Answer:

A, B.

Explanation:

E(r) = Rf + beta (Risk premium on factor)

PORTFOLIO A

19% = 11% + 1.7(RP)

19% - 11% = 1.7(RP)

(RP) = 0.08/1.7

(RP) = 0.047059

(RP) = 4.706%

PORTFOLIO B

15% = 11% + 0.6(RP)

15% - 11% = 0.6(RP)

(RP) = 0.04/0.6

(RP) = 0.06667

(RP) = 6.667%

As risk premium is lower in case of portfolio A, the correct strategy is Short Position in Portfolio A and Long Position in Portfolio B
