老师好, 有一个关于VaR计算的题。 Assume we calculate a one-week VaR for a natural gas position by rescaling the daily VaR using the square root rule. Let us now assume that we determine the “true” gas price process to be mean reverting and recalculate the VaR. Which of the following statements is true? 选项见图片。 这题为什么选A? 看答案也不懂, 天然气价格因为均值回归负相关? 为什么? 请老师解释一下。
