英文摘要:
This article considers the pricing and hedging of a call option when liquidity matters, that is, either for a large nominal or for an illiquid underlying asset. In practice, as opposed to the classical assumptions of a price-taking agent in a frictionless market, traders cannot be perfectly hedged because of execution costs and market impact. They indeed face a trade-off between hedging errors and costs that can be solved by using stochastic optimal control. Our modelling framework, which is inspired by the recent literature on optimal execution, makes it possible to account for both execution costs and the lasting market impact of trades. Prices are obtained through the indifference pricing approach. Numerical examples are provided, along with comparisons to standard methods.

中文摘要:
本文考虑了在流动性重要的情况下,看涨期权的定价和套期保值,即,对于大额名义资产或非流动性标的资产。在实践中,与无摩擦市场中价格接受代理的经典假设相反,由于执行成本和市场影响,交易者无法完全对冲。它们确实面临着套期保值误差和成本之间的权衡,这可以通过使用随机最优控制来解决。我们的建模框架受最近有关最优执行的文献启发,可以考虑执行成本和交易的持久市场影响。价格是通过无差异定价方法获得的。文中给出了数值例子,并与标准方法进行了比较。
