Jornal Do Brasilia - Seoul hits fresh record on mixed day for stock markets

Asian tech firms have enjoyed a blockbuster start to the year as investors reassess their AI bets, with attention 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 artificial intelligence and when that will see a return, while a slew of new tools has raised fears the technology will disrupt other businesses.

Still, Seoul climbed more than three percent to a fresh peak Thursday, a day after breaking 6,000 points for the first time, led again by a 7.1 percent surge in chipmaker Samsung and an 8.2 percent rally in rival SK hynix. The Kospi index is now up nearly 50 percent already this year.

Tokyo hit a new record, too, while Sydney, Wellington, Manila, Bangkok and Jakarta also enjoyed buying. Hong Kong, Singapore and Mumbai edged down, with Shanghai and Taipei flat.

London opened in the red with Frankfurt while Paris edged up.

While the mood remains upbeat, sentiment was tempered by disappointment over Nvidia's earnings, despite posting record revenue of $68.1 billion in October-December, thanks to insatiable demand for its AI chips.

It also forecast first-quarter revenue of between $76.4 billion and $79.6 billion, far above estimates of $72.8 billion.

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, with analysts saying expectations had become almost impossible to meet.

"There was a time when beating the number was enough. Now you have to beat the whisper, crush the dream, and torch the most optimistic sell-side spreadsheet in Silicon Valley just to keep the tape happy," wrote SPI Asset Management's Stephen Innes.

"On paper, this was another thunderclap quarter. And yet the stock dipped. The market is no longer pricing growth. It is pricing perpetuity."

And Charu Chanana at Saxo said: "We've moved from Phase One, where (capital expenditure) automatically meant upside for the entire ecosystem, to Phase Two, where investors want proof of monetisation and spending discipline.

"The key question is no longer 'who can spend the most', but 'who can turn that spend into durable profits'.

"That's why AI volatility can continue even after a big Nvidia beat."

Futures in all three main indexes on Wall Street were in the red, after they had enjoyed a strong run-up Wednesday.

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