There is a one-time parallel shift in the yield curve that occurs before the next coupon payment date要怎么理解?另外investors risk is to lower interest rates是什么意思
老师,您能否详细解释一下这句话的原理: If we long a stock and short 1/delta calls the value of the portfolio does not change, when the value of the stock changes. We make money by buying the stock and lose money by selling the call options while the value of the portfolio remains unchanged. This portfolio is referred as a delta-neutral portfolio. 1)为什么通过delta-neutral hedging可以做到改变stock的values,却不改变portfolio的value? 2)为什么可以认定make money by buying the stock and lose money by selling the call options?
持有到期最后收到的本金就是固定的,那怎么会导致total return over呢?这里princial是固定的就等于par,它只能说明是one source of return并不能使total return over,为什么不选B?
查看试题 已回答包括基础视频、习题视频,声音都有大有小,声音小的就比如这道习题,带耳机调最大声才能听见。一大半人都在远程听课,视频声音那就是“产品质量”,像这道题这个小音量 那就是“质量事故”。希望金程蒸蒸日上!【其实很简单,音视频上线前统一一个音量检测标准、做好执行即可,程序也可以自动检测。】
