同学你好,
如果yield curve不变,这个时候convexity对我是没用的,所以我sell convexity是更好的选择,
而他现在是要sell long-term bond所以他是在卖convexity,并买入option,这相当于long convexity所以他会有一个loss
option相当于让你有一个convexity,所以他有涨的多跌的少的特点。
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.
因为有convexity的特点,所以利率变化时会给我带来涨的多跌的少的效果。如果收益率曲线不动,组合买option就是没意义的,这个时候我买convexity是没有用的,所以我花了冤枉钱,另外我还损失了手里持有long-term bond给我带来的利息收益。
