Market Volatility and Disruptions in Trading US ETFs

Amidst recent sharp fluctuations in domestic and international stock markets, the deviation rates of Korean ETFs have significantly increased. On the 5th, when the KOSPI plummeted by 8.77%, there were 260 disclosure notices of excessive deviation rates, particularly pronounced in tech-themed ETFs and derivative products. The 'TIGER Philadelphia Semiconductor Leveraged ETF' recorded the highest deviation rate of 17.90%, urging investors to exercise caution.
The sudden market volatility has also caused disruptions in Korean securities firms' weekly trading services for US stocks, with system issues originating from the American alternative trading system Blue Ocean. Blue Ocean notified its partner securities firms that only a limited number of ETFs could be traded, excluding popular semiconductor ETFs favored by domestic investors. Many orders were unilaterally canceled by Blue Ocean, leading to canceled profits and losses, and investors are filing complaints with the Financial Supervisory Service and preparing lawsuits against the securities firms.
This issue has persisted for three days, with eligible trading stocks including 'QQQ', 'TQQQ', 'SQQQ', 'SPY', 'TLT', and 'XLK', while 'SOXX', 'SOXS', 'SOXL' are excluded. Blue Ocean has yet to clarify the reasons, exacerbating investor confusion and anxiety.
