On the 6th, Asian stock markets are showing a sharp decline in the aftermath of the New York Stock Exchange's selloff of artificial intelligence (AI)-related stocks last night.
The Nikkei 225 index, centered on Japanese technology stocks, plunged 7% immediately after opening, but then narrowed the decline and was traded at 57,438.00, down 6.0% as of 2 p.m. The Topix index also fell 6.2%.
Bloomberg News reported that Nikkei is poised to record its largest daily decline since April of last year.
Softbank Group plunged 15.8% and Kioxia 15.3% immediately after opening, but then narrowed the decline and fell 10.6% and 10.0%, respectively.
Taiwan's Jiquan Index is trading at 39,996.07, down 3.8%.
Immediately after opening, it plummeted 3,737.67 points (9.0%), recording the largest intraday drop in history.
TSMC, which accounts for more than 40% of the market capitalization, was once pushed to the -10% lower limit (NT$2,020), but then narrowed the decline to NT$2,145, down 4.2%.
KOSPI also plunged by 8.8% during the day, dropping 5.1% to 5,109.73 after the circuit breaker was activated.
On the other hand, the decline in the Greater China region was relatively small. Hong Kong's Hang Seng Index fell 1.3%, the Shanghai Composite Index fell 1.3%, and the Keqiang Ban (Science Startup Edition) STAR50 Index fell 2.5%.
It was analyzed that the Democratic Party's landslide victory in the U.S. midterm elections raised concerns about strengthening AI regulations and a slowdown in data center construction, and that the decline increased due to leverage and forced liquidation.
“There is definitely an element of panic in the selling, and the positioning is making the correction much more intense,” said Charu Chanana, chief investment strategist at investment bank Saxobank.
