Lire la dominance comme un indicateur de r\u00e9gime, surveiller la largeur du march\u00e9 via l&rsquo;indice alt, v\u00e9rifier la profondeur r\u00e9elle avant de s&rsquo;exposer sur des segments \u00e9troits. Le cycle actuel ne r\u00e9compense pas le \u00ab tout-terrain \u00bb, il r\u00e9compense <strong>la pr\u00e9cision et la gestion<\/strong> du risque.<\/p>\n<p>Si la dominance se <strong>calme<\/strong> et que l&rsquo;indice repasse franchement au-dessus de 75, le march\u00e9 donnera un signal plus clair.
