Calculate beta of a portfolio.

9.1.2. Ex-Ante Beta. From a computational perspective, a simple way to compute an ex-ante beta is to compute the risk of every asset in the portfolio to X. Once you have the covariance between X and every asset in the portfolio, you can then define the ex-ante beta to X as: β = ∑nk=1 wk * Cov (X,sk) * h.

If the market or index rate of return is 8% and the risk-free rate is again 2%, the difference would be 6%. 5. Divide the first difference above by the second difference above. This fraction is the beta figure, typically expressed as a decimal value.Covariance and variance are directly calculated in pandas which makes it fast.
