Zürcher Nachrichten - Asian markets tumble as tech bubble fears grow

Global markets have soared this year as an eye-watering flood of cash piled into companies linked to artificial intelligence, including US titans Nvidia, Amazon and Apple as well as Asian firms Samsung and Alibaba.

But despite strong earnings releases in recent quarters, traders have started questioning the wisdom of chasing ever-higher prices, with cash mostly funnelled into a handful of big-name companies.

The gains have also been helped by an easing of US trade tensions and expectations that the Federal Reserve will continue to cut interest rates into the new year.

But last week's warning from the US central bank that another reduction in December was not a foregone conclusion jolted sentiment.

After an uncertain start to the week Monday, Wall Street tumbled on Tuesday, with the tech-rich Nasdaq down more than two percent and the S&P 500 off more than one percent.

US software firm Palantir slumped 8.0 percent despite reporting a 63 percent surge in revenues and profits.

Asia took up the baton in the morning, with Seoul and Tokyo the hardest hit, having just hit record highs.

Seoul tanked six percent at one point, as chip giants Samsung and SK hynix each lost around seven percent.

"I view today's decline as a correction to cool off an overheated market -- a phase of adjustment," Chung Hae-chang, analyst at Daishin Securities, told AFP.

"The recent rally was extremely steep, so this is the counterbalance."

He also warned Seoul's Kospi index could decline five percent further and that "SK hynix and Samsung may also see corrections proportional to their earlier gains".

Tokyo dived more than four percent as tech investment giant SoftBank shed 14 percent and Sony more than two percent.

Nintendo, however, briefly jumped more than 10 percent a day after the gaming firm hiked forecasts for its Switch 2 console and annual profits.

- 'Sea of red' -

Taipei was off more than two percent as market heavyweight and chip-maker TSMC gave up three percent.

There were also big losses in Hong Kong, Shanghai, Singapore, Sydney, Wellington, Manila and Jakarta.

"It's a sea of red across broad markets, and one that offers a gloomy and damp portrayal of risk," said Chris Weston at Pepperstone.

"In the lead-up to the session, traders had been rotating out of the lower-quality end of the market and into the higher-quality plays, and this dynamic resulted in poor breadth within the US equity indices."

He said that dynamic had changed and traders were "cutting back on their winners and locking in performance, with the Magnificent Seven (leading tech stocks) basket and AI plays driving equity risk lower."

And Mike Gitlin, president and chief executive officer of Capital Group, said that while earnings are strong "what's challenging are valuations", according to Bloomberg.

His comments came at a financial summit organized by the Hong Kong Monetary Authority on Tuesday, where other business leaders including Morgan Stanley boss Ted Pick and Goldman Sachs' David Solomon warned of a big correction.

Meanwhile, Saxo Markets' Charu Chanana said two questions were echoing across portfolios.

"Those who've ridden the rally from early 2023 are sitting on substantial gains and wondering if it's time to lock in profits (and) those still on the sidelines are feeling the pull of (fear of missing out, questioning if they've missed the best entry point.

"Both are fair concerns. The AI boom has pushed the 'Magnificent' names to new highs, but under the surface, their stories have begun to diverge between companies monetising AI today and those still investing for tomorrow."

The uncertainty across markets was also felt in the crypto universe, where bitcoin briefly fell below $100,000 for the first time since June, a month after topping out at a record high above $126,000.
