Cytek Biosciences (NAS:CTKB) 3-Year Sortino Ratio Explanation
The 3-Year Sortino Ratio inidicates the risk-adjusted return of an investment over the past three year. It is calculated as the annualized result of the average three-year monthly excess returns divided by the standard deviation of negative returns in the three-year period. The monthly excess return is the monthly investment return minus the monthly risk-free rate (typically the 10-year Treasury Constant Maturity Rate). If the risk-free rate for a specific region is not available, U.S. data is used by default.
Differnt from the Sharpe Ratio that penalizes both upside and downside volatility equally, the Sortino Ratio penalizes only those returns falling below a user-specified target or required rate of return. The expected returns here is set to the risk-free rate as well.
