题目
A trader buys one wheat contract (underlying = 5,000 bushels) at a price of $3.05 per bushel. The initial margin on the contract is $4,500 and the maintenance margin is $3,750. At what price will the trader receive a maintenance margin call?
选项
A.$2.30
B.$2.90
C.$3.20
D.$3.80
答案
B
解析
The trader would have to post a margin of $4,500 at the outset and would receive a margin call if the value of this margin fell to $3,750. Assuming price will decline to PD, the trader receive a maintenance margin call, so 3.05 - PD = (4500 - 3750)/5000, PD = $2.9.交易员在开始时必须提供4500美元的保证金，如果保证金的价值下降到3750美元，就会接到追加保证金通知。假设价格将下降到每日，交易员收到维持保证金通知，因此3.05 -X=(4500 - 3750)/5000，X= 2.9美元。
