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?

Sarah Ko的case在考试时也要算出概率才能得满分吗？

最后一期为什么只涉及到本金，不应该还有最后一笔利息吗？

为什么算BPVt的时候要乘以0.01%呢？还有BPVctd/CFctd就是这张债券标准的期货价格对吧？

老师题目中basis是多少会给的吧。

老师，这个basis，谁实际上用了非usd谁支付非usd利息谁就pay basis对吧。就等于从银行贷usd的那方支付basis。相当于肯定是可怜的非美国公司来支付呗。这么记可以吧。

请问RRTTLLU,RR属于change in goal，TTLLU属于 constrain对吗
