摘要
提出了股价的分形跳跃扩散模型,求出了该模型的解,证明了分形跳跃扩散过程的It公式。在分形跳跃扩散市场是无套利的情况下,找到了一个等价鞅测定,获得了欧式期权定价公式。
A fractional jump-diffusion model of stock price was constructed, the solution of the model was obtained and the Ito formula of fractional jump-diffusion processes was proved, under the condition of fractional market of no arbitrage environment, an equivalent martingale measure was founded and the pricing formula was obtained for European option with a constant dividend yield.
