Seoul stock index climbs for a fourth day on semiconductor rally

South Korea's primary equity benchmark posted another increase, delivering a fourth consecutive session of gains. The advance was led by semiconductor firms, whose shares surged on reports of solid demand for both memory and logic chips. This sector strength compensated for softer performance in other industries, keeping the overall index in positive territory.

Market participants highlighted the chips rally as a sign of resilience amid global supply-chain challenges. Trading activity was modest, suggesting that the rally is being driven more by price appreciation than by heavy buying volume. Analysts warned that the upward trend could face headwinds if export demand eases, but one outlet momentum remains supportive of the market.
