4) Which of the
equations is incorrect?
A) Var(R)
C) Var(R) =
∑RPR×(R E[R])2
D) E[R] = ∑
RPR×R
Answer: A
Explanation: A) SD(R) = B) C) D)
Diff: 2
Topic: 10.2 Common Measures of Risk and Return Skill: Conceptual
B) SD(R)
Use the table for the question(s) below.
Consider the following probability distribution of returns for Alpha Corporation:
Current Stock Stock Price in Probability Price ($) One Year ($) Return R PR
$35 40% 25%
$25 $25 0% 50%
$20 -20% 25%
5) The standard deviation of the return on Alpha Corporation is closest to:
A) 22.4% B) 19.0% C) 21.8% D) 19.4% Answer: C
Explanation:
A)
B)
C)
E[R] = RPR×R = .25(40%) + .50(0%) + .25(-20%) = 5%
4.75%
SD(R) = = .2179 or 21.79% D)
Diff: 3
Topic: 10.2 Common Measures of Risk and Return Skill: Analytical
∑
Var(R) = ∑RPR×(R E[R])2 = .25(.40 - .05)2 + .50(.00 - .05)2 + .25(-20 - .05)2 = .0475 or

6) Which of the following statements is false?
A) The standard error provides an indication of how far the sample average might deviate from the expected return.
B) The 95% confidence interval for the expected return is defined as the Historical Average Return plus or minus three standard errors.
C) We can use a security s historical average return to estimate its actual expected return. D) The standard error is the standard deviation of the …… 此处隐藏:10659字,全部文档内容请下载后查看。喜欢就下载吧 ……
