为何加上仓储成本后，期货价格大于现货价格？

A portfolio manager invests $100 million in a 5-year inverse floater paying 18% – 2 × LIBOR. Assume that the modified duration of a 6% 5-year bond is 4.5 years, and the inverse floater is just before a reset day. The worst change in yields at the 95% level over a month is 0.66%. What is the VaR of this inverse floater at the 95% level over a month? 此题把18%-2L拆分的话不也应是（3*6）%-2L么？为什么是拆成了3*6%-2L？那这样两边怎么能相等？ 谢谢

这个案例说的稀里糊涂

这一题的视频解析讲错了

每日标准差是4.27，那么七天的标准差怎么算呢？

＂很大额的交易＂说的和课件不一致

为什么一年是256天而不是365天哪？

这道题那个置信水平提高vaR的误差更大还是不明白

Bond Yield Maturity 年化Standard Deviation Exposure(million) A 5% 2 5% USD 25.00 B 3% 13 12% USD 75.00 The correlation between the two returns is 0.25. From a risk management perspective, what is the gain from diversification for a VaR estimated at the 95% level for the next 10 days? Assume there are 250 trading days in a year. 计算过程没问题，但没明白为什么在算分散化VaR时，前面都是按单位1million统一的，而算这个时根号里的25M 75M却变成了0.25 0.75 按W的单位来算？那这样计算前后单位不统一怎么可以比大小呢？ 谢谢。

老师，这道题我能否假设前后执行价格不变，先根据题干前面给的数据算出k，根据分红，算出分红率，把K和分红率再带到新条件（后面给出的数据）中，算出新的期权价格？我这样算的结果和答案一样，约等于1.95
