A.Trade 1
Trade 2
Trade 3
解释：
C is correct. There is a negative correlation between equities and volatility. A long volatility positions are necessary to hedge equity exposure in investment portfolios. Trade 1 is a short volatility position and will not hedge against equity positions as it requires a long volatility position. Trade 2 is also a short position in volatility; Its purpose is to charge a premium for selling volatility. This type of transaction will be carried out simultaneously with the equity sell-off, providing hedging. Trade 3 is a direct purchase of volatility through swaps, providing a pure long exposure and hedging the existing equity exposure in the portfolio.
A is incorrect. A short volatility position will not hedge the equity position since a long volatility position is needed.
B is not correct. Trading 2 is a short position in volatility; Its purpose is to charge a premium for selling volatility. This type of transaction will be sold simultaneously with the stock sell-off, therefore no hedging is provided.
知识点考察：volatility trading
从题干看出其目的是要对冲做多股票的风险敞口，而股票和波动率成反向关系，所以应该做多波动率来达到题干的目的。而trade1 2 3中只有trade 3是做多波动率的。所以选项trade 3。
This type of transaction will be carried out simultaneously with the equity sell-off, providing hedging.
