Title
Abstract
In this talk, I will present a derivation of binomial and trinomial trees using the path integral formalism of quantitative finance, resulting in a novel formula for delta is found based on the likelihood ratio method. This formula yields extremely accurate results at virtually no extra computational cost. Further, when combined with automatic differentiation, this method overcomes a known issue in that gamma is not computable on trees. Finally, I will show some current research broadening this new formula for delta to other cases – including a new method to stable “bumped” deltas for Monte Carlo.
