在非均衡市场投资组合套利机会存在性假设的随机市场的基础上 ,先对T -期权和均衡价格进行定义 ,对定义进行了分析和说明。利用随机分析的相关知识 ,在市场完备性条件下证明了欧式看跌和看涨期权价格相等 ,都等于均衡价格。另外 ,在相同的假设条件下 ,讨论了期权 (欧式 )的套期交易策略的选择 ,并构造性地获得了套期交易策略及其相应的计算公式。为说明问题起见 ,举例说明了如何计算得到具体的投资组合套期交易策略的表达式。
This article is based on the existence of an arbitrage about a portfolio in an disequilbrium market under the supposition of the stochastic market.
