1 | P a g e CHAPTER : 8 Q.7: Consider the following two regression lines for stocks A and B in the following figure: a) Which stock has higher firm-specific risk? The stock security characteristic lines (SCL) are shown in the two illustrations. Because Stock A's observations deviate more from the SCL than Stock B's do, Stock A has a higher firm-specific risk. Each observation's vertical distance from the SCL is used to calculate deviations. b) Which stock has greater systematic (market) risk? The systematic risk metric, or beta, is the slope of the SCL. Because Stock B's SCL is steeper, there is a higher systematic risk associated with Stock B. c) Which stock has higher R²? The ratio of the explained variance of the stock's return to the overall variance, which is the sum of the explained variance and the unexplained variance (the stock's residual variance), is known as the SCL's R2, or squared correlation coefficient: ) ( σ σ β σ β 2 2 2 2 2 2 i M i M i e R + = Given that Stock B's beta is higher and its explained variance (which is 2 2 σ β M B ) is higher than Stock A's, along with a smaller residual variance ( 2 ( ) B e ), Stock B's R2 is higher than Stock A's. d) Which stock has higher alpha? The SCL's intercept with the predicted return axis is known as alpha. Because Stock B has a negative alpha and Stock A has a modest positive alpha, Stock A has a bigger alpha. e) Which stock has the highest correlation with the market? Since the correlation coefficient may be calculated using the square root of R2, Stock B has a stronger correlation with the market.
2 | P a g e Q.8: Consider the two (excess return) index model regression results: For A: For B: RA=1%+1.2RM R-square=0.576 RB=-2%+0.8RM R-square=0.436 Residual standard deviation=10.3% Residual standard deviation =9.1% a) Which stock has more firm-specific risk? The residual standard deviation is used to calculate firm-specific risk. Stock A therefore has a higher firm-specific risk: 10.3% is higher than 9.1%. b) Which has greater market risk? Beta, the regression's slope coefficient, is used to quantify market risk. A's beta coefficient is higher: 1.2 is greater than 0.8. c) For which stock does market movement explain a greater fraction of return variability? R2 calculates the percentage of the return's entire variance that can be attributed to the market return. The R2 of A exceeds that of B: 0.436 < 0.576 d) If rf were constant at 6% and the regression had been run using total rather than excess returns, what would have been the regression intercept for stock A? Replacing excess return (R) with total return (r) in the SCL equation: ( ) (1 ) A f M f A f M r r r r r r r = + = + + At this point, the intercept equals: (1 ) 1% (1 1.2) f f r r + = + The intercept would be as follows since rf = 6%: 1% 6%(1 1.2) 1% 1.2% 0.2% + = = −
