The power of the "world's largest leveraged ETF": The "2x SK Hynix ETF" not only affects SK Hynix, but even influences the performance of global technology stocks as a whole.
```
Leveraged ETFs tracking individual technology giants are evolving from passive investment tools into core engines amplifying global market volatility. With highly concentrated capital, these products not only magnify the ups and downs of underlying stocks and benchmark indices, but their chain reactions are spreading to global tech stocks.
Last week, South Korea's Kospi index plunged 10%, triggering a global sell-off in tech stocks and dragging the Nasdaq down by 3%. This sharp volatility highlighted the significant influence of the CSOP SK Hynix Leveraged ETF. In just nine months since its launch, the fund's size has ballooned to $13 billion, making it the largest product of its kind in the world.
On July 2, according to Bloomberg, on highly volatile days, the ETF and similar, smaller funds can account for up to two-thirds of SK Hynix's total daily stock trading volume—a staggering figure for a company with a $1.2 trillion market cap—forcing major banks from Wall Street to Hong Kong to carefully engineer complex financing and hedging trades to keep these products functioning.
As investors rush to bet on the AI boom, global leveraged ETFs have grown into a massive $270 billion industry. Analysts warn that this one-sided positioning is creating a feedback loop that, should market momentum reverse, could trigger rapid sell-offs as ETFs mechanically rebalance, posing a direct threat to broader markets.
Ballooning Scale Reshapes One-Day Trading Structure
The CSOP SK Hynix ETF has about $13 billion in assets, roughly twice the average daily trading value of SK Hynix’s stock. Among leveraged ETFs tracking large-caps, this is the most extreme level. SK Hynix makes up 28% of the Kospi index, and its competitor Samsung Electronics accounts for 29%, making the stock an increasing barometer for global AI bubble concerns.
According to the report, the sheer size has changed how professionals trade the stock. According to market maker Ian, every day around 1:30 pm, traders start buying and selling SK Hynix stock in anticipation of rebalancing by leveraged funds, and then close positions before the market close. Estimating this ETF’s end-of-day rebalancing size has become as important as analyzing company earnings prospects on many trading desks.
Every afternoon, a vast network of banks, hedge funds, and market makers starts preparing for the fund’s rebalancing. CSOP has listed over 20 counterparties supporting the ETF, including major Wall Street names like Goldman Sachs and Morgan Stanley. Banks provide swaps to create leverage, while hedging risk through exotic derivatives called “cliquets” and managing SK Hynix stock, futures, and options positions.
Surging Hedging Costs and Systemic Pressure
As the product grows, the cost to keep this world’s largest single-stock leveraged ETF running is surging, and the pressure is beginning to show within the financial system.
According to reports, banks offering swap agreements are facing funding constraints. Some are cutting back their risk exposure on SK Hynix or charging clients higher fees; others are urging asset managers to hold stocks directly and enter swap arrangements with the banks. Bloomberg data shows the annualized cost for “cliquet” derivatives used to hedge SK Hynix price crashes has soared from around 3% in March to over 10%.
The cost increases have directly impacted the fund’s performance. According to Bloomberg Industry Research, as of June 29, the ETF’s return for the year was 718%, while a theoretical portfolio offering a perfect compounded 2x daily exposure should have returned about 921%. This gap reflects the rising cost of locating and hedging exposures. CSOP has repeatedly warned investors that if counterparties hit their risk limits, creation of new ETF shares may be suspended.
Janus Henderson portfolio manager Jamie Sandells said:
“This is a terrible time for banks’ balance sheets. We’re facing record stock market highs, large IPOs, and now the leveraged ETF story on top of it all.”
Crowded Trades and Potential Sell-Off Risks
With funds pouring in, the market is increasingly wary of how crowded this trade has become. The report notes that CSOP CEO Ding Chen recently admitted the trade is now “very, very crowded,” but said the company has strengthened risk controls as the fund expands.
Lotus Asset Management Ltd. CIO Hao Hong said he sold all his CSOP ETF positions accumulated since January because the trade became too crowded and technical indicators turned red across the board. He noted SK Hynix’s relative strength is fading—a pattern that typically signals an imminent price correction or consolidation.
The greater risk lies in mechanical sell-offs during momentum reversals. Macro Risk Advisors CEO Dean Curnutt noted that high tech stock returns create a feedback loop on the way up but will work the same in reverse when the market falls.
Declines in SK Hynix and the Kospi index could trigger “very large and very rapid sell-offs.” If there’s an event like the ETF’s 23% plunge on June 23 that lasts long enough, even more pain could hit markets.
Meanwhile, the surge in leveraged ETFs is attracting global traders and regulators' attention. Nomura strategists estimate that for every 1% market swing, leveraged ETFs now generate about $9 billion in rebalancing needs. Barclays estimates that recent U.S. leveraged ETF rebalancing volumes have climbed to several times the long-term average, with buy and sell flows enough to affect broader market trading.
In South Korea, regulators have expressed regret over approving 16 copycat leveraged ETFs tracking its biggest chipmaker in May, saying these products have exacerbated market volatility. Data shows that over 90% of investors in these funds are retail traders.
Analysts point out that if SK Hynix experiences a prolonged slump, ETFs will be forced to sell mechanically in a falling market, and given its massive Kospi weighting, such pressure could quickly spill over to index futures and other derivatives linked to South Korea’s market (now the world’s seventh largest).
Still, analysts say SK Hynix’s planned $29 billion U.S. listing may boost liquidity in its stock, easing some of the shock caused by leveraged ETF fund flows.
