SK Hynix leveraged ETF reshapes global chip stock volatility

A leveraged exchange-traded fund tracking SK Hynix has grown so large and so fast that it is now mechanically amplifying volatility across South Korean and global technology stocks, raising alarms among regulators, analysts, and even the fund's own management.

A $17 Billion Tail Wagging the Dog

The CSOP SK Hynix Daily (2x) Leveraged Product, launched on the Hong Kong Stock Exchange in October 2025, surpassed $16.8 billion in assets under management by June 22, overtaking the Tracker Fund of Hong Kong to become the city's largest ETF. The fund has returned nearly 900% year-to-date, fueled by roughly $2 billion in inflows and the rest from market appreciation, according to Bloomberg Intelligence analyst Rebecca Sin.straitstimes+1

On volatile trading days, the ETF and similar leveraged products account for up to two-thirds of SK Hynix's total trading volume. Strategy analysts estimate that for every 1% market move, leveraged ETFs may trigger approximately $9 billion in rebalancing demand. CSOP CEO Ding Chen has acknowledged the trade has become "very, very crowded", though he previously argued the fund's impact on the broader market was overstated.kucoin+2

The June 23 Crash and Global Contagion

The consequences became starkly visible on June 23, when South Korea's Kospi plunged nearly 10% — its worst single-day drop in more than three months — triggering a market-wide circuit breaker. SK Hynix and Samsung Electronics each fell more than 12%. Leveraged ETFs tracking the two chipmakers were forced to sell an estimated $6 billion in shares that day to maintain their 2x ratios, representing about 14% of total turnover in both stocks.reuters+2

The selloff spread rapidly. The Nasdaq 100 declined more than 2%, while the S&P 500 fell 1.44%. CNBC reported that the rout intensified as investors rotated out of "Magnificent Seven" stocks.cnbc+1

Regulator Regret and Structural Risks

The catalyst for the June 23 crash was a briefing from Financial Supervisory Service Governor Lee Chan-jin, who said he wished he had done more to block the late-May launch of 16 single-stock leveraged ETFs tracking Samsung and SK Hynix. Those domestically listed funds swelled from $3 billion at launch to roughly $9.1 billion within weeks, with 92% of holders being retail investors.investing+1

"These are high-risk products," Lee said. "Despite consumer warnings, trading hasn't cooled".investing

Analysts warn that the structural risk remains. A momentum reversal could trigger cascading forced selling given the outsized rebalancing flows, while the concentration of South Korea's benchmark — SK Hynix accounts for roughly 28% of the Kospi and Samsung about 29% — means leveraged products tied to just two stocks can move the entire index. With SK Hynix preparing a landmark Nasdaq ↗ 2.33% listing on July 10 that could raise $29.4 billion, the intersection of leverage, concentration, and global investor appetite for AI exposure shows no sign of unwinding quietly.bloomberg+1
