解释:
老师好,这道题的i项,之前答疑老师说volatility也可以有波动减小的假设,可是按照公式,volatility不应该是恒定不变的吗?
这对应的是哪一个知识点?在ppt哪里?
II only. Both I anII. Neither I nor II. Time-pennt volatility mols are very flexible ancincorporate increasing, creasing, anconstant short-term rate volatilities between perio. This flexibility is useful for valuing interest rate caps anfloors because there is a potentipayout eaperio so the flexibility of changing interest rates is more appropriate thapplying a constant volatility mol. 我想问一下解析里多钱“constant short term rate volatilities between perio”怎么理解呢?63题中,不是还提到V mol的volatility是cresing的吗?解析所说的constant是指?
没看懂这道题目的意思
