South Korea's tech-heavy Kospi stock market has seen sharp market swings, driven by a frenzy around artificial intelligence. Many investors have lost significant amounts of money, with some facing margin calls and others feeling the pain of a 'gut-wrenching' slump.
Imagine you put all your money into a special kind of stock that's really popular, like a new video game. But then the game's popularity suddenly drops, and the stock's value goes down. That's what happened to many investors in South Korea's tech-heavy stock market. They lost a lot of money because the stocks they invested in were too volatile.
Analysis
Market Volatility in South Korea's Kospi Index
The Kospi, South Korea's tech-heavy stock market index, has seen one of the sharpest corrections in its history between June and August. This correction is comparable to the drops seen during the Covid-19 pandemic and the 1997 Asian financial crisis. The index more than doubled its value since the start of the year to rise above 9,000 points in mid-June, before plunging to 5,500 within a few weeks. It has now recovered some ground to about 6,800 points.
Concerns Over AI-Related Stocks
The slump in the Kospi has had a big impact on many of the country's personal investors who bought tech stocks over the past year. For Woongsa Kim, a look at his shares trading app is a painful reminder of what he had made then lost by investing in the South Korean stock market. At the start of the year, he used about half of a bonus from work to buy shares in tech giant SK Hynix. The stock quadrupled in value before most of those gains were wiped out, leaving his investment, now worth about 300 million won, at roughly half the value of its peak.
Leveraging and Margin Calls
The sell-off came after tech shares had soared for months, 'generating the extreme euphoria' that has moved some personal investors to take out loans to invest. Leveraging lets an investor control a larger number of stocks than their own cash would otherwise allow, which delivers a bigger profit if the shares rise. However, if the stocks fall past an agreed level it can trigger what is known as a margin call - when a broker demands payment of the debt. By the end of July an estimated 1.2 million South Korean personal investor accounts had faced margin calls, equivalent to about one in every 30 working-age adults in the country.
Key points
- South Korea's tech-heavy Kospi stock market has seen sharp market swings, driven by a frenzy around artificial intelligence.
- Many investors have lost significant amounts of money, with some facing margin calls and others feeling the pain of a 'gut-wrenching' slump.
- The wild swings in the Korean stock market are raising concerns about other markets around the world, particularly those with a high concentration of tech stocks.
If the Korean stock market stabilizes and the value of tech stocks rises again, many investors who lost money may be able to recover their losses. However, this is uncertain and depends on various market factors.
If the Korean stock market continues to be volatile and the value of tech stocks falls further, many investors may face significant financial losses. This could have a ripple effect on other markets around the world.
