金融市场与产品的讲义P146，远期Delta都是1。解析里的gong'si公式shi是期货。而且题目中也没告诉r。不理解
NO.PZ2016082404000026问题如下 The vinyielof asset is 10% per annum. Whis the lta of a long forwarcontraon the asset with six months to maturity? 0.95 1.00 1.05 Cannot termine without aitioninformation ANSWER: AThe lta of a long forwarcontrais e−r∗τ=e−0.10×0.5=0.95.e^{-r\ast\tau}=e^{-0.10\times0.5}=0.95.e−r∗τ=e−0.10×0.5=0.95. 这个没有看出来为什么lt是e 的分红率乘以时间，不应该是无风险报酬率减分红吗
