O petróleo bruto é uma das forças importantes que impulsionam a economia mundial. As flutuações dos preços do petróleo têm efeitos significativos no crescimento económico e no bem-estar em todo o mundo. Como os efeitos da volatilidade do petróleo se alargam do nÃvel das empresas para os governos, tanto os decisores polÃticos como os investidores estão interessados em modelizar e prever os preços do petróleo bruto. Dada a escassez de investigação sobre a modelização (especialmente a modelização assimétrica) e a previsão da volatilidade do petróleo bruto, o objetivo deste artigo é contribuir para esta escassa literatura sobre energia. O presente trabalho avalia o desempenho de vários modelos do tipo GARCH com aplicação em três benchmarks de petróleo bruto. A análise deverá ser essencial para a tomada de decisões financeiras e para a gestão de risco de carteiras, nomeadamente no que respeita à s questões de valorização dos produtos petrolÃferos e dos instrumentos derivados de energia.
