Understanding Systematic Risk

Systematic risk is the risk that affects us all, from geopolitical issues to our day-to-day lives. It is ever-present and can be caused by a combination of factors.


β = Cov(Rx, Rm) / Var(Rm)

How do I calculate the systematic risk?

In order to calculate Systematic risk, one can use the beta coefficient. This is calculated by regressing a security's return on market return. The beta coefficient is then used as a proxy for systematic risk. To calculate this in Sourcetable, use the formula: β = Cov(Rx, Rm) / Var(Rm), where Rx is the security's return and Rm is the market return.
