[U.S. Supreme Court to Rule on Legality of Trump Tariffs] The U.S. Supreme Court is set to rule on the legality of the comprehensive tariffs introduced by President Trump in April. The S&P 500 Index has rebounded 39% from its low point that month, closing at a record high on Thursday. The court held its final public hearing of the year on Wednesday, with the next session scheduled for January 9 next year. Wells Fargo's chief equity strategist estimated in October that if the tariffs are ruled invalid, the earnings before interest and taxes (EBIT) of S&P 500 constituent companies will grow by 2.4% by 2026 compared to this year.
