초록: We introduce a new stochastic volatility model of Volterra–Heston type and show that the characteristic function of its risk-neutral log-price distribution can be found in closed form. This allows to use Fourier transform methods for very fast computation of model option prices. In an extensive numerical calibration study on real market data, we show that our new model considerably outperforms, both in terms of accuracy and in terms of speed, the classic Heston, the rough Heston and the rough Bergomi model.
