High β – A company with a β that’s greater than 1 is more volatile than the market. For example, a high-risk technology company with a β of 1.75 would have returned 175% of what the market returned in a given period (typically measured weekly).

Let’s go to the xts world and use the built-in CAPM.beta() function from PerformanceAnalytics.That function takes two arguments: the returns for the portfolio (or any asset) whose beta we wish to calculate, and the market returns.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.

Beta (β), which is mostly employed in the capital asset pricing model (CAPM), is a measurement of a security or portfolio’s volatility—or systematic risk—in comparison to the market as a whole.
