چکیده

We propose a new method to compute option prices based on GARCH models. In an incomplete market framework, we allow for the volatility of asset return to differ from the volatility of the pricing process and obtain adequate pricing results. We investigate the pricing performance of this approach over short and long time horizons by calibrating theoretical option prices under the Asymmetric GARCH model on S&P 500 market option prices. A new simplified scheme for delta hedging is proposed.

A GARCH Option Pricing Model in Incomplete Markets∗

We propose a new method for pricing options based on GARCH models with filtered historical innovations. In an incomplete market framework we allow for different distributions of the historical and the pricing return dynamics enhancing the model flexibility to fit market option prices. An extensive empirical analysis based on S&P 500 index options shows that our model outperforms other competing...

Valuing Real Options in Incomplete Markets

In this paper, we develop a framework for valuing real options and portfolios of real options in incomplete markets and show that it is a consistent generalization of contingent claims analysis, which is conventionally used for real option valuation in complete markets. The development of a framework for incomplete markets is motivated by the difficulty to construct replicating portfolios in pr...

A comparison of GARCH models for VaR estimation

In this paper the value at risk (VaR) forecasts are compared using three different GARCH models; ARCH(1), GARCH(1,1) and EGARCH(1,1). The implemented method is a one-day ahead out of sample forecast of the VaR. The forecasts are evaluated using the Kupiec test with a five percent significance level. The focus is on three different markets; commodities, equities and exchange rates. The goal of t...

Beyond Black-Scholes Option Theory

This article presents a new option pricing principle that is more useful than the no-arbitrage principle, especially for incomplete markets. The focus here is on ideas behind mathematics— why the new theory is warranted, and how common sense dictates its construction. I. Complete and Incomplete Markets The real financial world is too complicated for anyone to understand it completely. Thus a si...
