受近期人工智能热潮带来的收益驱动，投资者开始获利回吐，6月26日韩国综合股价指数（KOSPI）下跌5.81%，收于8411.21点。
韩国交易所于上午11时13分左右启动了卖方“侧车”（sidecar）机制，在KOSPI 200指数期货下跌超过5%后，暂停程序化交易五分钟。随后，当股指跌幅超过8%时，交易所于中午12时10分触发熔断机制，交易暂停20分钟。
外资和机构分别净卖出4.6万亿韩元和3.8万亿韩元，而个人投资者净买入8.2万亿韩元。三星电子股价收跌5.3%至339,500韩元，SK海力士股价下挫8.36%至267万韩元。
基宇证券（Kiwoom Securities）分析师韩智英（Han Ji-young）表示：“投资者担心存储芯片价格过高会推高终端产品价格，从而削弱对存储芯片的需求。”韩元兑美元汇率走强至1,532韩元兑1美元。
社交平台X上的初步反应强调，三星和SK海力士等人工智能相关股票的获利回吐推动了KOSPI指数的急剧下跌，市场对半导体行业的市场波动、杠杆率及泡沫风险表示担忧。

KOSPI halted at -8% isn’t random. This is the overheated AI trade hitting reality -> extreme concentration in Samsung & SK Hynix + crazy Korean leverage = extreme volatility 🚨
