Secteur & Industrie Actions présentant la volatilité la plus élevée — Bourse américaine
La volatilité d'une action correspond à la fluctuation du cours sur une période donnée. Les actions les plus volatiles peuvent présenter des fluctuations de prix allant jusqu'à plusieurs centaines de pourcents pendant la journée. Sur les marchés développés, la volatilité tend à être beaucoup plus faible et ne dépasse pas 20-30%% pendant les périodes calmes. Les fluctuations de prix ne sont pas toujours évidentes lorsqu'on regarde les actions dont le prix est inférieur à 1 $. Vous pouvez voir les variations de prix en pourcentages pour détecter ces fluctuations.
