Metrics Reference
An exhaustive list of metrics that are available on the site with the formulas used and interpretation if any.
Metrics
CAGR
Compounded annual growth rate of a value series. Also known as the geometric mean.
[(1 + R1)(1 + R2)(1 + R3)...(1 + Rn)]^(1/N_years) - 1.0
Active Return
Difference between a portfolio return series and a benchmark return series. Also known as Excess Return
[(1 + A1)(1 + A2)...(1 + An)] - 1.0
Where:
- A(t) = Portfolio Return(t) - Benchmark Return(t)
Avg Active Return
Average Difference of Active Return
(A1 + A2 + A3 + ... + An) / n
Tracking Error
Standard Deviation of Active Return
STDDEV([A1, A2, A3 ..., An])
Sharpe Ratio
Risk adjusted measure of return. Determine how much rewards per unit of risk. Annualized by default
Monthly SR = Mean(Excess Returns) / Std Dev(Excess Returns)
Annual SR = Monthly SR * √12
Note:
Excess Monthly Return(t) = Portfolio Month Return(t) - Monthly Risk Free Rate(t)
Sortino Ratio
Risk-adjusted returns by focusing only on downside volatility. Annualized by default.
Monthly Sortino Ratio = Mean(Excess Returns) / Downside Deviation
Annual Sortino = Monthly Sortino * √12
General Note
R(t) is return in that period
(value(t) - value(t-1)) / value(t-1) - 1.0
FED 3-Month Treasury is used as risk free rate by default.
