Answer:
a) - 11.11%
b) - 13.88%
Step-by-step explanation:
Given:
Number of shares purchased = 500
Cost of per share = $ 36
Selling cost of the shares = $ 32
Initial marginal requirement = 80 %
Maintenance margin = 30 %
Now,
the Holding period return without using the margin = ($ 32 - $ 36) / $ 36 = - 11.11%
also,
Holding period return using the margin = ($ 32 - $ 36) / ($ 36 × 0.8) = - 13.88%
