Single-stock leveraged exchange-traded funds are nearing launch in South Korea, with listing expected on May 22, the financial investment industry said. Products tracking an individual stock’s return at twice the daily rate, and possibly inverse products, will be allowed. Eligibility is limited to stocks meeting market-cap and trading-volume thresholds, which currently only Samsung Electronics and SK Hynix satisfy. Market participants warn the new products could intensify flows into large semiconductor shares and increase risks associated with leverage.
