Q1，原文只是说doing Research，没说直接按新的策略就为投资者交易了呀？

HC model （US和IFRS共有）& Revaluation & FV（IFRS才有，invest property）。老师在财报中是不是USGAAP只有HC model，而IFRS有Revaluation和FVmodel去衡量PP&E和invesment property

所以第二题应该回答到哪些点才会有可观的分数呢？解析视频没有讲。

第一道题要算出1.495%,才能满分是吗？

Q2，还是没理解怎么就影响了独立客观性，独立客观是指专业性的判断吧，他去参加路演怎么就影响他的独立客观了？

PDF里没看见7、8、9题，是不重要还是漏了？

Q6，这种类似券商对其它公司的评级调整，也算重大非公开信息吗？又不是评级机构

第三题问的是trading costs，为什么也可以回答管理费？

前两题我回答的时候没有列出解析里的公式，但还是把这些return的关系说明了一下可以吗？1. USD is depreciated. The return in GBP is 15% that is lower than 19.5% denominated in USD. It means extra return is realized in currency conversion due to depreciation in USD. 2. The foreign-currency return is negative. Since EUR appreciated 5% relative to USD and portfolio B holds assets denominated in EUR, the portfolio return in USD is supposed to be at least 5% if foreign-currency return is not negative. However, the actual return in USD is 0%, which indicates negative return in foreign currency.

When calculate E (R) of bond portfolio, which method we use?(1+ yield income + roll down + yield change return + spread change return) * (1+Rfx) -1 or yield income + roll down + yield change return + spread change return + currency return?
