不仅仅这个情况吧

NO.PZ202212300200001702 问题如下 termine unr whcircumstances the carry trawill not execute CorreAnswer: Carry tra is notexecutewhen the uncovereinterest rate parity hol.In this case, theinterest rate fferentiis completely offset the preciation of thecurrency, making carry tra meaningless. 老师好，1）这题能否从Carry tra不适合在市场波动大的条件下执行这个角度出发回答？还是一定要回答到carry tra在uncover IRP成立的情况下不适合执行？因为题干给的表格是各个currenpair的波动率，如果按照李老师给的框架 原理+证据+结论，从uncover IRP成立，出发似乎很难在题干中找到证据（题目的解答里也没有从题干中找证据）2）如果可以从波动率出发我下面这样回答可以吗？Carry tra profit=yielof high yielcurrenA - yielof low yielcurrenB - foregin exchange rate change of A/Carry tra is not suitable for volatile maket, sinforeging exchange rate cline of B against A will rece, or even offset the profit from interest rate spreaGiven thcurrenpair of USEUR with the highest impilevolatility(9.5%), so even though yielof EUR(0.11%) is higher thyielof US0.05%), carry tra will not executefor this currenpair.主要对这几个细节没有把握1）carry tra profit 的公式中，foregin exchange rate change of A/B 这样的描述可否2）“sinforeging exchange rate cline of B against A will rece,” 这句，对于B相对于A贬值的描述是否对。
