Quantum computing for multidimensional option pricing: End-to-end pipeline

Julien Hok, Álvaro Leitao

This work introduces an end-to-end framework for multi-asset option pricing that combines market-consistent risk-neutral density recovery with quantum-accelerated numerical integra…

The importance of being scrambled: supercharged Quasi Monte Carlo

J. Hok, S. Kucherenko

In many financial applications Quasi Monte Carlo (QMC) based on Sobol low-discrepancy sequences (LDS) outperforms Monte Carlo showing faster and more stable convergence. However, u…

Speeding up the Euler scheme for killed diffusions

Umut Çetin, Julien Hok

Let be a linear diffusion taking values in and consider the standard Euler scheme to compute an approximation to for a given f…

Pricing and Risk Analysis in Hyperbolic Local Volatility Model with Quasi Monte Carlo

Julien Hok, Sergei Kucherenko

Local volatility models usually capture the surface of implied volatilities more accurately than other approaches, such as stochastic volatility models. We present the results of a…

Calibration of Local Volatility Model with Stochastic Interest Rates by Efficient Numerical PDE Method

Julien Hok, Shih-Hau Tan

Long maturity options or a wide class of hybrid products are evaluated using a local volatility type modelling for the asset price S(t) with a stochastic interest rate r(t). The ca…

Expansion formulas for European quanto options in a local volatility FX-LIBOR model

Julien Hok, Philip Ngare, Antonis Papapantoleon

We develop an expansion approach for the pricing of European quanto options written on LIBOR rates (of a foreign currency). We derive the dynamics of the system of foreign LIBOR ra…

Option pricing with Legendre polynomials

Julien Hok, Tat Lung Chan

Here we develop an option pricing method based on Legendre series expansion of the density function. The key insight, relying on the close relation of the characteristic function w…
