Resumen de Do common volatility models capture cyclical behaviour in volatility?

A.E. Clements, Jérôme Collet

• This article examines whether commonly used models of volatility can capture the cyclical behaviour of equity market volatility. The ability of a number of models to account for the dynamics governing periods of increasing and decreasing volatility will be examined. In summary, the commonly used models considered here do not adequately capture the average duration of cycles or the duration dependence in equity volatility.
