Global Tech Sell-Off Hits Asia as Nasdaq Crash Spreads

Global Tech Sell-Off Deepens as Asian Markets Tumble After Nasdaq Rout

Asian equity markets opened the week under heavy pressure as a global technology sell-off intensified, following Friday’s sharp decline in the US Nasdaq Composite. The downturn triggered widespread losses across major Asian indices, led by a steep fall in South Korea’s benchmark Kospi.

South Korea Leads the Decline

South Korea’s Kospi index plunged as much as 8.8% in early trading, forcing a 20-minute trading halt as panic selling swept through the market. Heavyweight semiconductor stocks bore the brunt of the sell-off:

• Samsung Electronics dropped more than 10%

• SK Hynix also fell by over 10%

Together, these chip giants account for nearly 40% of the Kospi, amplifying the index’s decline. Although the index later recovered slightly, losses remained above 5% intraday.

Broader Asian Markets Under Pressure

The weakness was not limited to Seoul. Other major Asian indices also recorded sharp declines:

• Japan’s Nikkei 225: down 3.9%

• Japan’s Topix: down 2.6%

• Taiwan’s Taiex fell as much as 6%, led by chipmaker pressure

• Hong Kong Hang Seng: down around 1%

• China’s CSI 300: down about 1.5%

Markets with heavier exposure to semiconductor and AI-related stocks saw the steepest losses.

What Triggered the Global Tech Slide?

The sell-off followed a 4.2% drop in the Nasdaq Composite, its worst session since April last year. The US decline was driven by concerns that:

• AI-driven tech valuations had become overstretched

• Semiconductor stocks were overbought

• Recent earnings signals showed mixed demand trends

The S&P 500 also fell 2.6%, ending its nine-week winning streak and adding to global risk-off sentiment.

???? Pressure on Semiconductor Stocks

Analysts point to several recent developments that weighed on chip stocks:

• Weaker-than-expected earnings from Broadcom

• Concerns over memory chip supply-demand dynamics in the US

• Adjustments in Nvidia’s future production roadmap for its Vera Rubin platform

However, market experts from Nomura noted that these signals do not necessarily indicate weak demand. Instead, they suggest:

“The memory-related newsflow does not point to weaker demand… rather it reinforces a structural supply shortage.”

Currency and Policy Response in South Korea

The sell-off also hit South Korea’s currency markets, with foreign investors reportedly selling around $10 billion worth of Korean equities in a week, putting pressure on the won, which hit its weakest level since 2009.

In response, South Korea’s authorities:

• Held an emergency market stability meeting

• Announced measures to support the currency

• Vowed action against speculative trading

President Lee Jae Myung also stated that despite recent volatility, the domestic stock market remains “undervalued” following its strong rally earlier this year.

Market Outlook

The sharp correction highlights growing sensitivity in global markets to:

• AI and semiconductor valuation cycles

• US tech earnings momentum

• Foreign capital flows into Asian equities

Investors are now watching whether this is a short-term correction or the beginning of a broader re-rating in global technology stocks.
