Option pricing for generalized distributions

The Black Scholes formula has been widely used to price financial instruments. The derivation of this formula is based on the assumption of lognormally distributed returns which is often in poor agreement with actual data. An option pricing formula based on the generalized beta of the second kind (GB2) is presented. This formula includes the Black Scholes formula as a special case and accommodates a wide variety of nonlognormally distributed returns. The sensitivity of option values to departures from the skewness and kurtosis associated with the lognormal distribution is investigated.     

Exchange option in a two-state Poisson CAPM

In this paper we derive the pricing formula for the exchange option value in a two-state Poisson CAPM. A two-state Poisson CAPM models the stochastic market environment. We also provide examples and graphs to illustrate our result.     

行业竞争与公司成本黏性:基于实物期权视角

基于实物期权理论的分析表明,公司在面临业务量下降时管理层未能够及时有效地执行清算期权,使得现有资源配置与当期业务量变化不相匹配,将导致公司成本黏性.实证研究发现,激烈的行业竞争能够促使管理层更有效地执行清算期权,在面临业务量下降时及时地对现有资源进行处置或改变用途,从而显著降低公司成本黏性.进一步的分析显示,行业竞争对公司成本黏性的影响主要体现在宏观经济高增长期、行业景气度高以及高成长性公司样本.文章的研究结论有助于揭示公司管理层的成本管理行为这一“黑箱”.

基于银行监管资本的存款保险定价研究

结合存款保险定价的期权定价法和期望损失定价法,提出了利用银行破产时被保险存款的期望损失来定价存款保险的新思路,该方法的特点是存款保险定价不仅仅与银行资产的风险和收益有关,而且与银行资本持有状况和存款的参保比率有密切关系.通过理论推导得到了存款保险定价公式.运用极大似然估计方法与测算原理,实证研究了其敏感性、可行性与合理...     

期权“净购买压力”的隐含信息

使用50ETF期权的高频数据,研究“净购买压力”指标对指数方向性和波动性变化的预测能力,并比较不同加总方法、看涨看跌、不同在值程度的期权以及非对称的“净购买压力”指标隐含信息的差异性.本文发现,50ETF期权“净购买压力”指标隐含着标的指数方向性和波动性的变化信息.在预测指数变化方向时,Delta加总的“净购买压力”隐含的信息已包含在简单加总的指标之中,看涨、看跌期权以及不同在值程度的期权在信息含量上存在差异性.在预测指数波动性时,使用简单加总和使用Gamma、Vega加总的“净购买压力”指标均隐含着未来市场的波动率信息,平值和虚值期权的“净购买压力”指标对波动率具有更强的预测能力.同时,“净购买压力”的隐含信息存在非对称特征.     

应用混合神经网络和遗传算法的期权价格预测模型

隐含波动率是指在市场中观察的期权价格所蕴涵的波动率.提出了一种加权的隐含波动率作为混合神经网络的输入变量,建立了混合神经网络和遗传算法相结合的期权价格预测模型,通过遗传算法来优化神经网络的结构和获得隐含波动率的权重.在对香港金融衍生品市场的实证中表明,本文模型在预测结果上要优于传统的Black-Scholes模型.

Conditional expectation determination based on the J-process using Malliavin calculus applied to pricing American options

The aim of our paper is to elaborate a theoretical methodology based on the Malliavin calculus to calculate the following conditional expectation (P_t(X_t)|(X_s)) for s≤t where the only state variable follows a J-process [Jerbi Y. A new closed-form solution as an extension of the Black—Scholes formula allowing smile curve plotting. Quant Finance. 2013; Online First Article. doi:10.1080/14697688.2012.762458]. The theoretical results are applied to the American option pricing, consisting of an extension of the work of Bally et al. [Pricing and hedging American options by Monte Carlo methods using a Malliavin calculus approach. Monte Carlo Methods Appl. 2005;11-2:97–133], as well as the J-process (with additional parameters λ and θ) is an extension of the Wiener process. The introduction of the aforesaid parameters induces skewness and kurtosis effects, i.e. smile curve allowing to fit with the reality of financial market. In his work Jerbi [Jerbi Y. A new closed-form solution as an extension of the Black–-Scholes formula allowing smile curve plotting. Quant Finance. 2013; Online First Article. doi:10.1080/14697688.2012.762458] showed that the use of the J-process is equivalent to the use of a stochastic volatility model based on the Wiener process as in Heston's. The present work consists on extending this result to the American options. We studied the influence of the parameters λ and θ on the American option price and we find empirical results fitting with the options theory.
