Asian technology stocks plunged on Monday June 8, erasing weeks of gains as investors concluded that the artificial intelligence rally had run too far ahead of financial fundamentals. South Korea’s Kospi index triggered a 20-minute circuit breaker after tumbling 8.8 per cent in morning trade, closing down 8.3 per cent at 7,484.41 in its steepest daily decline since March 4. Memory chip manufacturers Samsung Electronics and SK Hynix sank 10.2 per cent and 7.7 per cent, respectively.

The selloff swept across the region. Japan’s Nikkei 225 closed 3.9 per cent lower, Hong Kong’s Hang Seng Tech Index fell 1.2 per cent, and Taiwan Semiconductor Manufacturing Company dropped approximately 2 per cent. The declines extended a global tech rout that began on Wall Street, where the Nasdaq Composite had fallen 0.97 per cent the previous session and the iShares Semiconductor ETF ended down 1 per cent.

Real-world impact for investors is immediate. Portfolios heavy in semiconductor and AI-related stocks faced sharp losses, with valuation multiples that had climbed to multi-year highs now under scrutiny. Traders reported mounting concern that companies have poured billions into AI infrastructure without demonstrating proportional revenue growth or clear paths to profitability.

South Korea Faces Steepest Tech Losses as Circuit Breaker Halts Trading

South Korea bore the brunt of the selloff. The Kospi’s 8.3 per cent drop on June 8 wiped out much of its 20 per cent surge recorded in October, according to data from Business Insider. The circuit breaker mechanism halted trading for 20 minutes as the index plunged 8.8 per cent during morning hours.

Samsung Electronics, the world’s largest memory chip maker by revenue, tumbled 10.2 per cent. SK Hynix, a major supplier of high-bandwidth memory used in AI accelerators, fell 7.7 per cent. Battery manufacturer Samsung SDI declined more than 5 per cent, while display panel maker LG Display slid nearly 8 per cent.

Singapore’s Straits Times Index closed 1.7 per cent lower at 4,963.67 points. Chip-related stocks led losses: CSE Global dropped 3.6 per cent, AEM lost 3.1 per cent, and UMS Integration fell 1.2 per cent. CSE is an Amazon data centre partner, AEM supplies Intel, and UMS provides equipment to Applied Materials.

Banking stocks also declined. DBS fell 1.6 per cent to 62.76 Singapore dollars, OCBC dropped 2.3 per cent to 23.40 Singapore dollars, and UOB was down 2 per cent at 37.79 Singapore dollars.

Nvidia Memory Usage Report Sparks Fundamental Headwinds for Chipmakers

Swissquote analyst Ipek Ozkardeskaya wrote that the steep drop in memory chipmakers stemmed from fundamental headwinds, including reports that Nvidia’s next-generation Vera Rubin platform will use significantly less dynamic random access memory than earlier anticipated. This development threatens revenue projections for companies like Samsung and SK Hynix that had expanded production capacity in expectation of surging AI-driven demand.

Broader AI infrastructure spending may be losing momentum. Anthropic called for safeguards in early June that could halt frontier AI development, raising questions about the pace of future investment. Broadcom issued a cautious AI chip revenue outlook in its most recent earnings report, adding to investor concerns that the sector’s growth trajectory may be slowing.

Michael Burry, the hedge fund manager known for shorting the US housing market ahead of the 2008 crisis, disclosed short bets against Palantir and Nvidia on Monday. Veteran analyst Ed Yardeni wrote that investors sitting on substantial stock market gains may have taken profits in AI-related stocks in response to Burry’s filing news.

Similar patterns have emerged elsewhere as organisations navigate the challenges of deploying artificial intelligence at scale, including the governance challenges flagged by CIOs in recent enterprise surveys.

SpaceX IPO and OpenAI Filing Raise Capital Rotation Concerns

Investors are assessing whether a wave of major AI-related fundraising activity could divert capital away from existing publicly traded technology companies. SpaceX is expected to begin trading on Friday June 11 with a reported valuation near 1.75 trillion dollars, which would make it the largest initial public offering on record.

OpenAI confidentially filed for an IPO on Monday June 7, further fueling enthusiasm around AI-related investments. Some market participants view these transactions as additional catalysts for the AI investment cycle. Others worry that large capital raises at elevated valuations could absorb funds that might otherwise flow into listed technology stocks.

Mathieu Racheter, head of equity strategy research at Julius Baer, noted that Friday’s global selloff was heavily concentrated in crowded momentum stocks. Because the broader market remained largely resilient, Racheter characterised the drop as a healthy technical correction and a temporary breather within an ongoing bull market driven by strong corporate earnings.

Market watchers attribute the sweeping tech selloff to a massive liquidity rotation, especially out of South Korea. Ozkardeskaya said investors who rode the semiconductor wave could be taking profits and freeing up cash to jump into the SpaceX offering.

These rotation concerns echo workforce shifts observed in other parts of the tech sector, where companies are adjusting headcount in response to AI-driven changes.

Federal Reserve Rate Hike Fears Follow Strong US Jobs Data

The weakness in Asia followed a rough session on Wall Street. US-listed tech firms were affected on Friday by concerns of a possible Federal Reserve interest rate hike after a stronger-than-expected US labour report showed non-farm payrolls jumped by 172,000 in May, almost double consensus expectations.

Dario Messi, head of fixed income analysis at Julius Baer, noted that the blockbuster data fueled immediate fears of further central bank tightening. The US 10-year Treasury yield climbed back above 4.5 per cent while the two-year yield surged to 4.2 per cent.

