Funds
The generalization implied by problems 1 and 2 is that if the margin requirement is small
(e.g., 25 percent), then the potential return or loss on the investor’s funds (i.e., the margin)
is magnified for a given change in the stock’s price.
2-3. Cost of 100 shares: $10,000
a. profit on the stock: $11,200 – $10,000 = $1,200
b. loss on the stock: $9,000 – $10,000 = ($1,000)
c. loss on the stock: $6,000 – $10,000 = ($4,000)
2-4. This problem adds the interest that must be paid on the borrowed funds.
a. The cost of the shares is 100 x $35 = $3,500.
b. Investor B borrows $3,500 x 0.4 = $1,400 and has
c. The capital gain for both investors is
d. The percentage returns differ because investor A
2-5. This is a much more comprehensive problem that considers not only the change in the
security’s price but also commissions, dividends received, and interest on any loans
resulting from buying the stock on margin. The instructor may wish to work through an
example of the holding period return that encompasses dividends received, commissions
paid, and any interest paid on a margin account before assigning this problem.
