Seohak Ant (Seohak Gaemi)
Overview
Seohak Ant is a neologism referring to domestic individual investors who invest in overseas stock markets, particularly the U.S. stock market. It is a compound word combining 'Seo (西)' from 'Western learning' and 'Ant investor (Gaemi tujaja).' This phenomenon surged after the COVID-19 pandemic in 2020, driven by increased volatility in the domestic stock market and growing interest in global blue-chip companies. These investors primarily focus on U.S. technology stocks, growth stocks, and ETFs. With the development of platforms enabling global diversification even with small amounts, it has drawn attention as a contrast to the 'Donghak Ant' movement in the Korean stock market.

Background and Growth
The Seohak Ant phenomenon began in earnest in 2020. At that time, the domestic KOSPI index experienced repeated sharp fluctuations, increasing uncertainty, while the U.S. stock market saw notable growth in global representative companies such as Apple, Tesla, and NVIDIA. Additionally, domestic securities firms lowered fees for overseas stock trading and made access easy through mobile trading systems (MTS), leading to an explosive increase in individual investors' holdings of overseas stocks. According to the Korea Securities Depository, the overseas stock custody amount of domestic investors, which was about $30 billion at the end of 2020, exceeded $100 billion by the end of 2024.
Investment Tendencies and Characteristics
Seohak Ants tend to focus on growth stocks and technology stocks. Representative stocks consistently among the top net purchases include Tesla, NVIDIA, Apple, Microsoft, and Amazon. While many aim for short-term profit-taking rather than long-term investment, 'dollar-cost averaging' strategies involving regular small investments have also become common. Furthermore, Seohak Ants are active in information gathering, sharing and analyzing real-time information through overseas stock-related communities (e.g., Naver Cafes, DC Inside Stock Gallery, YouTube channels).
Main Investment Vehicles
The main investment vehicles for Seohak Ants are U.S.-listed ETFs (exchange-traded funds) and individual stocks. Representative ETFs include SPY and VOO tracking the S&P 500, QQQ tracking the Nasdaq 100, as well as individual stocks like Tesla and NVIDIA. Recently, more investors have adopted high-risk, high-return strategies using leveraged ETFs (e.g., TQQQ, SOXL) or inverse ETFs. Trading is conducted through overseas stock-specific accounts at securities firms that offer overseas stock trading (e.g., Mirae Asset Securities, Kiwoom Securities, Samsung Securities).
Risks and Challenges
Seohak Ants face additional risks such as exchange rate fluctuations, time differences, and taxes. Capital gains tax (22% on amounts exceeding 2.5 million won annually) and dividend income tax (15.4%) from overseas stock investments are key considerations. They are also directly exposed to U.S. stock market volatility (e.g., interest rate hikes, recession fears), and portfolios centered on technology stocks, which are highly sensitive to interest rates, carry significant loss risks. For instance, when the Nasdaq index fell over 30% due to the Federal Reserve's rapid interest rate hikes in 2022, Seohak Ants' valuation losses also surged.
Latest Trends
Since 2024, Seohak Ants have become more sophisticated. From late 2024 to early 2025, investments in AI semiconductor stocks, particularly NVIDIA, surged, with a notable concentration on the 'Big Tech 7': Apple, Microsoft, Google, Amazon, NVIDIA, Meta, and Tesla. Additionally, intensified competition among overseas stock trading platforms has driven fees to near zero, and fractional share trading has become common, allowing investments in high-priced stocks (e.g., Berkshire Hathaway A shares) with amounts under 10,000 won. Recently, a 'Seohak Ant 2.0' phenomenon has emerged, expanding investment scope to non-U.S. overseas stocks such as those from Japan, China, and India. However, as of 2025, with increased volatility due to U.S. tariff policies and geopolitical risks (Taiwan Strait, Middle East), the importance of diversification and risk management is being reemphasized among Seohak Ants.
