The following performance data are provided for an alternative investment.

Assume the maximum drawdown risk is steady at 10.2% over each time period. Assume the average drawdown risk is steady at 6.8% over each time period. Using the data provided, calculate the Calmar ratio the way it is typically calculated. The Calmar ratio is the closest to:

选项：

A.0.46. B.0.61. C.0.65.

解释：

B is correct. The Calmar ratio is typically calculated using the prior three years of performance and is a comparison of the average annual compounded return to its maximum drawdown risk. For this particular investment, the Calmar ratio is calculated as follows: 6.2% (average compounded return over the past three years)/10.2% (maximum drawdown) = 0.60784 ≈ 0.61.
