英文摘要:
We introduce a simple stochastic volatility model, whose novelty consists in taking into account hitting times of the asset price, and study the optimal stopping problem corresponding to a put option whose time horizon (after the asset price hits a certain level) is exponentially distributed. We obtain explicit optimal stopping rules in various cases one of which is interestingly complex because of an unexpected disconnected continuation region. Finally, we discuss in detail how these stopping rules could be used for trading an American put when the trader expects a market drop in the near future.

中文摘要:
我们引入了一个简单的随机波动率模型,其新颖之处在于考虑了资产价格的击中次数,并研究了时间范围(在资产价格达到一定水平后)呈指数分布的看跌期权的最优停止问题。在各种情况下,我们得到了显式的最优停止规则,其中一个有趣的是,由于意外的断开连续区域,它非常复杂。最后,我们详细讨论了当交易员预期近期市场下跌时,这些止损规则如何用于美国看跌期权的交易。
