套利对冲策略与波动率微笑的另一种解释

Arbitrage hedging strategy and one more explanation of the volatility smile

Mikhail Martynov, Olga Rozanova

摘要:

我们提出了一个明确的套期保值策略,它能够证明市场的套利性,至少包含两个资产取决于同一个随机因素。隐含的布莱克-斯科尔斯波动率,考虑到期权价格的图形的形式计算,与我们的策略有关,证明了观察数据固有的“偏态”。

英文摘要:

We present an explicit hedging strategy, which enables to prove arbitrageness of market incorporating at least two assets depending on the same random factor. The implied Black-Scholes volatility, computed taking into account the form of the graph of the option price, related to our strategy, demonstrates the "skewness" inherent to the observational data.
