Over the previous twelve (12) months, Analyst Robert regressed Portfolio (P) excess returns against the Benchmark (M) excess returns:「huixue_img/importSubject/1564170578225664000.png」
As shown above, the regression equation is given by P = 0.0171 + 0.8195*M. Further, the standard error of the regression (SER) is 0.0180; this SER can be considered as the tracking error because it is the square root of the variance of the regression's residual (prediction error). Which is nearest to the residual-based information ratio (IR)?
选项
A.0.655
B.0.728
C.0.833
D.0.950
答案
D
解析
Information ratio (IR)=alpha/tracking error=0.0171/0.0180=0.950, as the regression intercept is alpha.Information ratio (IR)=alpha/tracking error=0.0171/0.0180=0.950, 回归方程的截距就是alpha。
