确定美式一般类衍生品到期提前行使边界位置的统一方法

A unified approach to determining the early exercise boundary position at expiry for American style of general class of derivatives

Tomas Bokes

摘要:

本文提出了一种新的计算到期提前行使边界的方法。我们使用一个公式来为美式一般衍生品定价,该公式表示为欧式衍生品的价值和所谓的美式溢价之和。我们利用后一个表达式计算出了到期提前行使边界的解析公式。方法适用于美国风格的普通香草,亚洲和回望期权产生相同的结果与已知的值。选择美国风格的衍生策略的结果进行比较与PSOR方法计算的限制。

英文摘要:

In this paper, we present a new method for calculating the limit of early exercise boundary at expiry. We price American style of general derivative using a formula expressed as a sum of the value of European style of derivative and so called American premium. We use the latter expression to calculate an analytic formula for limit of early exercise boundary at expiry. Method applied on American style plain vanilla, Asian and lookback options yields identical results with already known values. Results for selected American style of derivative strategies are compared with limits calculated by the PSOR method.
