The Merton Jump-Diffusion Model
Merton (1976) [1] jump-diffusion model is an extension to the Geometric Brownian Motion model, with the underlying asset exhibit jumps in addition to have continuous diffusion paths. The asset price evolves as
dS t =μS t dt + σS t dW t + (η−1)dq
where μ is the drift rate, σ the volatility of S and dW t the increment of a Wiener process. The independent Poisson process dq has a value of 1 with probability λdt and 0 otherwise.
The following is a ThetaML implementation of the Merton Jump-Diffusion Model.
