Answer and Explanation:
The computation is shown below:-
a. Margin
Equity account = Number of shares × Price per share
= 400 × $28
= $11,200
Margin = Purchase price - Money borrowed from the broker
= $11,200 - $3,000
= $8,200
b. Remaining margin
Equity account = Number of shares × Price per share
= 400 × $18
= $7,200
Total liability = Borrowed amount × 1.12
= $3,000 × 1.12
= $3,360
Remaining margin = Equity value - Liability to the broker
= $7,200 - $3,360
= $3,840
Remaining margin ratio = Remaining margin ÷ Equity value
= $3,840 ÷ $7,200
= 53.33%
c. As per the information maintenance margin requires 30%
No, maintenance margin requires 30% and the remaining martin is 53.33% then it will no margin calls
d. Rate of return
Rate of return = (Return - Initial inventment) ÷ Initial investment
= ($3,840 - $8,200) ÷ $8,200
= -53.17%
