The three major U.S. stock indexes in New York closed higher.
On the 20th (local time) at the New York Stock Exchange (NYSE), the Dow Jones Industrial Average rose 230.81 points, or 0.47%, from the previous session to close at 49,625.97. The Standard & Poor's (S&P) 500 index added 47.62 points, or 0.69%, to 6,909.51, and the Nasdaq composite jumped 203.34 points, or 0.90%, to finish at 22,886.07.
That day, the U.S. Supreme Court ruled that U.S. President Donald Trump's reciprocal tariff policy was unlawful, but the market rose instead. CNBC said uncertainty eased because the outlook suggested that corporations' expense pressures from the tariffs would abate and concerns about inflation, a chronic problem for the U.S. economy, would also subside.
But factors that can still shake the market remain. After the Supreme Court ruling, Trump said at a news conference that he would impose an additional 10% tariff on exports to the United States and proceed with other tariff measures.
The Associated Press said, "After the release of a disappointing report showing a slowdown in the U.S. economy, the indexes maintained composure, seesawing slightly up and down until the Supreme Court decision."
That day, the U.S. Department of Commerce said the U.S. gross domestic product (GDP) growth rate in the fourth quarter of last year was 1.4% (quarter-over-quarter annualized, advance estimate). That was well below the 2.5% forecast compiled by Dow Jones. The fourth-quarter economy was hit by the fallout from the 43-day U.S. federal government shutdown (temporary halt of operations) that began on Oct. 1 last year.
