ヾ(◍°∇°◍)ノ゙你好同学,
在合成看涨期权时,不使用买卖权平价公式,于是出现了你说的“没有-S”的情况
如以下解析所示,合成一个short call头寸,可以通过将short asset(shorting the underlying)和long bond(risk-free lending)完成。
To replicate selling a call option, combine shorting the underlying with risk-free lending. This is exactly the opposite strategy to replicate buying a call option in which the underlying is purchased with proceeds from risk-free borrowing.
