Seoul Semiconductor Co. Ltd

Most Asia-Pacific markets fell today, with semiconductor stocks swinging wildly and tumbling sharply after US markets closed lower overnight amid concerns over stock valuations, fierce competition, and AI spending. South Korea's SK Hynix dropped more than 10%, even as quarterly profit surged 557% but missed analyst expectations, while Samsung Electronics fell over 4%, and LG Innotek and Seoul Semiconductor sank 9% and more than 6% respectively. Japanese chip names also declined, with Kioxia plunging 10%, Tokyo Electron down 8.5%, and SoftBank Group losing over 7%. China's ChiNext 300 index shed 1.83% and the Hang Seng China Semiconductor Chips Index slumped more than 5%, while Taiwan's TSMC eased 1.32%. Crude oil prices jumped nearly 4% after Middle East attacks shattered a brief calm amid US-Iran tensions, with WTI rising 3.09 dollars to 82.35 dollars a barrel and Brent adding 3.3 dollars to 87.39 dollars a barrel.

Asian technology stocks faced continued selling pressure in Wednesday trading, with semiconductor shares leading the market lower. Investors remain concerned about elevated valuations, intensifying competition in artificial intelligence, and the drag from a weaker US stock market overnight. In South Korea, SK Hynix, the world's major memory chip maker, tumbled more than 10% even after reporting record quarterly profit and revenue. The figures fell short of analyst expectations, triggering heavy selling. The pressure spread to other domestic tech names, with Samsung Electronics down over 4%, LG Innotek plunging more than 9%, and Seoul Semiconductor losing over 6%. In Japan, Kioxia dropped as much as 10%, Tokyo Electron fell 8.5%, and SoftBank Group declined more than 7%. In Taiwan, TSMC slipped 1.32%. In China, the ChiNext 300 Index lost 1.83% and the Hang Seng China Semiconductor Chips Index sank more than 5%, underscoring the broad regional sell-off. Bucking the trend, Chinese internet stocks listed in Hong Kong moved higher, with Tencent up 3.6% and Meituan gaining 2.7%, while Alibaba, Baidu, and Kuaishou also traded in positive territory.
