On May 22, a product will debut on the Korean stock market that moves 2% when Samsung Electronics rises 1%, and also moves 2% when it falls 1%.
SK hynix will be the same. For the first time in Korea’s capital market history, the door is opening to leveraged and inverse listed products based on a single stock.
Even though there are still three weeks until launch, applications for pre-launch education lined up on the very first day. It is a scene that vividly reveals the market’s temperature.
According to the Korea Financial Investment Association, 2,056 people applied on April 28, the first day pre-education for single-stock leveraged and inverse products opened. On the same day, 1,654 people completed the training. There is now less than a month left until launch. Inside and outside the association, some predict that the number of applicants will swell into the tens of thousands right before release.
The warning signs had already been flashing for a long time. From January 1 to April 28 this year, 521,564 people completed the existing leveraged ETP pre-education. That is more than 13 times the number from the same period a year earlier. It is a figure that clearly shows why Korean retail investors are called the “leverage nation.” Single-stock leverage is an even riskier product layered on top of that.
The new product created by the semiconductor boom
The trigger was the surge in those two stocks. Over the past year, Samsung Electronics shares have risen 308.7%. SK hynix has jumped 604.4%. The memory boom driven by soaring demand for artificial intelligence semiconductors and high-bandwidth memory (HBM) pushed up the two companies’ market capitalizations. On top of that rally, demand emerged from investors wanting to ride it with 2x leverage.
This is also the rationale the Financial Services Commission used to allow single-stock ETFs: to bring demand for blue-chip domestic stocks into a legal framework. Until now, Korean retail investors had been indirectly accessing such exposure through U.S. single-stock leveraged products.
Direxion’s 2x leveraged Tesla fund (TSLL) and GraniteShares’ 2x leveraged Nvidia fund (NVDL) are representative examples. According to data from the Korea Securities Depository, TSLL and NVDL have consistently ranked among the top holdings by Korean overseas investors.
The authorities’ calculation is that capital that had flowed overseas could be brought back into the domestic market. But there is also a trap in that calculation. With losses already piling up from overseas leveraged products, opening the same structure domestically could merely shift the loss cases from the U.S. to Korea.
The negative compounding effect: what happens over one year?
The biggest trap of leveraged products is the “negative compounding effect.” Because they track twice the daily return, losses accumulate disproportionately whenever the market moves sharply over just a few days. If a stock starts at 100 and falls 10% one day, then rises 10% the next, a normal stock ends at 99, but a 2x leveraged product falls to 96. The longer the holding period, the larger the gap becomes.
According to an analysis by researcher Kwon Min-kyung at the Korea Capital Market Institute of leverage and inverse ETFs tracking the KOSPI 200, many individual investors recorded continuous losses, including on the day of purchase.
The U.S. Securities and Exchange Commission has also officially warned that leveraged ETFs are not suitable for long-term investment. Because of the daily tracking structure, holding them for anything other than short-term trading statistically increases the likelihood of losses.
The problem is that Korean retail investors’ holding patterns often diverge from the statistics. Many buy with the intention of short-term rotation trading but end up holding on after losses.
There have also been repeated cases of overseas investors entering NVDL in anticipation of Nvidia’s strong earnings, only to be swept up by short-term volatility and suffer losses. Single-stock leverage is even more volatile, so the negative compounding effect is stronger as well.
Concerns over blue-chip concentration and market distortion
Stocks eligible for single-stock leverage must pass strict criteria. They must account for at least 10% of average market capitalization and at least 5% of average trading value. In practice, only Samsung Electronics and SK hynix qualify. This means capital is being concentrated even more heavily into the top two companies by market capitalization in the KOSPI.
Korea’s stock market is already overwhelmingly dominated by the two semiconductor leaders. If additional 2x leveraged money flows in, volatility in those two stocks will become even greater. If concentration in a few names intensifies, the price-discovery function of the overall market weakens. If forced selling piles up all at once, short-term shocks will also be larger.
The decision to prohibit the use of “ETF” in the product name and require the term “single stock” reflects these concerns. A standard ETF must diversify across at least 10 holdings, whereas a single-stock leveraged product has no diversification effect at all. The naming convention will therefore be set not as “Samsung Electronics 2x leveraged ETF” but in the form “asset manager-stock name-single stock-2X-leverage.”
Is one hour of pre-education enough?
This single-stock leveraged product adds one hour of advanced education on top of the existing leveraged ETP training. New investors must complete a total of two hours before they can trade. The core risks covered include the negative compounding effect and leverage. Key quizzes and pre-investment checklists are also included.
The question is whether one- to two-hour video education can adequately make investors aware of the risks of high-risk derivatives. In the United States, the SEC has repeatedly warned from the earliest days of single-stock leveraged products that they are “not suitable for ordinary investors.”
Academics have increasingly argued that simple information delivery is not enough and that investor suitability testing is needed. The current structure, which grants buying permission with only a one-hour completion certificate, is viewed as little more than a formal procedure.
The fact that investors with overseas trading experience are exempt from the advanced education is also controversial. Domestic and overseas markets differ in trading hours, settlement structure, and taxation. That is why the industry argues that separate education tailored to Korea’s market environment is necessary even for the same leveraged product.
Where is the solution?
There is no single prescription. But the starting point that experts consistently point to is clear: the first task is to move beyond the formality of pre-education and make it effective.
One alternative being discussed is to require not only video explanations of the negative compounding effect but also simulated trading practice and risk scenario simulations. Measures such as the “suitability pre-assessment” adopted by some U.S. brokerages are also under review.
Differentiated initial deposit requirements should also be on the table. At present, leveraged ETPs require a base deposit of 10 million won. Because single-stock leverage carries a higher risk profile, some argue that the deposit threshold should be raised or trading limits applied differently. Japan and Hong Kong mandate separate suitability assessments for high-risk derivatives.
Warnings about long-term holding should also be strengthened at the product design stage. One proposal is to require disclosure on the purchase screen of information such as “average holding period” and “negative compounding accumulation simulations.” Behavioral economics research has shown that information presented right before purchase is more effective in changing behavior than post-purchase education.
Reworking the entry barriers for the products themselves should not be overlooked. There are calls to add volatility indicators to the criteria for stocks eligible for single-stock leverage, beyond market capitalization and trading value. Because greater volatility accelerates the negative compounding effect, a volatility threshold could serve as a practical safeguard.
The remaining task
The launch of single-stock leverage is a new test for Korea’s capital market. The challenge ahead is to strike a balance between absorbing capital that had flowed overseas and preventing individual investors from being exposed to risk without protection.
The sight of more than 2,000 pre-education applications in a single day is both a sign of market vitality and a warning light. The fact that leveraged education completions have grown 13-fold sends an even stronger signal.
There is not much time left until May 22. The tasks to be solved by then are clear: making pre-education effective, mandating disclosure of loss scenarios by holding period, differentiating initial deposit requirements, and adding volatility indicators to stock selection criteria.
If even one of these is left out, it is highly likely that the familiar pattern of loss cases piling up immediately after launch will repeat itself.
Leverage is a double-edged sword. Used briefly, it amplifies gains; held too long, it eats away at assets. Korea’s market is releasing the sword before it has learned how to handle it. The meaning of legalization is not in simply letting it loose, but in preparing the means to wield it properly at the same time.
