market risk: correlation and volatility of correlation
FRM II
Market Risk Measurement And Management
题目关于: correlation and correlation volatility 之间的关系, 应该是正相关没错. 然后题目选项: A.correlation and correlation volatility are highest for recessions. D. correlations are highest for recessions, and correlation volatilit is highest or normal periods. 为什么呢？讲义里不也提到correlation volatility是在worse eco states情况下最高啊
