ChainCatcher 消息，彭博数据显示，韩国综合指数（KOSPI）今年以来收益波动率达到 63%，超过同期比特币的 48%，成为彭博追踪主要国家股指中波动率最高的市场。韩国股市高波动主要源于市场集中度过高。三星电子和 SK 海力士合计占据 KOSPI 指数超过 50%权重，使指数走势高度依赖半导体板块表现。
此外，韩国散户主导的杠杆 ETF 市场进一步放大了市场波动。相关杠杆 ETF 与两大芯片股一度占据韩国股市超过 70%的日成交额。数据显示，韩国散户今年累计买入超过 110 万亿韩元（约 770 亿美元） 的 KOSPI 股票，但其追涨杀跌行为也加剧了市场震荡，使韩国股市逐渐成为围绕三星电子和 SK 海力士展开的高杠杆交易市场。
