Yоu recаll the cоmment mаde by Tоm аbout extreme gains or losses. After thinking about it carefully, you realize that at ALPHA, they are not concerned about extreme gains, but only about extreme losses. Hence, you recall that semi-variance actually measures (to some extent) downside risk, or in other words, the dispersion (deviation) of returns only in cases where returns end up below the expected value (mean). Based on the following historical returns, you quickly calculate the semi-variance for UA which results in: ______________. Type your answer as decimal and not as percentage (e.g., 0.052 and not 5.2). Round to the nearest 4-decimals if needed. Do not type the % symbol. T Ri 1 [r1]% 2 [r2]% 3 [r3]% 4 [r4]%
