ヾ(◍°∇°◍)ノ゙你好同学,
A hedged portfolio指的是:现有的投资状态将所有的风险对冲掉,没有波动和风险,可以获得无风险收益率。
题目中是将equity index和期货合约组合起来构成的“hedged portfolio”
(原版书定义)Derivatives usually take their values from the underlying by constructing a hypothetical combination of the derivatives and the underlyings that eliminates risk. This combination is typically called a hedge portfolio.A derivative’s value is the price of the derivative that forces the hedge portfolio to earn the risk-free rate.
