KOSPI Rises on Foreign Buying and Chip Rebound

That matters because the rally is not just a one-off tech pop. A sustained advance in Korea’s market typically depends on foreign inflows, especially in heavyweight semiconductors that dominate index direction and global investor positioning. When overseas buyers rotate into Samsung and SK hynix, they can move the entire benchmark, improve liquidity and lift sentiment toward the broader Korean equity market.

The move also reflects a friendlier global backdrop for risk assets. Renewed optimism around artificial intelligence demand has helped keep chip stocks in favor, while a stronger-than-feared U.S. labor market has eased recession worries and reduced pressure on the Federal Reserve to tighten aggressively. That combination has supported Asia equities even as geopolitical tensions remain in the background.

For investors, the key question is whether this is the start of a durable foreign-led re-rating or just another short-lived burst in a volatile market. Samsung’s RSI at 59.8 and SK hynix’s RSI at 69.3 suggest momentum is still constructive, while both stocks have recently pushed back toward their Bollinger Bands’ upper range — a sign traders are pressing the rally rather than abandoning it.

Still, the KOSPI’s next move likely depends on whether foreign funds continue to buy into the semiconductor cycle and whether global growth data stay firm enough to keep AI-related trade alive. Any reversal in dollar strength, U.S. rates expectations or chip sentiment could quickly test whether the market can hold the baton without domestic support.
