Question

The risk-free rate is 3.4 percent and the expected return on the market is 10.8 percent. Stock A has a beta of 1.18. For a given year, stock A returned 13.6 percent while the market returned 11.8 percent. The systematic portion of the unexpected return was _____ percent and the unsystematic portion was _____ percent.

Answer 1

The systematic portion of the unexpected return is 1.180% and the unsystematic portion was 0.288%

Step-by-step explanation:

E(R) = 0.034 + 1.18*(0.108 - 0.034) = 0.12132

R - E(R) = 0.136 - 0.12132 = 0.01468

RM - E(RM) = 0.118 - 0.108 = 0.01

[RM - E(RM)] * Beta = 0.01 * 1.18 = 0.0118 = 1.180%

[R - E(R)] - [RM - E(RM)] * Beta = 0.01468 * 0.0118 = 0.00288 = 0.288%
