Towards Real-Time Risk Management on FPGA cards. Evaluation of Risk Sensitivities for the Black-Scholes, Heston and LIBOR Market Model using Maxeler technology, by Grzegorz Kozikowski, UoM

The financial models as Black-Scholes, Heston and LIBOR market model are widely used to price interest rate derivatives and option prices. Of particular interest are the risk sensitivities measured as first-order derivatives of these models rates with respect to all market model parameters. These numerical values known as the Greeks are interpreted and used by traders to neutralize the financial risk and hedge their investment portfolios against price fluctuations on the market. This work investigates a parallel approach to the Greeks' calculation for Black-Scholes, Heston and LIBOR market model. They are evaluated through a single Monte-Carlo simulation by the Adjoint method. The Monte-Carlo implementation is supported by FPGA card (Maxeler framework) and compared to a sequential version executed on Intel Sandybridge machine. The combination of the Adjoint and FPGA has improved performance by three orders of magnitude and contributes to better accuracy if compared to pathwise, finite difference or likelihood methods. The work present energy efficiency comparison of FPGA against CPUs.
