New York Stock Exchange Closes Higher Following US Supreme Court Tariff Ruling

Positive Momentum in Markets The New York Stock Exchange concluded the final trading day of the week on a high note after the US Supreme Court ruled that the "emergency" tariffs implemented by President Donald Trump were unlawful.
At the close, the Dow Jones Industrial Average rose by more than 200 points, gaining 0.47 percent to reach 49,625.97.
The S&P 500 index increased by 0.69 percent to 6,909.51, while the Nasdaq composite climbed 0.90 percent to 22,886.07.
Supreme Court Limits Executive Authority In a pivotal decision for the markets, the Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA), which served as the basis for the tariffs, does not grant the president the authority to impose customs duties.
The 6-3 ruling emphasized that the power to impose taxes and tariffs belongs exclusively to Congress.
Analysts suggest this decision could provide relief to companies burdened by tariff costs and potentially ease inflation concerns.
President Trump described the ruling as "extremely disappointing" and pointed toward alternative methods for implementing tariffs, such as Section 122 of the Trade Act of 1974.
Economic Data and Growth Figures In addition to the court ruling, investors closely monitored macroeconomic data.
The US economy grew by 1.4 percent in the fourth quarter of 2025, falling below expectations.
The annual growth rate for the year was recorded at 2.2 percent.
The economic slowdown was attributed to the 43-day government shutdown—the longest in the country's history—and a decline in consumer spending.
Regarding inflation, the core Personal Consumption Expenditures (PCE) price index, a key metric for the Federal Reserve, rose by 3 percent annually in December, exceeding expectations.
Other data showed the manufacturing PMI retreating to 51.2 in February, while the University of Michigan consumer sentiment index was revised to 56.6.
