【当大涨大跌成为家常便饭 韩国股市逐步“迷因化”】韩国基准股指的波动已达到极端水平，以至于投资者和分析师将市场日内剧烈波动与“迷因股”狂热相提并论。尽管考虑到Kospi指数有全球领先的芯片制造商的强劲盈利作为支撑，这种比较乍听之下或许有些夸张，但并非毫无道理。散户投资者的兴趣不断升温，今年Kospi指数已有20个交易日收盘涨跌幅至少达到5%，而2025年全年仅有2次。三星电子今年已出现8个交易日涨跌幅达到或超过10%，而去年为0次；SK海力士今年则有11次，而2025年为2次。这令人联想到以前游戏驿站和Bed Bath & Beyond等股票被散户狂热追捧时的景象。波动性飙升的一大推手是散户对个股杠杆型ETF的疯狂买入。此外，以上两大权重股的主导地位日益增强也加剧了波动。据高盛估计，韩国股市5%的波动可能引发约47亿美元的ETF调仓资金流，因为期权交易商需要调整风险敞口。这一规模相当于韩股正常交易日成交量的约八分之一。
