You opened a brokerage account a year ago. At that time, you bought $10,000 worth of shares of XYZ stock on margin - you used $5,000 of your own cash and borrowed $5,000 from the brokerage Örm.
(a) Right now, XYZ stock is up 6% from a year ago and you decide to get out of your XYZ holdings. Assume the brokerage Örm charges 4% interest on its margin loans, Compute your investmentís holding period return.
(b) Would you have had a higher holding period return if you had only borrowed $2,000 and used $8,000 of your own money in this investment? Explain.
(c) If the brokerage Örm charges a higher interest rate on its margin loans, would you reverse your answer to (b)? If no, how high does the interest rate need to be for you to reverse your answer to (b)? Explain.
a) Given investment amount = 10000
Own cash = 5000
Margin loan =5000
Given interest rate = 4% on margin loan
Hence interest = 4% of 5000= 200
Given return on stock = 6%
Hence return on stock = 6% of 10000= 600
Hence Net return = Return on stock - interets expense = 600-200=400
Holding period return = Net retun/ Own Cash*100
=400/5000*100= 8%
B) Given Own cash = 8000
Margin loan = 2000
Hence interest on margin loan = 4% of 2000= 80
Return on stcok = 6% of 10000 =600
Net return = 600-80- 520
Holding period return = 520/8000*100
=6.5%
Hence the Holding period return of 6.5% will be lower at own cash investment of 8000 as compared to answer a.
The reason for decrease is increase in the value of own capital . Even though interest cost has decreased by 80, due to increase in the own cash the denominatior has increase substantially whereby reducing the holding period return on investment
c) Let the interest rate charged by Brokerage firm be x%
For part a)
interest on brokerage in case a= x% of 5000
Hence net return =600-x% of 5000
Holding period return =(600-x% of 5000)/5000
For part b)
interest on brokerage in case a= x% of 2000
Hence net return =600-x% of 2000
Holding period return =(600-x% of 2000)/8000
To compute the indifferent point
Holding period return of part a= Holding period return of part b
or (600-x% of 5000)/5000= (600-x% of 2000)/8000
or 600*8000- x% of 5000*8000= 600*5000-x% of 2000*5000
or 4800000-x% of 40000000= 3000000- x% of 10000000
or 4800000-3000000= x% of 40000000- x% of 10000000
or 1800000= x% of 30000000
or x%= 1800000/30000000
=X% = 0.06
i.e 6%
The answer would not reverse at any interest rate below 6%.At 6% Both the holding period return will be equal and any interest rate higher than 6% answer in part b will be higher than asnwer in part a.
the calculation is shown below
4% | 4% | 6% | 6% | 8% | 8% | ||
Loan amount = 5000 | Loan amount = 2000 | Loan amount = 5000 | Loan amount = 2000 | Loan amount = 5000 | Loan amount = 2000 | ||
A | Investment income | 600 | 600 | 600 | 600 | 600 | 600 |
B | Interest (Loan amount * Interest rate) | 200 | 80 | 300 | 120 | 400 | 160 |
C | Return(A-B) | 400 | 520 | 300 | 480 | 200 | 440 |
D | Own cash | 5,000 | 8,000 | 5,000 | 8,000 | 5,000 | 8,000 |
E | Holding period return ( C/D) | 8% | 7% | 6% | 6% | 4% | 6% |
