Michael Carr and Karen Bocock are analysts for the Portfolio Optimization Group. Carr and Bocock are discussing the firm’s mean variance optimization model for equity holdings and the pros and cons of using market model estimates or historical estimates as inputs to the model. Carr states, “One of the main concerns I have about the model is that whether we are using market model estimates or historical estimates, we are implicitly assuming that the historical relationship between the stock and the market is indicative of the future.” Bocock replies, “One of the main advantages to using the market model estimates is the fact that there are fewer parameters to estimate.” With regard to their statements about methods for computing the inputs for a mean-optimization model: A) Carr is incorrect; Bocock is incorrect. B) Carr is correct; Bocock is incorrect. C) Carr is correct; Bocock is correct. D) Carr is incorrect; Bocock is correct. Given a three-factor arbitrage pricing theory (APT) model, what is the expected return on the Premium Dividend Yield Fund? The factor risk premiums to factors 1, 2 and 3 are 8%, 12% and 5%, respectively. The fund has sensitivities to the factors 1, 2, and 3 of 2.0, 1.0 and 1.0, respectively. The risk-free rate is 3.0%. A) 33.0%. B) 28.0%. C) 36.0%. D) 50.0%.

C. C.

- C 2. C

i’ll take A, C

C, C T/G

B, C

Carr is correct. Bocock is correct too - we need 3n + 2 only So C and C?

B – Not sure about this one C

I would agree with C and C

for the first one- carr is correct - you hope that history repeats itself bocock - market model: e®=alpha + beta * Rm etc… --> C second : 0.08 * 2 + 0.12 + 0.05 + 0.03 = 0.36 C too C,C

answers are C and C

C, C.

i also got C and C

C and C… that’s a big expected return.

B) Carr is correct; Bocock is incorrect. C) Carr is correct; Bocock is correct. D) Carr is incorrect; Bocock is correct. Your answer: A was incorrect. The correct answer was C) Carr is correct; Bocock is correct. Carr’s statement is correct. Using historical estimates and market model estimates both involve the implicit assumption that the historical relationship between a stock and the market is indicative of the future relationship. The historical estimate method uses direct historical means, variances, and correlations as inputs to the model. The market model method regresses historical returns against returns for the market and assumes that returns for each asset are correlated with returns to the market. Since both methods use some form of historical data, both assume that history is indicative of the future. Bocock is also correct. The historical estimate method requires a large number of estimates, especially for computing the covariances between every stock in a portfolio. The market model estimate method simplifies the process significantly (resulting in fewer parameters) since all stock returns are assumed to be correlated with the market. Given a three-factor arbitrage pricing theory (APT) model, what is the expected return on the Premium Dividend Yield Fund? The factor risk premiums to factors 1, 2 and 3 are 8%, 12% and 5%, respectively. The fund has sensitivities to the factors 1, 2, and 3 of 2.0, 1.0 and 1.0, respectively. The risk-free rate is 3.0%. A) 33.0%. B) 28.0%. C) 36.0%. D) 50.0%. Your answer: C was correct! The expected return on the Premium Dividend Yield Fund is 3% + (8.0%)(2.0) + (12.0%)(1.0) + (5.0%)(1.0) = 36.0%.

OMFG, I totally missed the Rf rate = 3% on the last line…I was thinking this was complicated. I could only pray for a question like #2 on there, hahaha. Thanks boston!
