Heraldo de Madrid - Stocks mixed as investors digest Nvidia earnings

Oil prices fell as Iran and the United States began a new round of indirect talks on the Islamic republic's nuclear programme, in a last-ditch bid to avert war.

The market response to Nvidia's earnings Wednesday was muted as initial excitement over its record quarterly revenue gave way to concerns that sky-high expectations for AI have become almost impossible to meet.

Shares in the firm -- which last year became the first to top $5 trillion in market capitalisation -- dipped in after-hours trade in New York Wednesday.

"It says a lot when a stock market darling beating revenue forecasts by billions of dollars can no longer muster a positive share price reaction," said Dan Coatsworth, head of markets at AJ Bell.

"The mood music is changing on Nvidia, and it represents a significant shift in investor sentiment," he added.

Nvidia shares fell two percent as trading got underway in New York on Thursday.

Trade Nation analyst David Morrison, noted that Nvidia's shares had risen ahead of the earnings announcement.

Moreover, the announcement "wasn't the 'stellar' results with which the market has become accustomed, and this has left many investors pondering: 'What next?'"

Wall Street opened mixed, with the Dow rising, the S&P 500 flat and the tech-heavy Nasdaq slipping.

- Stellantis, Rolls-Royce up -

Shares in multinational automaker Stellantis, which is behind brands such as Jeep and Fiat, climbed six percent as trading got underway in New York.

The company posted a net loss of 22.3 billion euros ($26.3 billion) for last year, but it was mostly due to write-downs of assets as the carmaker shifts away from EVs.

Major European indices advanced in afternoon trading on Thursday.

London was boosted by a six-percent rise in Rolls-Royce shares after the British engine-maker upgraded its guidance, announced a share buyback and posted soaring annual profits.

Paris's CAC 40 index crossed the 8,600 level for the first time and Frankfurt also rose.

In Asia, Tokyo hit a new record, while Hong Kong edged down and Shanghai was flat.

Asian tech firms have enjoyed a blockbuster start to the year as investors reassess their AI bets. Attention is turning to "upstream" firms such as chipmakers and away from Wall Street's "downstream" companies that run apps and software.

The shift has come amid growing concerns about the hundreds of billions of dollars pumped into AI and when that will see a return, while a slew of new tools has raised fears the technology will disrupt other businesses.

Seoul nevertheless climbed more than three percent to a fresh peak on Thursday, led again by surges in chipmaker Samsung and rival SK hynix. The Kospi index is now up nearly 50 percent already this year.

On currency markets the yen clawed back some losses against the dollar that came after it emerged that Japanese Prime Minister Sanae Takaichi had nominated two academics to the Bank of Japan board who are considered policy doves.

That came after earlier reports had said she had told the central bank's boss Kazuo Ueda of her concern about hiking interest rates further.
