This paper presents a new approach to modeling the dynamics of implied distributions. First, we obtain a parsimonious description of the dynamics of the S&P 500 implied cumulative distribution functions by applying principal components analysis. Subsequently, we develop new arbitrage-free Monte Carlo simulation methods that model the evolution of the whole distribution through time as a diffusion process. Our approach generalizes the conventional approaches of modeling only the first two moments as diffusion processes, and it has important implications for "smile-consistent" option pricing and for risk management. The out-of-sample performance within a Value-at-Risk framework is examined. (C) 2003 Elsevier B.V. All rights reserved.
