1.2. Refer to the following observations for stock A and the market portfolio in the table: Month Rate of return Stock A Market portfolio 1 0,30 0,12 2 0.24 0,08 -0,04 -0,10 4 0,10 -0,02 5 0,06 0,08 0,10 0,07 a) Calculate the main statistic measures to explain the relationship between stock A and the market portfolio: i) The sample covariance between rate of return for the stock A and the market. [4] ii) The sample Beta factor of stock A. [3] iii) The sample correlation coefficient between the rates of return of the stock A and [3] the market. iv) The sample coefficient of determination associated with the stock A and the mar- ket. [4] b) Draw in the characteristic line of the stock A and give the interpretation - what does it show for the investor? [4] c) Calculate the sample residual variance associated with stock's A characteristic line and explain how the investor would interpret the number of this statistic.
