Using short-term futures to hedge a long-term risk exposure by replacing them with longer-term contracts shortly before they expire 用短期期货对冲长期合同的风险去短暂地用长期合同代替它们,它们不就是长期合同吗?用长期合同去代替长期合同,去代替它们本身?
正确的说法不该是Using short-term futures to hedge a long-term risk exposure by replacing them with short term future shortly before they expire.?
