The Ken French Data Library is one of the most highly used publicly available data sources for financial investments and asset pricing research. Working with the data is sometimes tedious because the downloadable files come (1) compressed in zip archives and (2) having non-standard csv layouts. This package handles both of those hurdles, allowing users to get to the data faster. Usage To add the package, type ] add FamaFrenchData at the Julia REPL. Once added, type using FamaFrenchData to import the package. The package exports 4 functions: readFamaFrench , downloadFamaFrench , listFamaFrench , and clearFamaFrenchCache . For help with any of these functions, use ? at the REPL (eg. ?readFamaFrench ). Please consult the online documentation for additional detail.
