英文摘要:
In the classical model of stock prices which is assumed to be Geometric Brownian motion, the drift and the volatility of the prices are held constant. However, in reality, the volatility does vary. In quantitative finance, the Heston model has been successfully used where the volatility is expressed as a stochastic differential equation. In addition, we consider a regime switching model where the stock volatility dynamics depends on an underlying process which is possibly a non-Markov pure jump process. Under this model assumption, we find the locally risk minimizing pricing of European type vanilla options. The price function is shown to satisfy a Heston type PDE.

中文摘要:
在假设为几何布朗运动的经典股票价格模型中,价格的漂移和波动保持不变。然而,在现实中,波动性确实有所不同。在定量金融中,赫斯顿模型已成功地用于将波动率表示为随机微分方程的情况。此外,我们考虑了一个制度转换模型,其中股票波动率动态取决于一个潜在的过程,这可能是一个非马尔可夫纯跳跃过程。在此模型假设下,我们得到了欧式香草期权的局部风险最小化定价。价格函数满足赫斯顿型偏微分方程。
