问题 单项选择题

棉花期权的多空双方进行期转现交易,多头开仓价格为10210元/吨,空头开仓价格为10630元/吨,双方协议以10450元/吨平仓,以10400元/吨进行交收,空头可节约交割成本200元/吨,空头进行期转现交易比不进行期转现交易()。

A.节省180元/吨

B.多支付50/吨

C.节省150元/吨

D.多支付230元/吨

答案

参考答案:C

解析:由题意,期转现后,多头购入棉花实际价格为10400-(10450-10210)=10160(元/吨),空头销售棉花实际价格为10400+(10630-10450)=10580(元/吨)。由上可知,空头实际销售价格比开仓价格少了50元/吨,但其节约了成本200元/吨,综合起来仍比不进行期转现交易节约了150元/吨,期转现对其有利。
