Appendix: Alpha Factor Library

Separating signal from noise with Alphalens

Quantopian has open sourced the Python Alphalens library for the performance analysis of predictive stock factors. It integrates well with the Zipline backtesting library and the portfolio performance and risk analysis library pyfolio, which we will explore in the next chapter.

Alphalens facilitates the analysis of the predictive power of alpha factors concerning the:

  • Correlation of the signals with subsequent returns
  • Profitability of an equal or factor-weighted portfolio based on a (subset of) the signals
  • Turnover of factors to indicate the potential trading costs
  • Factor performance during specific events
  • Breakdowns of the preceding by sector

The analysis can be conducted using tearsheets or individual computations and plots. The tearsheets are illustrated in the online repository to save some space.

Creating forward returns and factor quantiles

To utilize Alphalens, we need...
