Kou Model

Algorithm

The Kou Model, introduced by Steven Kou in 2002, represents a stochastic process for modeling asset prices, extending the Merton jump-diffusion model by incorporating a double exponential jump size distribution. This allows for both positive and negative jumps, capturing asymmetry often observed in financial markets, particularly relevant in cryptocurrency price action where sudden shifts are common. Its application in derivatives pricing provides a more nuanced valuation compared to models assuming continuous price paths, offering a framework for options on volatile assets. The model’s parameters—drift, volatility, and jump parameters—are typically calibrated using observed market data, enabling risk managers to assess potential downside exposure.
