英文摘要:
We consider call option prices in diffusion models close to expiry, in an asymptotic regime (\"moderately out of the money\") that interpolates between the well-studied cases of at-the-money options and out-of-the-money fixed-strike options. First and higher order small-time moderate deviation estimates of call prices and implied volatility are obtained. The expansions involve only simple expressions of the model parameters, and we show in detail how to calculate them for generic local and stochastic volatility models. Some numerical examples for the Heston model illustrate the accuracy of our results.

中文摘要:
我们考虑了接近到期的扩散模型中的看涨期权价格,在一个渐进机制(“适度缺钱”)中,在经过充分研究的非现金期权和缺钱固定行使期权之间进行插值。得到了看涨期权价格和隐含波动率的一阶和高阶小时中偏差估计。展开式只涉及模型参数的简单表达式,我们详细介绍了如何计算通用局部和随机波动率模型的参数。赫斯顿模型的一些数值例子说明了我们结果的准确性。
