Fourier Transform of Lookback Option Price

الملخص EN

The Fourier transform of the damped price of Lookback option under B-S model is presented.

Thus, the Lookback option across a range of strikes can be simultaneously priced via FFT algorithm.

FFT algorithm is more efficient than both Monte Carlo simulation method and the integral of the usual pricing formula.

In addition, by FFT algorithm, investors can easily capture the sensitivity of option prices when the strike prices vary as to make reasonable investment decisions.
