famafrench

famafrench is a Python library package designed to replicate and construct datasets from
Ken French's online data library via remote access to the wrds-cloud by querying CRSP, Compustat Fundamentals Annual, and other datafiles.

This module uses the WRDS-Py library package to extract data from CRPS, Compustat Fundamentals Annual, and other datafiles via the cloud for use with the Pandas-Py package.

famafrench's current efficient performance results from features such as the use of a least recently used (LRU) cache implemented using the Python decorator functools.lru_cache.

Contributing

I welcome recommendations, contributions and/or future collaborations. I am ambitious and plan to expand the module to include construction of additional factor-based datasets relevant for empirical asset pricing. These include the following:

• AQR Capital Management:

  • Betting Against Beta (BAB)
  • Quality Minus Junk (QMJ)
  • Modified Value - High Minus Low (HMLD)

• Lettau, Ludvigson, and Ma (2019) Capital Share Factor:

  • Capital Share of Aggregate Income (KS)

• Pastor and Stambaugh (2003) Liquidity Factors:

  • Non-Traded Liquidity Factor
  • Traded Liquidity Factor

• Sadka (2006) Liquidity Factors:

  • Fixed-Transitory Factor
  • Variable-Permanent Factor

• Stambaugh and Yuan (2017) Clustered Mispricing Factors:

  • Management-related Factor (MGMT)
  • Performance-related Factor (PERF)
  • Mispricing (non-clustered) Factor (UMO)

Performance and speed improvements are also appreciated.

Please report any bugs or errors to my github page or please send me an email at chris.jauregui@berkeley.edu.
