期货交易追加保证金
An investor establishes a short position in a futures contract on Day0 when the price per contract is $100. The investor deposits $5 per contract to meet the initial margin requirement. The maintenance margin requirement per contract is $3. The Day 1 settlement price that would require the investor deposit additional funds on Day 2 equal to $4 per contract is closest to:
A.        $97.00.
B.        $103.00.
C.        $104.00.
 
答案:C
Additional margin must be deposited to bring the ending balance up to the initial margin requirement. The investor must deposit $4; therefore, the margin balance on Day 1 is -$4, which would result if the price of the contract was $104.
  • 对于期货交易来讲,如果有亏损,将则亏损额从保证金帐户中减去,如果此时的余额小于维持保证金,则要追加保证金,并回复到初始保证金。
  • 另外,如果是Long,则价格下跌时,有亏损;对于Short来讲,则价格上升时,有亏损。所以,我们在做题时,要首先区分是Long还是Short。
  • 本题是Short,如果追加保证金,肯定是价格上涨了,上涨的部分就是追加的部分,现在追加了4元,而原价格为100,则说明价格现在为104。
