个人IPS 2015年第8题a问题第一小题，fi增加会降低portfolio的风险，但是为什么会降低financial market risk呢？只有增加diversification才能降低mkt risk吧，这题的答案没懂

r31 第7题的答案是，sale， monetazing 和hedge，我答得是用swap option和futures，请问是哪里错了？题目问的是single common stock的diversify的方法啊

r31 第12题，关于税的部分，答案写由于可以在tax 上升之前操作，所以可以满足hill的objective（包括minimizing tax），但是这个recapitalization的strategy分两次操作，第二次就是在税上升之后了，为什么答案还是说可以满足呢

第6题的statement3没有看懂，可以解释一下是什么意思吗？

29 Stafford is a portfolio manager for a specialized real estate mutual fund. Her firm clearly describes in the fund’s prospectus its soft dollar policies. Stafford decides that entering the CFA Program will enhance her investment decisionmaking skill and decides to use the fund’s soft dollar account to pay the registration and exam fees for the CFA Program. Which of the following statements is most likely correct? A Stafford did not violate the Code and Standards because the prospectus informed investors of the fund’s soft dollar policies. B Stafford violated the Code and Standards because improving her investment skills is not a reasonable use of the soft dollar account. C Stafford violated the Code and Standards because the CFA Program does not meet the definition of research allowed to be purchased with brokerage commissions. 这道题老师讲一下为啥选项b不能选吧。。。
