C is incorrect because derivatives are not needed to copy strategies that can be implemented with the underlying on a standalone basis. Rather, derivatives can be used to create strategies that cannot be implemented with the underlying alone. Simultaneously taking long positions in multiple highly liquid fixed-income securities is a strategy that can be implemented with the underlying securities on a standalone basis.这个解释没看懂，尤其是 on a standalone basis.是啥意思呢
查看试题 已回答老师，官网mock题第19题，这个被任命为合规官员的人不是还同时从事了co-investment, 冲刺笔记上写说合规官员应该独立予投资和运营人员，那这个不应该就是voilate，应该选C吗？
老师，reading28 第41题，这道题考察什么知识点，为什么two-standard-deviation increase in the steepness factor直接就是-0.3015%×2呢，为什么是负数呢，是因为是标准差的increase吗 ？表中level、steepness、curvature的正负号表示什么
老师，CME的官网模考题，这一题说要用longest data history data，太长时间数据不是更容易涵盖multiple regime, 进而导致nonstationarity吗？为什么反倒说是assurance of stationarity
