英文摘要:
We develop series expansions in powers of $q^{-1}$ and $q^{-1/2}$ of solutions of the equation $\\psi(z) = q$, where $\\psi(z)$ is the Laplace exponent of a hyperexponential L\\\'{e}vy process. As a direct consequence we derive analytic expressions for the prices of European call and put options and their Greeks (Theta, Delta, and Gamma) and a full asymptotic expansion of the short-time Black-Scholes at-the-money implied volatility. Further we demonstrate how the speed of numerical algorithms for pricing exotic options, which are based on the Laplace transform, may be increased.

中文摘要:
我们对方程$\\ psi(z)=q$的解进行了幂次为$q^{-1}$和$q^{-1/2}$的级数展开,其中$\\ psi(z)$是超指数L{e}vy过程的拉普拉斯指数。作为直接结果,我们推导出了欧洲看涨期权和看跌期权及其希腊期权(θ、δ和γ)价格的解析表达式,以及货币隐含波动率下短期Black-Scholes的完全渐近展开。此外,我们还展示了如何提高基于拉普拉斯变换的奇异期权定价数值算法的速度。
