The KOSPI surged more than 5% in the regular session on the 20th, recovering the 6,800 level. Nine of the top 10 stocks by market capitalization closed higher, with the exception of Hanwha Aerospace, as strong buying swept across large-cap stocks overall.

【Intraday Break Above 6,900... Buy-Side Sidecar Triggered】 The KOSPI finished the day at 6,852.58, up 381.41 points (5.89%) from the previous trading day. It even broke above the 6,900 level intraday, and a buy-side sidecar was triggered due to the rapid index rise, showing a strong trend.

【Semiconductor Stocks Lead... 9 of Top 10 by Market Cap Rise】 Among top market-cap stocks, semiconductor shares stood out with their gains. Samsung Electronics closed at 271,000 won, up 23,500 won (9.49%) from the previous session. SK Hynix finished trading at 1,691,000 won after soaring 191,000 won (12.73%), posting a double-digit gain.

Samsung Electronics Preferred also closed up 10.07% at 191,200 won, while SK Square rose 11.85% to 1,123,000 won.

【Hanwha Aerospace, the Only One Slightly Lower】 Meanwhile, Hanwha Aerospace was the only one among the top 10 market-cap stocks to end slightly lower. It closed at 1,167,000 won, down 10,000 won (0.85%) from the previous trading day.

【Focus on Reclaiming the 7,000 Level... Caution Advised on Short-Term Swings】 Large-cap stocks, including Samsung Electronics and SK Hynix, rose across the board, lending strength to the index rebound. The fact that nine of the top 10 stocks by market capitalization closed higher also underscored the market's strong mood.

However, as index volatility has increased in the domestic stock market recently, caution is needed regarding the possibility of sharp short-term swings. With the KOSPI rebounding sharply, attention is now focused on whether it can reclaim the 7,000 level and whether the upward trend in large-cap stocks will continue.
