| description | This thesis addresses evaluation of American-style Asian options within a jumpdiffusion
framework, an extension of the traditional Black-Scholes model to capture
real-world financial market behaviors better. The primary objective of this research is to
develop an evaluation framework for pricing American-style Asian options, where the
strike price is dependent on the average path of the underlying asset prices. To address
these challenges, this research develops a comprehensive pricing model, comparing the
well-established Black-Scholes model with the Merton jump-diffusion model. Through
this comparison, it is demonstrated that the Merton model offers a more accurate representation
of market behaviors such as price jumps and volatility clustering. A decision
rule for initial parameter estimation using maximum likelihood estimation (MLE) is
proposed, affirming the Merton model’s suitability for real-world stock price behavior.
Utilizing theories of conditioned expectations and martingales, the research addresses
the free boundary problem associated with optimal early exercise. The Monte Carlo
simulation method is adapted to accommodate the complexity of the early exercise
boundary in this study. Further, the study develops numerical methods for solving the
nonlinear partial differential equations (PDEs) and variational inequalities that arise
in the valuation process. A penalty method is employed to approximate the nonlinear
complementarity problem (NCP) resulting from discretizing the free boundary problem.
Overall, significant results highlight the differences in option valuation with and
without the incorporation of jumps. In scenarios where jumps are present, the model
reflects larger and more sudden price changes, leading to significantly different option
prices compared to models that assume smooth, continuous price movements. Without
jumps, the valuation follows more predictable patterns, but it fails to capture extreme
market behaviors, which can lead to pricing inaccuracies, especially in volatile markets.
Numerical experiments conducted via the modified Monte Carlo simulation and the
penalty method underscore each method’s strengths and limitations, showcasing their
potential applications in practical scenarios in option pricing. |
