Wall Street closes higher on Nvidia results

US stocks have closed slightly higher as shares of Nvidia gained after its quarterly results, while investors digested a late-afternoon court ruling that reinstated the most sweeping of President Donald Trump's tariffs.

The appeals court ruling came a day after a trade court had ordered an immediate block on the tariffs.

Indexes ended well off their highs of the day. Salesforce shares fell even as the enterprise software provider raised its annual revenue and adjusted profit forecasts.

"Trump has already rolled back most of these tariffs anyway, so these court rulings are just headlines," said Adam Sarhan, chief executive of 50 Park Investments in New York.

Nvidia gained after the company late on Wednesday reported upbeat sales results, driven by customers stockpiling AI chips ahead of US export restrictions on China.

The company, however, warned the new curbs are expected to cut $US8 billion from its current-quarter sales.

Optimism about corporate earnings and Nvidia in particular is providing some support, said Oliver Pursche, senior vice president, adviser for Wealthspire Advisors in Westport, Connecticut.

But he added, "As an investor, I don't think there's an impetus to do anything or change anything, and that's what the market is reflecting."

According to preliminary data, the S&P 500 gained 23.53 points, or 0.40 per cent, to end at 5,912.08 points, while the Nasdaq Composite gained 74.77 points, or 0.39 per cent, to 19,175.87. The Dow Jones Industrial Average rose 118.97 points, or 0.28 per cent, to 42,217.67.

Boeing rose after CEO Kelly Ortberg said the planemaker aims to increase production of its best-selling 737 MAX jets to 42 aircraft per month in the next few months and boost output to 47 a month in early 2026.

A second reading from the Commerce Department showed gross domestic product contracted 0.2 per cent in the first quarter. Economists polled by Reuters had forecast a 0.3 per cent contraction.

In other earnings, Best Buy shares fell after the electronics retailer lowered its annual comparable sales and profit forecasts amid concerns that US tariffs would weigh on consumer demand for big-ticket items.
