Samjeonniks Leverage
Overview
Samjeonniks Leverage refers to an investment strategy that aims to maximize returns through leverage (borrowing/derivatives) by utilizing the stock price volatility of Samsung Electronics and SK Hynix (collectively referred to as 'Samjeonniks'). This is a high-risk, high-return approach that became a trend among individual investors in the domestic stock market, primarily executed through leveraged ETFs (exchange-traded funds), margin trading, and futures/options. It gained attention in the early 2020s amid expectations of a semiconductor supercycle, but caused significant losses and controversy due to the semiconductor industry downturn in 2022–2023.

Concept and Types of Leverage
Leverage means 'a lever' and is a financial technique that enables large-scale investments with small capital. The main methods used in Samjeonniks Leverage are as follows:
- Leveraged ETFs: ETFs such as KODEX Leverage and TIGER Leverage that track Samsung Electronics and SK Hynix as underlying assets, offering twice the daily return. For example, if the underlying index rises by 1%, the ETF rises by 2%, but if it falls by 1%, the ETF falls by 2%.
- Margin Trading: A method of borrowing funds from a securities company to buy stocks, which multiplies profits when stock prices rise but increases principal loss and interest burden when they fall.
- Futures and Options: Leveraged investments using stock index futures (KOSPI200) or individual stock options, requiring management of high volatility and expiration dates.
Background of the Rise of Samjeonniks Leverage
During the liquidity-driven market following the COVID-19 pandemic in 2020, semiconductor stocks surged, leading to a massive influx of individual investors into leveraged ETFs. In particular, in 2021, Samsung Electronics' stock price broke through the 90,000 won range, becoming a symbol of the 'Donghak Ant Movement,' and SK Hynix also rose on expectations of AI semiconductor demand. During this period, 'Samjeonniks Leverage' became synonymous with 'debt investment' (borrowing to invest) in online communities.
Risks and Examples
Leveraged investments are particularly risky in the volatile semiconductor sector. In 2022, due to global interest rate hikes and slowing semiconductor demand, Samsung Electronics' stock price fell to the 50,000 won range, causing holders of leveraged ETFs to lose more than 50% of their principal. A representative example is the 60% crash in the net asset value (NAV) of the KODEX Leverage ETF within a year in September 2022. Additionally, investors who bought on margin faced the risk of forced liquidation (margin calls), incurring further losses.
Investment Strategies and Limitations
Some experts advise using leverage only for short-term trading. For example, buying and selling leveraged ETFs within 1–2 days immediately after positive semiconductor industry news. However, long-term holding leads to a problem called 'volatility decay,' where returns are lower than the underlying index's gains. For instance, if the index rises by 10% and then falls by 10%, a leveraged ETF would record a 4% loss.
Recent Trends
As of 2024–2025, the fervor for Samjeonniks Leverage investment has somewhat subsided but still attracts attention. In the second half of 2024, due to a surge in AI semiconductor demand, SK Hynix's stock price broke through 200,000 won, and leveraged ETF returns exceeded 50% for a period. However, in early 2025, volatility increased again due to uncertainties in U.S. tariff policies and concerns over a semiconductor industry adjustment. Financial authorities maintain the current leverage multiplier limit (2x) for leveraged ETFs to protect individual investors and are considering reducing margin trading limits. Recently, interest in overseas-listed 3x leveraged ETFs (e.g., SOXL) has grown, and domestic investors' overseas leveraged investments are also on the rise.
