同学您好
A long risk reversal combines long call and short put on the same underlying with same expiration. 风险逆转多头结合了相同标的资产相同到期期限的看涨期权多头和看跌期权空头。例如:
If a trader believes that put implied volatility is relatively too high, compared to that for calls, a long risk reversal could be created by buying the OTM call (underpriced) and selling the OTM put (overpriced) for the same expiration. 如果交易者认为相对于看涨期权,看跌期权隐含波动率相对过高,那么在相同到期期限内买入场外交易看涨期权(定价低估)并卖出场外交易的看跌期权(定价高估),就可以构建风险逆转多头(long risk reversal= long call + short put)
However, this would create a long exposure to the underlying, which could be problematic. 然而,这将导致对标的资产的多头敞口(看涨标的资产),这可能会产生问题
