Model stohastičke volatilnosti (Heston)

Model stohastičke volatilnosti je okvir za procenu cena opcija i upravljanje rizikom u kontinuiranom vremenu, u kojem volatilnost prati sopstveni slučajni proces umesto da ostane konstantna. Hestonov model, koji je uveo Steven Heston 1993. godine, daje kvadratnom korenu varijanse dinamiku povratka ka srednjoj vrednosti (CIR) i omogućava zatvorenu formu cene opcije; on je pandan GARCH modela u kontinuiranom vremenu.
