原生资产

确定原生资产的隐含波动率无论是在理论还是实际应用上都有重要意义。

Identifying the implied volatility of underlying assets is very important for both theoretical and practical applications .

第四章，主要结合回望期权的买入按低价，卖出按高价的特点对重置期权进行创新。应用原生资产价格的最高与最低概率分布主要得出了这种更复杂重置看涨期权、看跌期权的定价公式。

In chapter 4 , one innovations of the single-point reset options are provided by considering look back options " buying at lowest price and selling at highest price " .

最后分别分析五种典型变量（包括原生资产现价、敲定价格、波动率、无风险利率、股息）对美式期权价格的影响。

Finally , we analyze the relationship among different parameters ( including exercise price , volatility , risk-free interest rate , dividend . etc. ) and the premium of American options .

第三节着重研究了单点水平重置敲定价格的重置期权的定价问题，应用原生资产价格的最高与最低概率分布给出单点水平下重置看涨期权、看跌期权的定价公式。

In section three , this thesis discusses reset options pricing of single-point-level resetting strike price and gives single-point-level reset call options and put options pricing formulas by using distribution of maximum and minimum asset price .
