| 摘 要： | 讨论了股票价格过程遵循几何分式B row n运动的欧式期权定价.由于该过程存在套利机会使得传统的期权定价方法(如资本资产定价模型(CAPM),套利定价模型(APT),动态均衡定价理论(DEPT))不可能对该期权定价.利用保险精算定价法,在对市场无其它任何假设条件下,获得了欧式期权的定价公式.并讨论了在有效期内股票支付已知红利和红利率的推广公式. |

| Abstract: | The pricing European option on a stock whose price process is driven by geometric fractional Brownian motion is considered.Existing arbitrage opportunities for these process shows that option pricing is not possible with traditional financial asset pricing methods,such as capital asset pricing model,arbitrage pricing theory,dynamic equitable pricing theory.In this paper,the formulas of the pricing European option are obtained by insurance actuary pricing without any other market assumption.Then,the expand formulas are discussed under payment of a given stock dividends and stock yields during the effective date. |
| Keywords: | Black-Schole formula geometric fractional Brownian motion insurance actuary pricing option pricing |
