Multiple Choice

Exhibit 7A.1
USE THE INFORMATION BELOW FOR THE FOLLOWING PROBLEM(S)
The general equation for the weight of the first security to achieve the minimum variance (in a two stock portfolio) is given by:
W₁ = [E( $\sigma$ ₂) ² - r_1.2 E( $\sigma$ ₁) E( $\sigma$ ₂) ] -[E( $\sigma$ ₁) ² + E( $\sigma$ ₂) ² - 2 r_1.2E( $\sigma$ ₁) E( $\sigma$ ₂) ]
-Refer to Exhibit 7A.1. Show the minimum portfolio variance for a two stock portfolio when r_1.2 = 1.

• A)E(\(\sigma\)₂) -[E(\(\sigma\)₁) -E(\(\sigma\)₂)]
• B)E(\(\sigma\)₂) -[E(\(\sigma\)₁) + E(\(\sigma\)₂)]
• C)E(\(\sigma\)₁) - [E(\(\sigma\)₁) -E(\(\sigma\)₂)]
• D)E(\(\sigma\)₁) /[E(\(\sigma\)₁) + E(\(\sigma\)₂)]
• E)None of the above
