • download stock characteristic data for factor research
  • understand how a predictor like BrandInvest is constructed
  • build stock portfolios from firm characteristics
  • replicate quantitative finance research results

When to choose

  • you need transparent, reproducible implementations of stock return predictors
  • you want open-source alternatives to commercial factor libraries
  • you're doing academic research on cross-sectional equity returns

When to avoid

  • you need real-time trading infrastructure or backtesting engines
  • you lack WRDS access and only need the code rather than the data
  • you want a maintained library API rather than research scripts
