Equity market
1. Margin account. Suppose the margin requirement is as follows.
p>=\$2: 50% margin
\$1.75<=P<\$2: 40% margin
\$1.50<=P<\$1.75: 20% Margin
P<\$1.50: No margin
A client buys 1,000 shares of ABC on margin at \$1.8. What is the cash put up by the client? If
the prices falls to \$1.6, what is the cash needed to put into the margin account?
Solution: The client put up \$1080. If the price falls to \$1.6, he will put \$400 into the margin
account.
Client buys 1,000 shares of ABC on margin at \$1.8
Cost: \$1,800=1000*1.8
Margin loan @ 40%: 720=1800*40%
Margin: ie., cash put up by client: \$1,080=1800-720
If price falls to \$1.60
New Value: \$1,600=1000*1.6
Margin Loan @ 20%: 320=1600*20%
Current equity: \$ 880 =original margin-loss in equity
=1080-1000*(1.8-1.6)
Margin Call, ie., extra cash needed \$ 400
=new value-new margin loan-current
equity=1600-320-880
2. Short selling. Suppose that minimum credit for short sales is as follows.
P>\$2 150% of market value
A Client wants to sell 1,000 shares of ABC at \$10. What is the minimum margin required? If
