South Korean financial authorities are reviewing measures to strengthen liquidity provider (LP) management for single-stock leveraged exchange-traded funds (ETFs) to prevent tracking error incidents that cause investor losses. The Financial Services Commission (FSC), Financial Supervisory Service (FSS), and Korea Exchange (KRX) are examining institutional improvements to stabilize tracking errors in Samsung Electronics and SK Hynix single-stock leveraged ETFs. The review follows an incident early last month when Korea Investment & Trust Management's 'ACE SK Hynix Single Stock Leverage ETF' surged approximately 50% despite the underlying SK Hynix stock falling nearly 8%, resulting in abnormal price execution during the closing auction period when market orders flooded in while bid-ask spreads widened significantly.
SK Hynix Leveraged ETF Records Abnormal Price Surge
Early last month, Korea Investment & Trust Management's 'ACE SK Hynix Single Stock Leverage ETF' closed trading at a price approximately 50% higher than the previous trading day, even though the underlying SK Hynix stock fell nearly 8%. Given the product structure, a decline of approximately 15-16% (twice the underlying asset's decline rate) would have been normal. The abnormal price execution occurred when a large volume of market buy orders flowed in during the closing auction period while bid-ask spreads were significantly widened.
Tracking error is an indicator representing the difference between an ETF's net asset value (NAV), which is its actual value, and the price traded in the market. As tracking error increases, investors face a higher likelihood of buying ETFs at prices above their actual value or selling at prices below their actual value.
LP Obligation Exemptions During Auction Periods Explained
According to the Korea Exchange LP business regulations, ETF LPs are not obligated to submit quotes during auction periods. LPs are not required to provide buy and sell quotes from 8:00 AM to 9:00 AM before market opening, for 5 minutes immediately after regular market opening (9:00 AM to 9:05 AM), and from 3:20 PM to 3:30 PM during the closing auction. This exemption considers that it is difficult to immediately hedge underlying asset price fluctuation risks at market opening and closing times, and that forcing quote submissions could result in unexpected losses for LPs or cause price distortions.
LPs are responsible for maintaining bid-ask spreads below a certain level during regular trading hours outside these exempted time periods, ensuring ETF prices remain close to net asset value. The problem arises when market orders concentrate during auction periods when LP quote gaps occur. If orders are executed without sufficient buy and sell quotes formed, ETF prices can deviate significantly from net asset value, causing tracking errors to expand rapidly.
Financial Authorities Review LP Evaluation Criteria Enhancements
Financial authorities are reviewing measures to strengthen the Korea Exchange's LP evaluation standards to prevent recurrence of such incidents. A plan to increase the weight of tracking error management in the quarterly LP evaluations currently conducted is under discussion. Authorities are also reportedly discussing measures to impose disadvantages on asset management companies that have experienced tracking error incidents during future new ETF listing review processes.
