As a natural extension to León and Vivas (2010) and León and Reveiz (2010) this paper briefly describes the Cholesky method for simulating Geometric Brownian Motion processes with long term dependence, also referred as Fractional Geometric Brownian Motion (FBM). Results show that this method...

Whilst emphasis has been given to short-term dependence of financial returns, long-term dependence remains overlooked. Despite the fact than financial literature provides evidence of long-term memory existence, serial-independence assumption prevails. This document's long-term dependence...
