Equity futures are noticeably lower across the board, with tariff news acting as the catalyst.<\/p>\n\n\n\n<p>Currently, the S&amp;P 500 futures are down 77 points and are trading 1.2% below fair value, the Nasdaq 100 futures are down 366 points and are trading 1.6% below fair value, and the Dow Jones Industrial Average futures are down 455 points and are trading 1.0% below fair value.<\/p>\n\n\n\n<p>This negative disposition follows a U.S. Court of Appeals ruling late Friday that most of the global tariffs announced by President Trump are illegal, since &#8220;tariffs are a core Congressional power.&#8221; That ruling won&#8217;t go into effect until October 14, however, meaning the tariffs are still in force today, as the court is expecting the administration to appeal its ruling to the Supreme Court.<\/p>\n\n\n\n<p>The stock market doesn&#8217;t look too thrilled by this news, which introduces a new layer of uncertainty around an already uncertain situation. It isn&#8217;t thrilled either by the sight of market rates going up in the wake of the ruling. Remember, the tariff revenue has been advertised as a payment method for the One Big Beautiful Bill Act that keeps the deficit from getting much worse.<\/p>\n\n\n\n<p>The 2-yr note yield is up five basis points to 3.67%, and the 10-yr note yield is up seven basis points to 4.30%. To be fair, the yields on both securities remain well below where they started the year, but sometimes the direction and pace of travel are more important to the market than the level.<\/p>\n\n\n\n<p>In any case, it is another excuse for market participants to do some selling. The other excuse one might hear is the seasonal factor, or &#8220;seasonality.&#8221; The month of September has been the worst month of the year for the stock market since 1928, with an average decline of nearly 1.2%.<\/p>\n\n\n\n<p>There is no telling at this point what this September will bring, yet the market will be starting in a hole.<\/p>\n\n\n\n<p>Weakness in the mega-cap stocks is doing most of the digging for the equity futures; however, the scope of this morning&#8217;s weakness suggests the early selling is going to be broad-based and rooted in a &#8220;macro trade.&#8221; There isn&#8217;t any company-specific news that is driving sentiment.<\/p>\n\n\n\n<p>The macro picture will come into further focus after the opening bell. Today&#8217;s economic lineup includes the final S&amp;P Global U.S. Manufacturing PMI reading for August (prior 53.3) at 9:45 a.m. ET, the July Construction Spending Report (Briefing.com consensus: 0.2%; prior -0.4%) at 10:00 a.m. ET, and the August ISM Manufacturing Index (Briefing.com consensus: 48.6%; prior 48.0%) at 10:00 a.m. ET.<\/p>\n\n\n\n<p>&#8212;<\/p>\n\n\n\n<p>Originally Posted September 2, 2025 &#8211; <a href=\"https:\/\/www.briefing.com\/page-one\">Market set to start September in a hole after tariff ruling<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Court ruling on tariffs triggers selling interest.
