Wall Street kicked off September with sharp losses on Tuesday, as a federal court’s ruling against most of President Donald Trump’s sweeping tariffs sent shockwaves through investors. The S&P 500 and Nasdaq each dropped over 1 percent, raising fresh questions about trade policies and economic fallout. What does this mean for your portfolio, and could more volatility lie ahead?
Court Ruling Shakes Up Trade Landscape
A divided U.S. appeals court ruled on Friday that most of Trump’s global tariffs are illegal. This decision has left markets reeling, with the tariffs allowed to stay in place only until October 14 while the administration considers an appeal to the Supreme Court.
Investors fear this could strip away key revenue streams and strain ties with trading partners. The ruling comes at a tense time, just as September, historically the weakest month for U.S. stocks, gets underway. Data from decades of market history shows September often brings average declines, and this year feels no different.
The CBOE Volatility Index, known as Wall Street’s fear gauge, jumped to its highest level in over four weeks, closing at 18.1. That spike signals growing unease among traders.
Oliver Pursche, a senior vice president at Wealthspire Advisors, pointed out the dual hit. He noted that markets are grappling with lost tariff income and damaged international relationships.
Major Indexes Feel the Heat
The Dow Jones Industrial Average fell 389.54 points, or 0.86 percent, to close at 45,155.34. The S&P 500 dropped 68.57 points, or 1.06 percent, ending at 6,391.69. Meanwhile, the Nasdaq Composite slid 274.17 points, or 1.28 percent, to 21,181.24.
Real estate and technology sectors led the S&P 500’s declines, hit hard by rising uncertainty. Bond yields also climbed, adding pressure as investors braced for potential shifts in Federal Reserve policy.
Traders are now eyeing the August nonfarm payrolls report, set for release on Friday. Markets see a 91.2 percent chance of a 25-basis-point rate cut at the Fed’s meeting later this month, based on CME Group’s FedWatch tool.
On the Nasdaq, declining stocks outnumbered advancers by a 2.39-to-1 ratio, with 1,334 risers against 3,194 fallers. The NYSE showed an even steeper imbalance, with decliners outpacing advancers 3.1 to 1.
Company Winners and Losers Emerge
Amid the broader sell-off, some stocks bucked the trend. PepsiCo shares rose 1.6 percent after activist investor Elliott Management revealed a $4 billion stake and launched a campaign for changes.
In contrast, Kraft Heinz plunged 7.4 percent on news it would split into two separate publicly traded companies. This move aims to streamline operations but spooked investors amid the market turmoil.
Other sectors felt the ripple effects. Retailers and manufacturers tied to global supply chains could see relief if tariffs ease, potentially lowering costs for imported goods. But “America First” industries might lose their protective edge, leading to tougher competition.
Here’s a quick look at key market movers:
- PepsiCo: Up 1.6 percent on activist push for value.
- Kraft Heinz: Down 7.4 percent amid split announcement.
- Technology sector: Led S&P declines, down sharply on growth worries.
- Real estate: Hit hardest, reflecting sensitivity to rates and trade.
Broader Economic Ripples and Historical Context
This tariff drama unfolds against a backdrop of ongoing economic concerns. Trump’s policies have already boosted U.S. tariff revenue, with July 2025 figures hitting a record $29.6 billion, up 300 percent from prior levels. At that pace, annual collections could exceed $350 billion, rivaling corporate income tax hauls.
Yet, critics warn of downsides. Studies from firms like JPMorgan estimate new tariffs could lift core inflation by 1 to 1.5 percent this year. Morgan Stanley predicts delayed Fed rate cuts, possibly until March 2026.
Historical data adds caution. September has averaged negative returns for the S&P 500 over the past century, according to research from the Stock Trader’s Almanac, last updated in 2024. This year’s setup, with tariff uncertainty and upcoming jobs data, amplifies the risks.
Investors like you might feel this in everyday ways. Higher inflation from sustained tariffs could mean pricier groceries and goods, while market dips affect retirement savings.
| Index | Closing Value | Point Change | Percent Change |
|---|---|---|---|
| Dow Jones | 45,155.34 | -389.54 | -0.86% |
| S&P 500 | 6,391.69 | -68.57 | -1.06% |
| Nasdaq | 21,181.24 | -274.17 | -1.28% |
Looking Ahead to Fed Moves and Appeals
The Trump administration has until mid-October to appeal, which could drag this saga into the Supreme Court. If the ruling stands, it might reshape U.S. trade strategy, easing some inflationary pressures but sparking retaliation from partners like China and the EU.
Bank of America analysts project tariffs could slash 2025 S&P 500 earnings by about 10 percent, with U.S.-China tensions alone accounting for 9 percent of that hit. They lowered their S&P target to 5,600, assuming flat growth.
Fed watchers are on edge too. With bond yields rising the 30-year Treasury neared 5 percent for the first time since July investors worry about borrowing costs climbing.
This uncertainty ties into bigger questions about Fed independence, especially amid leadership debates.
In all, Tuesday’s action highlights how quickly policy shifts can sway markets. As one trader put it, it’s too soon to panic, but vigilance is key heading into a volatile season.
As Wall Street navigates this turbulent start to September, the Trump tariffs ruling serves as a stark reminder of how trade policies can jolt economies and portfolios alike. It underscores the delicate balance between protectionism and global ties, leaving many to wonder if relief or more chaos awaits.
