衍生

It was supposed that the dynamic moving process of the stock price and the return was driven by Geometry Brownian Motion and the lognormal distribution respectively. Takinginto account the riskneutral environment, we got a closedform analytical formula for deferred arithmetic asian options by the method of Taylor expansion of the stochastic integral formula within the terminal payoff. Furthermore, with the series definition of the definite integral, we transferred the continuous problem into a discrete one which is simpleenough to figure out. Meanwhile we tested the accuracy of the formula with the Monte Carlo simulation as a benchmark and the result shows that the formula can be utilized to price the related financial derivatives.

在标的价格服从几何布朗运动、收益服从对数正态分布的前提下，通过风险中性定价原理，对到期损益中的随机积分进行任意次Taylor近似，并由级数定义将此连续问题离散化，给出了延期算术平均亚式期权封闭形式的解析定价公式，并与Monte Carlo模拟得到的价格作为标尺对得到的公式进行精确性检验，结果表明，所得公式可以应用到金融实务中对此类衍生品定价中。

Bear in mind also that the outstanding notional stock of derivatives has soared to more than $1/2 quadrillion over this horizon, representing an extra $1.7 million haystack in which to search for the poisoned needle of mathematically-abstruse, systemic risk for each and every, readily-valued, new ounce of metal brought laboriously up from the Stygian gloom and into the broad light of day.

还有一点也要引起重视，衍生品市场的名义净持仓已增加到了500万亿美金以上，这相当于在价值170万美元的干草堆中寻找每一根针鼻那么大的金子，也就是不辞辛劳、苦苦搜索那每一盎司新开采出来的黄金，这些玩意儿被人们从黑暗的地狱中找出来，现如今终于来到光天化日之下。
