Calculate beta of a portfolio.

However, if you have no portfolio to start with, unsystematic risk is more relevant to you. In this case, standard deviation is your friend because it accounts for both risk types. Beta is volatility in relation to a benchmark whereas Standard Deviation is volatility in relation to actual returns vs expected returns.11. I would use the identity and three step process that: Total Variance = Systematic Variance +Unsystematic Variance. You can calculate systematic variance via: Systematic Risk = β ⋅σmarket ⇒ Systematic Variance = (Systematic Risk)2. then you can rearrange the identity above to get: Unsystematic Variance = Total Variance −Systematic ...There are two ways the SIM can be expressed, either in " raw returns " (aka ordinary returns) or in " excess returns ."
