Calculate Dollar-Weighted and Time-Weighted Returns for the following:
At the beginning of Year 1, an investor buys one share of Good Chips stock for $12. At the end of Year 1, the investor receives a dividend of $1 and buys another share of Good Chip stock for $16. At the end of Year 2, the investor sells both shares for $20 each.
Dollar-Weighted: 30.5%
CF0: –$12
CF1: $1 – $16 = –$15
CF2: $20 + $20 = $40
Time-Weighted: 33.3%
CF0: -$12
CF1: $1
CF2: $20

Seth bought ABC stock for $21 per share 6 months ago. Seth sold ABC today for $29.40 per share. What is his annualized return?
Annualized return = ($29.4/$21)2 − 1 = (1.4)2 − 1 = 1.96 −1 = 0.96, or 96%
A CD offers 3% per quarter. What is its annualized return?
EXACT Answer - DO THE MATH ON YOUR CALCULATOR
Annualized return = (1.03)4 − 1 = 1.1255 −1 = 0.1255, or 12.55%

Calculate the expected return of the following portfolio:
Answer: 33.5%
According to the Capital Asset Pricing Model (CAPM), if the risk-free rate is 3% and the market portfolios expected return is 10%, what is the expected return of a stock with a beta of 0.7?
Answer: 7.9%
Expected return = rf + β (rm – rf)
Expected return = 3% + 0.7 (10% − 3%) = 3% + 0.7 (7%) = 3% + 4.9% = 7.9%
Glen is considering two portfolios: 1) Portfolio A with a return of 14 percent and a standard deviation of 14 percent and 2) Portfolio B with a return of 4 percent and a standard deviation of 7 percent. Assuming the correlation between A and B is 0.0 and Glen invests 70 percent in A and 30 percent in B, what range of returns should this portfolio produce 95 percent of the time?
A) Between 1% and 21%
B) Between -9% and 31%
C) Between -1% and 21%
D) Between -19% and 41%
The correct answer is (B).
Standard deviation:
=SQRT[(0.7² x 14² ) + (0.3² x 7² ) + 0]
=SQRT[(0.49 x 196) + (.09 x 49)]
=SQRT[96.04 + 4.41]
=SQRT[100.45]
=10.02% or about 10%
Expected return = (0.7 × 14%) + (0.3 × 4%) = 11%
As noted in Chapter 2, the 95 percent confidence interval equals two standard deviations from the mean. Therefore the range -9 percent to 31 percent is the correct answer.
Discount, Inc., expects to generate $100 million in operating cash flows during the next year. It estimates its long-term dividend growth rate to be 2%, and it has 50 million shares outstanding. What is the intrinsic value of Discount, Inc., if your required rate of return is 10%?
Answer: $25
Intrinsic value = Total market value / Outstanding Shares.
Total market value = Operating Cash Flow / (Required Rate of Return – Dividend Growth Rate)
Total market value = $100,000,000 / (0.10 − 0.02) = $100,000,000 / 0.08 = $1,250,000,000
Intrinsic value = $1,250,000,000 / 50,000,000 = $25
The Nacho Equity Fund has a beta of 1.44 and a standard deviation of 20.8%. It has returned 12.9% during the past year when the return on one-year Treasury bills has been 3.2%. The Sharpe Ratio of the Nacho Equity Fund is closest to:
Answer: 0.466
Sharpe = (Portfolio Return – Risk-Free Rate) / (Standard Deviation)
Sharpe = (12.9 – 3.2) / 20.8 = 0.466
The Southern Fund generated a return of 7% over the last year. The relevant market portfolio had a return of 10% and the risk-free return was 3%. Southern Fund’s beta is 0.6. The Jensen’s alpha for the fund is closest to:
Answer: -0.2
α = rp – [rf + βp × (rm – rf)]
α = 7 – [3 + 0.6 × (10 – 3)] = − 0.2
Last year, the risk-free rate was 2% and a tech sector index returned –10%. What is Jensen’s alpha for a tech mutual fund with a beta of 1.2 that returned –11% over the same period?
Answer: 1.4
α = rp – [rf + βp × (rm – rf)]
α = -11 – [2 + 1.2 × (-10 – 2)]
α = -11 - [2 + (1.2 x –12)]
α = -11 - [2 - 14.4] = -11 + 12.4 = 1.4
What is the Treynor ratio of a fund with a beta of 1.3 and a standard deviation of 15% if the fund returned -8% this year when the risk-free rate of return was 2%?
Answer: -7.69
Treynor ratio = (rp – rf) / β
Treynor ratio = (-8 – 2) / 1.3 = -7.7
James buys a 6% coupon bond with a $1,000 par value on September 30th. The bond pays semiannual interest on Jan 1st and July 1st each year. What is the amount of accrued interest that James must pay to the seller of the bond?
Answer = $15
Semiannual coupon PMT x (Days since last coupon payment / Days in coupon period)
= ($1,000 x 6% / 2) x (90 / 180)
= $30 x 1 / 2
= $15
All of the following regarding Treasury Inflation-Protected Securities (TIPS) are true EXCEPT:
A. TIPS are issued directly from the U.S. Treasury.
B. The interest rate for TIPS changes based on inflation.
C. TIPS can be purchased on a competitive or noncompetitive basis.
D. With deflation, the interest payments will decrease for TIPS.
B
TIPS are issued by the U.S. Treasury on both a competitive and noncompetitive basis. The interest rate does not change. Instead, the principal amount changes based on inflation or deflation.
The Echo bond is a 6% coupon bond with semiannual coupon payments. It matures in 15 years with a $1,000 par value. If the YTM for this bond is 4%, what is the value of the bond?
Answer: $1,223.96
P/YR - 2
FV - 1000
N - 15x2 = 30
I - 4%
PMT - 30
PV = 1223.96
Arthur is considering purchasing a 12-year bond that is selling for $1,300. What is the current yield for this bond if it has an 8% coupon, paid semiannually.
What is the current yield?
Answer: 6.15%
Current yield = ($1000*.08)/$1,300 = 6.15%
1000 = par value
.08 = interest rate
1300 = PV
Carla is considering purchasing a 35-year bond that is selling for $500 and has a $1,000 par value. What is the YTM for this bond if it has a 2% coupon, paid semiannually?
Answer: 5.06%
P/YR = 2
PV = -500
N = 70 (35X2)
PMT = 10 (2% OF 1000 / 2)
FV = 1000
I = 5.06%
A company with 500 million shares outstanding paid a dividend of $2 this year. If the company’s net earnings were $4 billion, what was its dividend payout ratio?
Answer: 25%
The payout ratio = dividend per share / EPS
The payout ratio = $2/($4,000,000,000/500,000,000) = 0.25 = 25%
Monica purchases one share of stock on margin for $104. The initial margin is 50%. If the maintenance margin equals 35%, then Monica will receive a margin call if the stock falls below what number?.
Answer = $80
Andre purchased shares of Latte Co. for $48 by using a margin account with a 50% initial margin rate and a 30% maintenance margin rate. At what price will Andre receive a margin call?
Answer = 34.29
The formula to determine the price at which a margin call will occur is as follows:
Debt / (1 − Maintenance Margin Rate). $24 / (1 − .30) = $34.29
