Les lettres grecques Comprendre la formation des prix
Les lettres grecques associées aux options jouent un rôle essentiel dans l’analyse des mouvements de prix des options. Des indicateurs comme le delta, le gamma, le vega et le theta permettent de comprendre comment différents facteurs — tels que le cours du sous-jacent, le temps restant jusqu’à l’échéance et la volatilité — influencent la prime de l’option.
Lors du trading d’options, les grecques des options peuvent aider à mieux comprendre l’évolution des prix dans différents contextes de marché. Par exemple, le delta indique la sensibilité du prix de l’option aux variations du cours du sous-jacent, tandis que le theta reflète l’impact de l’écoulement du temps sur la valeur de l’option.
Sur cette page, vous trouverez des articles expliquant le rôle de chacunes des grecques et illustrant leur influence sur le prix des options à l’aide d’exemples concrets.
