It shows that traditional finance theory based on the assumptions of normal return distribution, random walk, and independence cannot accurately characterize the price behavior ; while with the hypothesis of fractal capital market, non - normality, fractional brownian motion, and the long - term memory of the financial time series, the behavior of the actual stock price can be characterized well
研究表明，基於有效市場的傳統理論假設:正態分佈、隨機游動與獨立性並不能準確刻化股票價格行為，而基於分形市場的理論假設，非正態分佈、分數布朗運動與長期記憶性能夠很好描述實際資本市場的價格行為。 -
Based on the fractals of the capital market, this paper derives a fractional geometric brownian motion model for the stock price. this paper constructs a formula for option pricing on the basis of the fractional brownian motion model. on the one hand, this paper draws on the latest researches in this field : the explicit formula for european option pricing ? the fractional brownian motion formula for option pricing ; on the other hand, the analytical solution is derived through the monte carlo simulation
基於資本市場的分形特性，本文接著推導出股票價格變化的幾何分數布朗運動模型;隨后，在該模型的基礎上，本文研究了在分數布朗運動環境下的期權定價模型，一方面引用了國際上最新的研究成果:在分數black - scholes完全市場下，歐式期權定價的顯式公式-分數black - scholes期權定價公式;另一方面，又運用蒙特卡羅模擬法，通過模擬股票價格變化的路徑並進行貼現，得出了歐式期權價格的數值解。
