PROBLEMS
1. An investor purchased on margin Orange Computer for $30
a share. The stock’s price subsequently increased to $50 a
share at which time the investor sold the stock. If the
margin requirement were 60 percent and the interest rate on
borrowed funds were 7 percent, what would be the percentage
earned on the investor’s funds (excluding commissions)?
What would have been the return if the investor had not
bought the stock on margin?
2. An investor bought on margin 100 shares of Copier Corp.
for $85 a share. The firm paid an annual dividend of $4 a
share; the margin requirement was 60 percent with an
interest rate of 8 percent on borrowed funds, and
commissions on the purchase and sale were $75. The price of
the stock rose to $120 in one year.
a. What is the percentage earned on the investment if the
stock is bought for cash (i.e., the investor did not use

b. What is the percentage earned on the investment if the
stock is bought on margin?
3. An investor sells 100 shares short at $43. The sale
requires a margin deposit equal to 60 percent of the
proceeds of the sale. If the investor closes the position

of the stock was $27, what would have been the percent
earned or lost on the position?
4. An investor sells 100 shares short at $43. The sale
