First, Look at the Trend: From "Everyone Trading Crypto" to "Everyone Trading Stocks"
From 2017 to 2021, South Korea was one of the most crypto-crazed markets globally. At the time, local prices were consistently higher than overseas prices, a gap known as the "Kimchi premium" — essentially meaning "Koreans wanted to buy so badly that local demand was too strong."
In recent years, the tide has turned: after tighter regulations and a crypto cooldown, a large number of Korean retail investors have shifted their battlefield to U.S. stocks. They have a specific nickname: "Seohak Ants" (서학개미) — swarming to buy U.S. tech stocks and leveraged ETFs (like triple-leveraged Nasdaq products). Korean retail investors were once among the largest holders of certain global leveraged ETFs.
Why Such a Love for High Leverage and High Risk? 5 Structural Reasons
This isn't a matter of "personality," but the result of several real-world forces combining:
1. Sky-High Housing Prices + Rigid Social Hierarchy → "Saving Slowly Is Useless"
Seoul's housing prices are so high that it's nearly impossible for the average salaried worker to catch up through wages alone. Korean society also has the concept of "Gold Spoon / Dirt Spoon" (금수저 / 흙수저), describing how one's birth determines their starting point. When young people feel that the path of "saving normally, buying a house, and changing your destiny" is blocked, they naturally become more receptive to a "한탕" (one big gamble) mentality — high leverage and high risk offer the illusion of "betting small to win big and turning things around in one shot."
3. Limited Local Channels → Capital Spillover
The domestic Korean stock market has significant restrictions on leverage and short selling for retail investors, limiting the high-volatility instruments available. Consequently, capital naturally flows towards places with "low barriers and high volatility":
- Initially, it was crypto — 24/7, globally liquid, with access to high-leverage contracts.
- Now, it's U.S. stocks + leveraged ETFs — through brokers, investors can buy triple-leveraged Nasdaq ETFs, single tech stock options, and other high-volatility tools.
4. Strong Community, Strong Herd Mentality
South Korea has an extremely strong social and community culture (KakaoTalk groups, various "stock/crypto chat rooms", influencers, and YouTube investment bloggers). A single success story can amplify rapidly within a community, creating a FOMO (Fear Of Missing Out) effect of "everyone is buying, I'll miss out if I don't." This highly synchronized herd behavior makes both buying and selling more extreme, amplifying volatility.
5. Currency and Future Uncertainty
When the Korean won weakens against the U.S. dollar, holding dollar-denominated assets (U.S. stocks) itself offers "hedging + currency gains" appeal. Combined with long-term concerns about an aging population, pensions, and employment, young people are more inclined to "gamble for a future now." This is a macroeconomic backdrop for the capital shift from local markets to U.S. stocks.
Why Is "Everyone Doing X" Often a Risk Signal?
Whether it's "everyone trading crypto" or "everyone trading stocks," when a trade becomes a mass movement discussed on every street corner, it often means:
- Potential new buyers are running low: Most capital that could enter has already entered, making the market more dependent on "the next higher-priced buyer."
- Leverage has accumulated to high levels: When everyone is leveraged, a downturn can trigger cascading liquidations, amplifying the decline.
- Emotion replaces fundamentals: Prices are driven by FOMO, not by the underlying value of the asset.
This doesn't mean a crash happens the day after "everyone participates," but rather: The more crowded it gets, the more cautious you should be, and the less you should chase highs with leverage.
The "Hidden Trap" of Leveraged ETFs: Volatility Decay
Many Korean retail investors heavily hold "triple-long" leveraged ETFs, which have a characteristic often overlooked by beginners — volatility decay: They track "3 times the daily return," not "3 times the total return over a period." In a choppy, sideways market, even if the index ends up flat, a triple-leveraged ETF can steadily decline.
What Can Beginners Learn from This? (The Most Important Part)
- ✓ Understand where the "preference" comes from: The appeal of high leverage is the illusion of "betting small to win big," but leverage also amplifies losses and can be wiped out entirely by liquidation.
- ✓ Don't use "massive public interest" as a reason to buy: The more everyone is talking about an asset, the more you should be wary of being the last one holding the bag.
- ✓ Learn to survive first: Only use disposable income, set stop-losses, control your position size, and stay away from high-leverage tools you don't understand.
- ✓ Distinguish between "investing" and "gambling": Long-term growth comes from diversification and time, not from a single all-in leveraged bet.
Summary
The shift of Korean retail investors from "everyone trading crypto" to "everyone trading stocks" is driven by structural forces like high housing prices, a rigid social hierarchy, low interest rates, limited local channels, and a strong community culture, fostering a preference for high leverage and high volatility. The target has changed (crypto → U.S. stocks/leveraged ETFs), but the "strike it rich in one go" mentality remains. For the average person, the real lesson isn't "how to gamble like a Korean," but to understand the cost of this preference, avoid the traps of high leverage, and manage risk first.
