Le 3 novembre 2026, les \u00e9lecteurs choisiront les 435 membres votants de la Chambre des repr\u00e9sentants et environ un tiers du S\u00e9nat. Le r\u00e9sultat dira si le pr\u00e9sident Donald Trump conserve un Congr\u00e8s favorable ou doit faire face \u00e0 plus d\u2019opposition pour faire voter ses textes. Historiquement, le S&amp;P 500 a eu tendance \u00e0 moins bien progresser lors des ann\u00e9es de mi-mandat, avant de mieux performer l\u2019ann\u00e9e suivante, dite pr\u00e9-\u00e9lectorale.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.vtmarkets.com\/wp-content\/uploads\/2026\/10\/img_6acc44f2814eb.png\" alt=\"\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Le S&amp;P 500 a d\u00e9j\u00e0 rebondi depuis son point bas de mars 2026 et a atteint des records en octobre. Le repli (correction, baisse notable apr\u00e8s une hausse) observ\u00e9 plus t\u00f4t cette ann\u00e9e a aussi \u00e9t\u00e9 moins marqu\u00e9 que la moyenne historique des ann\u00e9es de mi-mandat. Deux sc\u00e9narios se dessinent. Si les r\u00e9sultats d\u2019entreprises et l\u2019inflation se stabilisent, la hausse pourrait se prolonger en 2027. Si l\u2019inflation reste \u00e9lev\u00e9e ou si les rendements des obligations d\u2019\u00c9tat continuent de monter, la pression pourrait revenir sur les valorisations avant l\u2019\u00e9lection. Au final, la croissance des profits et la politique mon\u00e9taire (d\u00e9cisions de taux de la banque centrale) seront d\u00e9terminantes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Le contr\u00f4le du Congr\u00e8s peut-il changer la perspective pour les actions ?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le r\u00e9sultat du scrutin peut modifier les attentes sur la politique budg\u00e9taire am\u00e9ricaine, notamment la fiscalit\u00e9, les d\u00e9penses publiques et la r\u00e9gulation. Une majorit\u00e9 r\u00e9publicaine dans les deux chambres donnerait plus de marge \u00e0 l\u2019administration Trump pour appliquer son programme. Une majorit\u00e9 d\u00e9mocrate dans au moins une chambre pourrait freiner l\u2019agenda et accro\u00eetre les tensions autour du budget.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.vtmarkets.com\/wp-content\/uploads\/2026\/10\/img_6acc44f364e58.png\" alt=\"\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Selon une \u00e9tude de RBC Wealth Management couvrant 1953 \u00e0 2025, les performances de march\u00e9 varient selon les configurations entre la pr\u00e9sidence et le Congr\u00e8s.

Les profits des entreprises sont d\u00e9terminants : une hausse durable des cours n\u00e9cessite une progression suffisante des r\u00e9sultats pour justifier les valorisations, surtout si les rendements des obligations d\u2019\u00c9tat restent \u00e9lev\u00e9s.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si l\u2019inflation persiste, la Fed peut maintenir des co\u00fbts d\u2019emprunt \u00e9lev\u00e9s plus longtemps, m\u00eame si la politique budg\u00e9taire soutient davantage l\u2019activit\u00e9.

