Investing.com– Asian stocks were mixed on Thursday, as a sharp selloff in semiconductor shares triggered a trading curb in South Korea, offsetting support from a steep decline in oil prices after Democrats’ victories in the U.S. midterm elections.
U.S. stock futures were also mixed during Asian hours by 03:48 GMT, with tech-heavy Nasdaq 100 Futures leading losses. Wall Street closed higher overnight as investors welcomed the prospect of Democrats gaining control of Congress.
S.Korea, Japan chip stocks slide; KOSPI entered trading halt
South Korea’s KOSPI fell as much as 5.2%, triggering a five-minute sell-side trading curb, known as a sidecar, as a sharp selloff in semiconductor stocks intensified.
Heavyweight chipmakers Samsung Electronics (KS:005930) and SK Hynix Inc (KS:000660) slumped 5.5% and 8%, respectively.
The losses came as disappointing earnings from U.S. chip designers Qualcomm (NASDAQ:QCOM) and Arm Holdings (NASDAQ:ARM) revived concerns over the semiconductor industry’s growth outlook. The Philadelphia Semiconductor Index had dropped 3.1% overnight to a six-month low.
Chip equipment makers also came under pressure, reflecting concerns about weaker smartphone demand, rising memory costs and uncertainty over the returns from massive artificial intelligence investments.
Japan’s Nikkei 225 edged down 0.3%, while the broader TOPIX index rose 1.5%.
Japan’s chip and artificial intelligence-related shares also extended their losses on Thursday, following a steep selloff in the previous session. Chip-testing equipment maker Advantest (TYO:6857) fell 9.4%, while semiconductor equipment manufacturer Tokyo Electron (TYO:8035) dropped 7.7%. Technology investor SoftBank (TYO:9984) declined 5.3%.
China stocks outperform on tech gains
Chinese stocks bucked the regional technology selloff, with semiconductor shares advancing as Beijing’s fresh support measures boosted investor appetite for domestic chipmakers.
The blue-chip Shanghai Shenzhen CSI 300 index rose 0.4%, while Shanghai Composite rose around 0.1%.
Hong Kong’s Hang Seng index jumped 3.5% with Chinese chipmaking stocks leading gains.
Chinese semiconductor shares benefited from the People’s Bank of China’s decision to cut the interest rate on its relending facility for share buybacks and share purchases by 25 basis points to 1%.
