Summary of Key Points
The South Korean stock market has recently experienced severe fluctuations due to retail investors' excessive use of leveraged ETFs (index funds that use debt to amplify returns), which triggered circuit breakers across the entire market for two consecutive days. Regulators have urgently introduced two rounds of stringent measures to limit leveraged trading, but the market still shows a downward trend. Even Samsung Electronics' profits increasing by 18 times in the second quarter failed to stop the stock market from declining, with the KOSPI index falling by 17% over three days. There is a clear disagreement among institutions regarding whether the deleveraging process is complete: JPMorgan Chase believes that the deleveraging of leveraged ETFs and hedge funds is largely finished, while HSBC believes that retail financing levels remain high, indicating that the deleveraging has not yet been completed.
Why Did the South Korean Stock Market Drop So Hard? – The Toll of Leveraged Speculation
The South Korean stock market had risen sharply earlier due to the AI boom and positive expectations for chip demand. Many retail investors used leveraged ETFs (which essentially allow them to borrow money to invest in funds, potentially doubling their profits or losses). However, when SK Hynix' performance fell short of expectations, investors began to doubt the sustainability of the AI trend, leading to a panic-driven sell-off. The "amplifying effect" of leveraged products exacerbated the decline: if you borrow 100,000 won to invest and the market drops by 10%, you lose 20,000 (your own 10,000 plus the borrowed 10,000). This led to a vicious cycle of further selling, eventually triggering multiple circuit breakers as the market dropped too much.
What Measures Did Regulators Take? – From Restricting Access to Limiting Trading Volumes
Regulators have escalated their measures in two rounds, with the goal of reducing retail investors' use of leverage:
1. First round on July 16:
- New leveraged ETFs were banned from being listed.
- Advertising for these products was prohibited.
- The required margin increased from 140,000 yuan to 420,000 yuan (only cash could be used; stocks could no longer be used as collateral).
- A minimum of 20 shares had to be purchased (previously, just one share was required).
- Investors were required to spend an additional hour learning about the risks associated with these products.
2. Second round on July 29:
- The proportion of leveraged ETFs in total investments was limited (for example, they could not exceed 10%).
- Trading fees were increased to discourage frequent trading.
- Lessons from Hong Kong's experience were applied to enable direct intervention in emergencies.
- The market was monitored 24/7.
Why Didn't Samsung's Strong Performance Save the Market? – The Power of Downward Momentum
Samsung Electronics' profits surged by 18% in the second quarter, which initially boosted the stock market, causing it to rise by 5%. However, this momentum was short-lived as follows:
- High pressure to liquidate leveraged positions: Many retail investors had bought Samsung stocks using leverage and were forced to sell when prices dropped, resulting in significant losses.
- Lack of market confidence: Multiple circuit breakers scared investors, who preferred to flee the market regardless of positive news.
- Negative impact from other chip companies: SK Hynix' poor performance (a 5.6% drop) dragged down the overall market.
Is Deleveraging Really Complete? – Disagreement Among Institutions
Two major investment banks have completely opposite views:
1. JPMorgan Chase (optimistic):
- The scale of leveraged ETFs has shrunk from 50 billion US dollars to 17 billion US dollars (only one-third remains).
- The ratio of long to short positions in hedge funds has decreased from 5.7 to 3.2, indicating 90% completion of deleveraging.
- Retail financing levels have not increased rapidly, suggesting that investors still have cash and unrealized profits, making the risks controllable.
2. HSBC (pessimistic):
- Retail financing has only decreased by 15%, remaining high.
- The reduction in leveraged ETFs is due to market declines, rather than active selling by retail investors.
- Investors may have switched to other leveraged products (such as margin trading), meaning the deleveraging process is far from over.
Lessons for Ordinary Investors
This incident highlights a simple truth: leverage is a double-edged sword:
- Avoid unfamiliar leveraged products: Leveraged ETFs can lead to rapid profits but also quick losses, and it's difficult for ordinary investors to manage these risks.
- Don't chase gains or panic when prices fall: South Korean retail investors fell victim to their enthusiasm for AI-related stocks.
- Diversify your investments: Don't put all your money into one asset, especially high-risk ones.
- Pay attention to regulatory signals: When regulators start restricting certain products, it indicates significant risks; move away from them immediately.
In summary, there are no guaranteed profits in the stock market, especially when using leverage. Always consider whether you can afford to lose twice as much as you invested.
