Japanese chipmaker Kioxia has lost half its value since hitting a record high last month and becoming the country's biggest firm by market capitalisation

Tokyo and Taipei led losses on a glum day for Asian markets Friday, with tech firms once again in the crosshairs as investors cash in following this year's breathtaking rally.

The AI boom has sent technology valuations soaring to record levels as traders looked to get a slice of the next big thing while firms splashed out enormous amounts of money in investment.

But questions have been raised in recent months about whether valuations have gone too far and when companies will actually see any returns.

Worries about the AI trade have hammered the value of chip firms, with the Philadelphia Semiconductor Index losing about 19 percent from a June peak, according to Bloomberg.

Asian markets have been hammered, with Seoul's Kospi bearing the brunt of the selling, having more than doubled in the first six months of the year before losing about a third of its value since hitting a record in June.

But with South Korea enjoying a holiday on Friday, Tokyo and Taipei -- which are also heavily weighted toward tech -- were at the forefront of the selling.

Japan's Nikkei sank as much as four percent with Advantest and tech investment titan SoftBank losing around nine percent.

Chipmaker Kioxia collapsed 16 percent, meaning it has lost more than half its value since hitting a record high and becoming the country's biggest firm by market capitalisation last month.

Taiwan's Taiex also shed four percent as chipmaker TSMC retreated more than three percent a day after announcing record second-quarter profit and that it would invest a further $100 billion in the US state of Arizona.

There were also losses in Hong Kong, Shanghai, Singapore and Sydney.

"It looks like the rally in artificial intelligence-related stocks appears to be losing some momentum after months of almost uninterrupted gains," said Fawad Razaqzada, a market analyst at Forex.com.

"Given the pace of the prior advance, some consolidation was always likely. But there are some investors who are increasingly questioning whether the enormous sums being committed to AI infrastructure can generate sufficient returns within a reasonable timeframe."

However, he added that the selling "could simply reflect a period of portfolio rotation".

"Some investors may prefer to lock in profits from richly valued semiconductor names and reallocate capital towards sectors offering more attractive valuations and steadier earnings visibility," he wrote.

The dour mood in Asia followed losses in New York, where sharp falls in Nvidia and Amazon helped drag the Nasdaq down more than one percent.

And Netflix plunged more than nine percent in after-hours trade as it warned of a second quarter of slowing sales growth.

"The AI trade keeps learning the same lesson the hard way: when a stock goes vertical, it does not need bad news to come down. It just needs buyers to stop paying any price," said SPI Asset Management's Stephen Innes.

Oil prices jumped one percent as the US and Iran continued to exchange strikes in a flare-up that has seen traffic through the key Strait of Hormuz fall back to a trickle.

The renewed hostilities have fanned fears of a return to war that could send crude prices back higher, putting fresh pressure on inflation and eventually forcing central banks to hike interest rates.
