A Smartkarma report by a derivatives and quantitative strategist says 2x
single-stock ETFs tracking Samsung Electronics and SK Hynix must rally roughly
33% to recover June 22 levels, implying the underlying shares need about a 16.5%
rise. Both chipmakers fell double digits on Tuesday, knocking the linked ETFs
down about 25%; the Samsung 2x ETF is down 5.4% since its May 27 launch. The
report warns Korea’s single-stock 2x ETFs boost returns in trending markets but
quickly erode value in high volatility, making them best suited to short-term
tactical momentum trades.
