Risk Models : PyPortfolioOpt includes multiple ways to compute the covariance matrix of asset returns, an essential input for many portfolio optimization algorithms. This is implemented as the max_sharpe() method in the EfficientFrontier class. It also can be used to calculating portfolio returns like XIRR. skfolio is a Python library for portfolio optimization built on top of scikit-learn. ) and provides a vast array of utilities, from performance measurement and evaluation to graphing and common data transformations. The Sharpe-ratio is the average return earned in excess of the risk-free rate per unit of volatility or total risk. It is calculated as the average return over the risk-free rate divided by the standard deviation of the excess return. For example, to get to 'per root month', multiply by $\sqrt{253/12}$.
