Circuit breakers have become commonplace in the South Korean stock market, with high volatility attracting retail investors, turning trading in South Korean stocks into a "squid game."

According to Mars Finance, on July 7th, the Wall Street Journal published an article analyzing the recent high volatility of the South Korean stock market. The article cited data showing that in the past year, the South Korean KOSPI index fluctuated by more than 2% on 77 separate days. During the same period, the S&P 500 index in the US experienced only five such instances. The KOSPI fluctuated by more than 3% on 44 days, while the S&P 500 never exceeded 3%, and the KOSPI fluctuated by more than 5% on 23 days. The report stated that this volatility has become one of the factors attracting many South Korean retail investors who trade purely for the sake of trading. Maxence Visseau, founder of macro and quantitative hedge fund Arkevium Capital, commented, "Volatility is the key attraction for retail investors seeking excitement." The report also noted that foreign capital outflows exceeded $100 billion (approximately 154 trillion won) in the first half of this year, with $30 billion flowing out in June alone. This trend "could ultimately harm local investors."
