Summary of Key Points
Recently, South Korea has experienced a nationwide stock market frenzy driven by the soaring prices of semiconductor stocks from Samsung Electronics and SK Hynix. People of all ages, from students to the elderly, have flocked to the markets, with some using leverage, withdrawing from insurance policies, and using rental deposits to invest in stocks. This surge is fueled by the "super cycle" in semiconductors brought about by AI, but it comes with risks such as high leverage, potential market reversals, and the withdrawal of foreign capital. It has also profoundly changed Korean societal attitudes—for example, the hierarchy of professions has been reversed, with jobs at Hynix now considered more prestigious than those of doctors, and Samsung employees even have to pretend to work at Hynix when looking for a partner.
1. National Mania: From Students to the Elderly, No One Wants to Be "Suddenly Poor"
What South Koreans fear most nowadays is not unemployment, but not owning stocks in Samsung or Hynix—this state of "relative poverty" is referred to as being "suddenly poor." Almost everyone, from young people to the elderly, has jumped into the stock market:
- Young people are rushing to open accounts: In the first quarter of 2026, the number of new accounts opened by individuals under 18 increased by tenfold, and there were 344,000 minors among Samsung's shareholders. 81% of young people in their early 20s are trading stocks, which is 13 times higher than the same age group in their parents' generation.
- The elderly are more willing to take risks: Investors over 50 years old account for 62% of the total amount borrowed from securities firms to trade stocks. The leverage balance of those over 60 years old has increased by 2.7 times in one year; some have even withdrawn from life insurance policies (worth 4.9 trillion won) to invest in the stock market.
- Staring at screens has become the norm: Office workers crowd company restrooms to monitor market trends, university classrooms have turned into investment forums, and even esports players can't help but switch to their screens during broadcasts to check stock prices. Even celebrities have shared stories of earning 4,500% in profits from their investments.
The most extreme case involved a person in prison who used a 260 million won rental deposit to buy transformer stocks. After being released, they made a 402-fold profit, turning 260 million won into 105.2 billion won—a story that has inspired many others to enter the market with hopeful eyes.
2. The Semiconductor Super Cycle: The Wealth Engine driven by AI
The core of this stock market boom is the explosive demand for memory driven by AI:
- Samsung and Hynix dominate the gains: These two chip giants account for 40% of the Korean Composite Index's weight and have seen year-on-year increases of 200% and 250%, respectively, contributing significantly to the index's rise. Their market values have both exceeded one trillion dollars, pushing South Korea's stock market total value above 5 trillion dollars, ranking it sixth in the world.
- Employee benefits: Hynix employees are set to receive an average bonus of 660,000 to 690,000 yuan in 2025, which may rise to 6.1 million yuan by 2027. Although Samsung's bonus is only 2.35 million yuan, it has led to significant spending among its employees—real estate prices in areas near their commuting routes have skyrocketed, and Ferrari dealerships are flooded with orders from these employees.
- The dual nature of the cycle: Despite the current surge, Hynix suffered a huge loss of 9.1 trillion won in 2023, and Samsung's net profit was the worst in 12 years. The semiconductor industry follows a cycle of "expansion → oversupply → loss → reduction → recovery." This so-called "super cycle" is supported by AI demand, but once the AI boom fades, risks will emerge.
3. Major Shifts in Social Attitudes: Reversal of Professional Hierarchy, Changes in Dating Practices
This wave of wealth creation has completely transformed Korean perceptions:
- Reversed professional hierarchy: The traditional preference for medical schools has been overturned, with the term "Hynix-Med-Dent-Korea" (referring to SK Hynix, doctors, and dentists) now placing Hynix employees above doctors. Even college students with no knowledge of semiconductors are competing for jobs at Hynix.
- Changes in dating practices: Samsung employees used to be highly sought after, but now Hynix employees are even more desirable. During dating, people pretend to work at Hynix first and only reveal their actual job when they've established the other person's character; a Hynix-related item is considered more valuable than a house title.
- Contradictions in fertility views: While the wealth boom could increase birth rates, semiconductor employees are hesitant to take maternity leave due to performance-based bonuses and attendance requirements. Married couples are preferring to delay having children.
4. Hidden Concerns Behind the Carnival: Leverage, Capital Flight, and Cycle Risks
Behind the excitement, South Korea's stock market faces three major risks:
- High leverage: The total amount borrowed from securities firms has reached 36 trillion won (about 162.5 billion yuan), a 20-year high. Some individual investors are using leverage of up to 1.7 billion won to bet heavily on Hynix stocks, and several firms have temporarily suspended new loans. A drop in stock prices could instantly turn these investors into the poor.
- Capital flight: In the first 20 days of May, foreign investors sold 14.7 trillion won worth of Samsung stocks, while individual investors with leverage took over 11.4 trillion won worth of shares. Is this a buying opportunity or just catching a falling knife? No one is sure.
- Government's role in the risk: Although the finance minister expressed concerns about high leverage, the South Korean exchange approved 18 leveraged ETFs related to Samsung/Hynix and plans to extend trading hours to 12 hours (to facilitate trading for office workers), effectively handing out more chips to the gamblers.
South Korea is like someone on a rocket, shouting "We'll always need more memory" while fearing the rocket might overheat and explode. No one knows when to get off.
In Conclusion
This nationwide stock market craze in South Korea is a wealth-driven frenzy fueled by AI, but it's also a huge gamble. A win can bring tremendous gains, but a loss could return people to the starting point of "suddenly poor." For ordinary people, it's best to watch from the sidelines and avoid taking on excessive leverage. After all, the cycle of the market is merciless.
