Leadership map
Leaders: Korean growth shares, Singapore and Taiwan. Japan’s chip complex reversed early weakness.
Laggards: Hong Kong finished flat; Shenzhen remained softer.
Cross-asset pulse
Lower oil reduced pressure on Indian equities; falling U.S. yields helped global technology recover. Global markets · India
What changed
- Korea: The KOSPI erased a plunge exceeding 4% and closed higher; Samsung Electronics finished flat at ₩257,000 and SK hynix gained 0.42% to ₩1.678m.
- United States: The Nasdaq rose 0.66% before Nvidia’s results, while oil and Treasury yields fell. That is a friendlier handoff for Asia’s semiconductor exporters.
- India: Nifty rose 0.48%, but BSE breadth stayed negative: 2,007 advances versus 2,330 declines.
Immediate risk / reward
Lower yields and oil extend the overnight technology rebound; chip buyers defend Tuesday’s reversal into the Seoul and Tokyo opens.
Korea’s ₩3.95tn foreign selling resumes, exposing the rebound to another semiconductor-led air pocket.
KOSPI 6,408 intraday trough and 6,743 close; Nikkei 65,856; Brent near $89; foreign flow at the regular KRX open.