Rising crude oil prices amid a fragile Middle East ceasefire are adding to inflation expectations. Markets are bracing for Wednesday’s US inflation report, which Ozkardeskaya expects to show headline inflation climbing to 4.2 per cent. That figure would significantly strengthen the case for an interest rate hike this autumn.

Concerns over the stability of a ceasefire between the US and Iran also weighed on investors, as Israel and Iran exchanged strikes on June 8 for the first time since a ceasefire in the Middle East war took effect two months earlier. Brent crude rose about 0.2 per cent toward 92 dollars per barrel as traders focused on ongoing diplomatic efforts.

This economic resilience presents an early policy headache for newly appointed Federal Reserve chair Kevin Warsh. David Kohl, chief economist at Julius Baer, pointed out that while solid job creation and elevated inflation challenge the view that current price pressures are purely transitory, the details of the labour report offer some comfort. Much of May’s hiring was concentrated in lower-paying leisure and hospitality roles ahead of the FIFA World Cup, keeping overall wage growth moderate and reducing the immediate risk of a wage-driven inflation spiral.

Japan and Taiwan Tech Stocks Extend Losses on Wednesday

Asian semiconductor and technology stocks resumed their decline on Wednesday June 10, tracking overnight weakness on Wall Street as AI valuation concerns continued to pressure chip names.

SoftBank Group plunged around 10 per cent amid a broader selloff in technology stocks and after Bloomberg News reported that efforts to secure at least 6 billion dollars through a margin loan backed by the company’s OpenAI stake had encountered difficulties. According to the report, the company is exploring alternative financing options but could revisit the loan proposal at a later stage.

Semiconductor equipment maker Advantest fell 3.8 per cent, while Renesas Electronics declined 3.4 per cent. In South Korea, SK Hynix dropped more than 8 per cent and Samsung Electronics fell 7.45 per cent on Wednesday.

Taiwan Semiconductor Manufacturing Co. fell about 2 per cent, while Hon Hai Precision Industry, a major Apple supplier, dropped more than 4 per cent. The losses came after a brief rebound in chipmakers lost momentum, with investors increasingly questioning whether the sector’s rapid gains have outpaced underlying fundamentals.

Chris Weston, head of research at Australian brokerage Pepperstone, wrote in a Wednesday note that the downturn reflected a gloomy and damp portrayal of risk. He added that there are not many reasons to buy in the current environment, and until markets move closer to Nvidia’s earnings on November 19, the market lacks a short-term catalyst.

Palantir and Nvidia Lead US Tech Declines Despite Solid Results

Shares of AI-powered data analytics firm Palantir tumbled 8 per cent on Tuesday following its third-quarter earnings report and Burry’s disclosure, despite solid results and upbeat guidance. Other major tech names including AMD, Oracle, and Nvidia also dropped, dragging the tech-heavy Nasdaq 100 down 2.1 per cent.

Louis Navellier, founder and chief investment officer at asset manager Navellier and Associates, wrote that there is fear of an AI correction, and if it comes, it will sweep the rest of the market with it due to the heavyweight of the leading names. He noted that while this earnings season featured companies consistently beating forecasts, investors are showing signs of resistance to high valuations. He still recommends Nvidia and Palantir.

Despite the selloff, Palantir’s stock remains up 152 per cent year to date, while Nvidia, which closed 4 per cent lower on Tuesday, is still up 48 per cent over the same period. Navellier wrote that markets were at all-time highs only last week, and profit-taking is the normal course of action.

Frequently Asked Questions

What triggered the Asian tech stock selloff on June 8?

The selloff was triggered by mounting investor concerns that AI-related valuations had run ahead of financial fundamentals. Reports that Nvidia’s next-generation platform will use less memory than expected added to fundamental headwinds for chipmakers. Strong US jobs data also raised fears of Federal Reserve interest rate hikes, while large upcoming IPOs from SpaceX and OpenAI fueled capital rotation worries.

Which Asian technology stocks were hit hardest?

South Korean chipmakers faced the steepest losses. Samsung Electronics fell 10.2 per cent and SK Hynix dropped 7.7 per cent on June 8. Japan’s SoftBank plunged around 10 per cent on June 10 after reports of difficulties securing a margin loan backed by its OpenAI stake. Taiwan Semiconductor Manufacturing Company declined approximately 2 per cent, while Singapore chip-related stocks CSE Global and AEM fell 3.6 per cent and 3.1 per cent, respectively.

How does the SpaceX IPO affect existing tech stock valuations?

Market analysts expressed concern that SpaceX’s expected June 11 debut with a reported 1.75 trillion dollar valuation could absorb significant capital and divert funds from existing publicly traded technology companies. Investors who rode the semiconductor rally may be taking profits to free up cash for the SpaceX offering, contributing to a liquidity rotation out of established chip stocks. OpenAI’s confidential IPO filing on June 7 added to concerns about competition for investment capital.

Conclusion

The sharp declines across Asian technology markets signal a fundamental reassessment of AI investment valuations after months of rapid gains. With Nvidia earnings scheduled for November 19, short-term catalysts remain scarce while macro pressures from potential Federal Reserve tightening and Middle East geopolitical tensions add to uncertainty.

Investors now face a critical test: whether current AI infrastructure spending levels can translate into revenue growth that justifies elevated stock multiples, or whether further corrections lie ahead as capital rotates toward high-profile offerings like SpaceX and away from publicly traded semiconductor names.
