ヾ(◍°∇°◍)ノ゙你好同学,
套利是在“低买高卖”
题目说:In the illustration, Sousa is also asked to describe related arbitrage positions to use if the call option is overpriced relative to the model. 题目的意思是call在市场上被高估,于是应该在市场上卖出call,short call
于是对应的是低卖,但是市场上不能直接买入call,于是用其他投资工具合成一个“call”
这也是解析的意思:You should sell (write) the overpriced call option and then go long (buy) the replicating portfolio for a call option.