class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Le S&amp;P 500 aborde la semaine du 12 octobre avec une dynamique favorable, mais les chiffres d\u2019inflation et l\u2019approche des \u00e9lections de mi-mandat peuvent provoquer un mouvement plus net. Le CPI de mercredi testera les anticipations d\u2019un nouveau rel\u00e8vement des taux de la Fed, tandis que le PPI et les ventes au d\u00e9tail de jeudi pourront confirmer ou contredire la premi\u00e8re r\u00e9action. Les op\u00e9rateurs surveilleront si l\u2019USDX s\u2019approche de <strong>102,55<\/strong>, si l\u2019or se rapproche de <strong>4 280 $<\/strong> et si le S&amp;P 500 reste au-dessus de ses r\u00e9cents sommets.<\/p>\n\n\n\n<details class=\"wp-block-details is-layout-flow wp-block-details-is-layout-flow\"><summary><strong>Questions fr\u00e9quentes<\/strong><\/summary>\n<h3 class=\"wp-block-heading\">Comment les \u00e9lections am\u00e9ricaines de mi-mandat peuvent-elles affecter le S&amp;P 500 en 2026 ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les \u00e9lections de mi-mandat du 3 novembre 2026 peuvent influencer le sentiment de march\u00e9 via la politique budg\u00e9taire, les imp\u00f4ts et les d\u00e9penses publiques. Historiquement, ces ann\u00e9es ont souvent \u00e9t\u00e9 plus volatiles (variations de prix plus fortes), tandis que l\u2019ann\u00e9e suivante a souvent \u00e9t\u00e9 meilleure pour le S&amp;P 500. Mais l\u2019inflation, les taux d\u2019int\u00e9r\u00eat et les r\u00e9sultats des entreprises restent d\u00e9terminants.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Quelle est la pr\u00e9vision de CPI am\u00e9ricain pour octobre 2026 ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Les pr\u00e9visions portent l\u2019inflation CPI de septembre \u00e0 3,6% sur un an, contre 3,4% auparavant. La publication est pr\u00e9vue le 14 octobre 2026. Une inflation sup\u00e9rieure aux attentes peut soutenir le dollar et les rendements des obligations d\u2019\u00c9tat, tandis qu\u2019une inflation plus faible peut soutenir l\u2019or et les actions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Le S&amp;P 500 va-t-il continuer de monter en octobre 2026 ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Le S&amp;P 500 est entr\u00e9 en octobre avec une dynamique positive, en hausse d\u2019environ 14,1% depuis le d\u00e9but de l\u2019ann\u00e9e au 9 octobre. La poursuite de la hausse d\u00e9pend notamment des r\u00e9sultats d\u2019entreprises, des donn\u00e9es d\u2019inflation et des attentes de politique mon\u00e9taire (taux de la Fed). Les op\u00e9rateurs surveilleront si l\u2019indice tient de nouveaux sommets interm\u00e9diaires ou s\u2019il fait face \u00e0 une nouvelle phase de ventes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Quelles perspectives pour l\u2019or cette semaine ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L\u2019or s\u2019est repris depuis la zone autour de 4 080 $, et 4 280 $ appara\u00eet comme le prochain niveau \u00e0 surveiller. En cas de repli, une zone autour de 4 055 $ peut attirer des acheteurs. La direction de l\u2019or d\u00e9pendra aussi des chiffres d\u2019inflation, des rendements obligataires et du dollar.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Comment le CPI am\u00e9ricain peut-il affecter l\u2019EURUSD et le dollar ?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Un CPI sup\u00e9rieur aux attentes peut renforcer les anticipations de nouvelles hausses de taux de la Fed, ce qui soutiendrait l\u2019USDX (indice du dollar) et p\u00e8serait sur l\u2019EURUSD. Une inflation plus faible peut produire l\u2019effet inverse. Une r\u00e9sistance sur l\u2019USDX se situe vers 102,55, tandis que sur l\u2019EURUSD, les op\u00e9rateurs surveillent un support vers 1,1110 et une r\u00e9sistance vers 1,1350.<\/p>\n<\/details>\n\n\n\n\n<p class=\"wp-block-paragraph\"><b>Commencez \u00e0 trader d\u00e8s maintenant \u2014 cliquez <a href=\"https:\/\/www.vtmarkets.com\/fr-eu\/trade-now\/\">ici<\/a> pour cr\u00e9er votre compte r\u00e9el VT Markets.<\/b>\n\n<\/p>","protected":false},"excerpt":{"rendered":"<p>Wall Street aborde un carrefour explosif : mi-mandat le 3 novembre, CPI attendu \u00e0 3,6% le 14 octobre et saison des r\u00e9sultats.
