Answer:
initial margin = $1500
margin call will be issued when the stock price reaches at $34.62
Explanation:
given data
sell = 100 shares
market price = $30 per share
to find out
How much in cash put brokerage account and How high price of stock go before get margin call
solution
we know here value of investment that is
value of investment = shares × market price
value of investment = 100 × 30
value of investment = $3000
and Initial Margin is = value of investment × margin requirement
Initial Margin is = 3000 × 50%
initial margin = $1500
and
Total Assets is = value of investment + initial margin
Total Assets is = $3000 + $1500
Total Assets is = $4500
so
total liability = share × Share Price
total liability = 100 P
here P is Share Price
so
Net Worth = Total Assets - Total Liabilities
Net Worth = 4500 - 100 P
and
Maintenance Margin =
30 % =
0.30 × 100 P = 4,500 - 100 P
P = 34.62
so margin call will be issued when the stock price reaches at $34.62
