Korean Retail Investors Poured Over 300 Billion Won into Samsung and SK Hynix Leveraged ETFs in October
nashnova research
Korean retail investors net-bought ₩315.4 billion in leveraged ETFs tied to Samsung Electronics and SK Hynix in October — the first net-buy swing since regulators tightened margin rules in late July — betting that a near-19% KOSPI slide marks the bottom for chip stocks.
Where did the money go?
Retail investors net-bought 14 single-stock leveraged ETFs for a combined ₩315.4 bn: seven SK Hynix products drew ₩226.3 bn, seven Samsung products drew ₩89.1 bn.
This means → retail is betting on Hynix at roughly 2.5 times the rate it is betting on Samsung.
The single largest magnet was KODEX SK Hynix Leveraged, which pulled in ₩152.9 bn — 11th among all listed Korean ETFs.
Just single-stock leverage — or broader bets too?
Retail also swept up broad-market leveraged products: KODEX Leverage drew ₩1.045 trillion; KODEX Semiconductor Leverage drew ₩256.4 bn.
In plain terms = they are not just betting on one stock — they are betting the entire chip sector bounces.
Korean investors net-bought $4.89 bn in U.S. equities over the same period; $3.55 bn — or 73.9% — went into SOXL, a 3× bull semiconductor ETF.
Why did they come back in October?
In July, retail net-bought these same 14 products for ₩2.773 trillion in a single month. After regulators raised margin requirements on July 31, retail flipped: net-selling ₩648.4 bn in August and ₩497.9 bn in September.
By October, KOSPI had fallen a cumulative 18.83%, and some retail investors concluded prices were near a floor.
This reflects a clear behavioral trigger: retail exits when regulations tighten, then piles back in once a big enough drawdown makes the urge to bottom-fish irresistible.
What is the biggest risk of bottom-fishing with leveraged ETFs?
Leveraged ETFs — funds that track a daily multiple of an underlying asset's return — amplify gains and losses equally.
In plain terms = if a stock drops 10% then rises 10%, it is roughly back where it started — but a 2× leveraged ETF would still show a loss. That gap is the negative compounding effect.
This means → in a choppy market with repeated swings, holding a leveraged product can lose money even if the investor ultimately guesses the direction right. Whether retail's renewed bet pays off before volatility erodes it remains the single biggest unknown.
