How is the riskgrade calculated?
The RiskGradeTM measure is a risk indicator that is based on the volatility of returns. The higher the volatility of returns, the higher the RiskGrade of an asset.
RiskGrades are scaled volatilities, where the scaling factor is chosen to simplify the interpretation of a RiskGrade. A RiskGrade of 100 is set to be equivalent to an annual volatility of 20%.
