本文的前半部分旨在对离散和连续时间期权定价进行简短的调查。在第二部分中,我们发展了新的概念,并得出了新的结果,期权定价在一个广义的二项式模型与随机上升和下降,其特点是等价的投资组合,交易策略,和看涨期权的估值。受Mandelbrot-Taylor Paretian稳定模型的启发,我们应用广义二项式模型得到了从属股票价格过程的限价看涨估值公式。
The first half of the paper is intended as a short survey on discrete- and continuous-time option pricing. In the second part, we develop new concepts and derive new results for option valuations within a generalized binomialmodelwith random upturns and downturns, characterizing the equivalent portfolio, the trading strategy, and the call option valuation. Motivated by the Mandelbrot-Taylor Paretian stable model for stock returns we apply the generalized binomial model to obtain - in the limit - call valuation formulae for subordinated stock-price processes.
