On July 7, Direxion Daily South Korea Bull 3X Shares (KORU) fell 13.65% in regular trading, trading at $540.63/share, with turnover of $355 million.

On the news front, the Korean KOSPI index plunged nearly 5% on the day, diving as much as 8.2% intraday and triggering the circuit breaker mechanism — the sixth activation this year and the twelfth in history. Samsung Electronics and SK Hynix both tumbled over 10% intraday, dragging the broader market sharply lower. The selloff was fueled by mounting doubts over the sustainability of record AI-driven earnings for chipmakers, with Morgan Stanley noting semiconductor momentum is fading as capital rotates toward cloud hyperscalers and defensive sectors.

Despite Samsung Electronics reporting Q2 operating profit of 89.4 trillion won — an 1,810% year-over-year surge that beat estimates — the market treated the result as a sell-the-news event after massive year-to-date gains. The KOSPI has now retreated 16% from its June 22 all-time high, though it remains up 82% year-to-date. As a triple-leveraged product, KORU mechanically amplified the underlying index decline.
