FINAL ASSIGNMENT RE SUMBITTING : DUE BY 26TH AUGUST 2016 Your Task QUESTION 1 The managing partner for Westwood One Investment Managers Inc. gave a public seminar in which she discussed a number of issues, including investment risk analysis. In that seminar, she reminded people that the coeFcient of varia±on can o²en be used as a measure of risk of an investment. To demonstrate her point of view, she used two hypothe±cal stocks as examples. She let x equal the change in assets for a $1,000.00 investment in stock1 and y re³ect the change in assets for a $1,000.00 investment in stock2. She showed the seminar par±cipants the following probability distribu±ons: x P(x) y -1000 10% -1000 0 10% 0 500 30% 500 1000 30% 1000 2000 20% 2000 sample mean 500 sample mean 500 (2 marks) expected value of x = 750 expected value of y = 100 (3 marks) frst compute variance x = 0.10(-1000-750)^2 0.10(0-750)^2 0.30(500-750)^2 0.30(1000-750)^2 0.20(2000-750)^2 y = 0.20(-1000-100)^2 0.40(0-100)^2 0.30(500-100)^2 0.05(1000-100)^2 0.05(2000-100)^2 sample std dev = sx = 844.10 sample std dev = sy = 717.64 (2 marks) a. Compute the expected values for the random variables x and y. b . Compute the standard devia±ons for the random variables x and y. c. Compute the coeFcient of varia±on for each random variable.
