单选题
Consider the following bonds:
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.
老师这道题整个都不明白,视频解析讲的不明白,最后求组合var为什么不是用网课讲的组合求var的两种方式呢?这又是什么方法?
