Seoul Gazette - Tech firms lead Asian stock rout as AI bubble fears linger

A blockbuster earnings report from chip bellwether Nvidia on Wednesday seemed to settle nerves that vast investments in the artificial intelligence sector may have been overdone.

But the euphoria was short-lived as warnings grow that the tech-led rally across equities -- which has seen several markets hit records and companies clock eye-watering capitalisations -- may have run its course, and a correction could be in hand.

In unveiling Nvidia's forecast-topping report, boss Jensen Huang dismissed fears of a bubble that has caused global equities to wobble.

"From our vantage point, we see something very different," he said.

After his firm sparked an Asia rally on Thursday, Wall Street began on a strong note, but later went into sharp reverse, with selling compounded by worries over the US labour market.

Data showed that while more jobs were created in September, the unemployment rate crept higher.

The reading did little to alter investors' belief that the Federal Reserve will stand pat on borrowing costs when it meets next month, with officials more focused on stubbornly high inflation.

Expectations had already been dampened by recent comments from decision-makers, including boss Jerome Powell, that were on the hawkish side.

Tracking New York, Asian markets were a sea of red, with tech giants leading the way.

Seoul-listed Samsung Electronics sank nearly five percent and rival SK hynix more than nine percent -- the firms are two of the world's leading memory chip makers.

Another chip titan, TSMC, tanked nearly four percent in Taiwan, while Japan's SoftBank plunged more than 10 percent in Tokyo.

That led broader markets lower.

Tokyo, Hong Kong, Seoul, Sydney and Taipei were all down between 1.6 percent and 3.2 percent. There were also losses in Shanghai, Singapore and Wellington.

The rush from risk assets also saw bitcoin fall below the $93,000 mark for the first time since April, extending a sell-off suffered since its record high above $126,200 touched just last month.

"The price action across markets has been prolific, and we've seen some truly impressive reversals in risk assets," said Chris Weston at Pepperstone.

"Sentiment in so many markets remains highly challenged, and we've seen new evidence that managers are dumping their 2025 winners -- raising expectations that the path of least resistance is for risk to trade lower in the near-term.

"The market seems far more sensitive and ready to de-risk on emerging news, almost seeking reasons to take positioning down when that news could easily be seen as a positive in a more bullish set-up."

Eyes are also on Tokyo, where there is talk that Japanese Prime Minister Sanae Takaichi will unveil a huge stimulus package worth around $130 billion to boost the stuttering economy.

But government bond yields have soared in recent days on warnings that the spending will likely need even more borrowing, fanning concerns about the country's fiscal state and putting huge pressure on the yen.

The Japanese currency has fallen this week to its lowest level against the dollar since January, though it got a little support from data showing core inflation ticked up last month, giving the Bank of Japan some room to hike interest rates.
