老师您好,这是GIPS上午题,我想问一下这个daily-weighted cash flows 是什么意思是modified dietz 吗?policy 里面cash flowed are weighted as of mid-month 是original dietz吗?算TWRR是不是有external cash flow才算superiod return, 然后复利起来。 但是讲义里算TWRR是先算daily return 然后复利成monthly return 然后复利成quarterly return,最后复利成year return.所以我觉得跟TWRR有large external cash flow再算sub period return有点冲突。 而且这里daily-weighted cash flow,我也不知道是讲的是modified dietz还是TWRR?谢谢
老师,这部分内容一二级学过,但是我印象不深了。您能解释一下或者把一二级中解释这个知识点的截图发给我吗?Delta for long calls is always positive: (0,1). When the option is in the money delta approximates 1. At the money, delta=0.5. Delta for long puts is always negative: (-1, 0). When the option is in the money delta approximates -1. At the money, delta=-0.5. 我不太明白为啥underlying stock涨了,call option也会涨?underlying stock涨了, put option会降低?
