同學你好,
如果yield curve不變,這個時候convexity對我是沒用的,所以我sell convexity是更好的選擇,
而他現(xiàn)在是要sell long-term bond所以他是在賣convexity,并買入option,這相當于long convexity所以他會有一個loss
option相當于讓你有一個convexity,所以他有漲的多跌的少的特點。
Options are added in anticipation of a significant change in rates. If the yield curve remains stable, the portfolio will experience a loss from both the initial purchase price of the options and the foregone interest income on the liquidated bonds.
因為有convexity的特點,所以利率變化時會給我?guī)頋q的多跌的少的效果。如果收益率曲線不動,組合買option就是沒意義的,這個時候我買convexity是沒有用的,所以我花了冤枉錢,另外我還損失了手里持有l(wèi)ong-term bond給我?guī)淼睦⑹找妗?/p>
