C is correct.
考点：stock index futures定价

老师，这里不是让求零时刻的定价吗，future是盯市，价值为零，怎么答案是按照求小t时刻的时间计算呢？

1,351.23 1,348.76 C is correct. 考点stoinx futures定价 解析 F0(T)=1350×e(0.25%−0.8%)×(60/360)=1,348.76F_0(T)=1350\times e^{(0.25\%-0.8\%)}\times^{(60/360)}=1,348.76F0(T)=1350×e(0.25%−0.8%)×(60/360)=1,348.76实在不好意思，想问下这道题计算器怎么按………因为0.25小于0.8，开方会报错啊……

NO.PZ2019010402000002 有点忘了，为什么分红的0.8%也要折现呢。。
