Seoul stocks opened sharply lower on Monday as investors moved to lock in profits following a record-breaking surge in the previous session.
The benchmark Korea Composite Stock Price Index (KOSPI) opened down 237.18 points, or 3.6 percent, at 6,358.27 at the opening bell. The KOSPI is South Korea's primary stock market index, comprising all common stocks traded on the Korea Exchange.
The decline bucked a rally on Wall Street on Friday (local time), where robust earnings from Amazon fueled investor optimism for the artificial intelligence (AI) sector. Revenue at Amazon's cloud computing unit, Amazon Web Services, jumped 37 percent in the second quarter ending in June, exceeding market expectations. That momentum, however, did not carry over to Seoul, where the KOSPI is heavily weighted toward large-cap technology and semiconductor names that can amplify both upside rallies and subsequent pullbacks.
The sharp pullback comes after the KOSPI vaulted approximately 17 percent on Friday, marking the sharpest single-day gain on record for the index. For context, the Korea Exchange imposes daily price limits of 30 percent on individual stocks, meaning Friday's index-level move represented an unusually broad market advance approaching that ceiling.
"We may see investors attempt profit-taking early this week, as the benchmark KOSPI vaulted around 17 percent Friday, the sharpest single-day gain on record," said Han Ji-young, an analyst at Kiwoom Securities.
The sell-off illustrates how rapidly markets can reverse course even amid positive global signals. Profit-taking is a common market behavior in which investors sell shares after a significant price increase to realize gains, often putting downward pressure on prices in the short term.
The KOSPI's record single-day surge on Friday was itself an extraordinary event for South Korean equities, far exceeding typical daily movements for the index, which historically fluctuate within a much narrower range.
