The South Korean stock market reaches record high but uncertainty still exists.

The South Korean Composite Stock Price Index closed at 7490.05 on the 7th, once again hitting a record high. Yonhap News Agency reported on that day that the size of the South Korean stock market has surpassed Canada, rising to 7th place in the world. Yonhap News Agency cited statistics from Bloomberg that the total market value of listed companies in South Korea has increased by over 71% this year, reaching $4.59 trillion, surpassing the $4.5 trillion market size of the Canadian stock market. On April 27th, the size of the South Korean stock market surpassed $4 trillion for the first time, surpassing the UK to rise to 8th place in the world. Yonhap News Agency reported that driven by the "super cycle" of memory chips, the stock prices of Samsung Electronics and SK Hynix have performed strongly, with Samsung Electronics' market value surpassing $1 trillion. However, the rapid rise of the South Korean stock market has also raised concerns about structural risks in the market. Some Korean media analysts believe that the current high rise of the KOSPI is heavily reliant on the semiconductor sector, with the market value of Samsung Electronics and SK Hynix together accounting for over 40%. This means that if the memory chip boom slows down, investment expectations related to artificial intelligence cool off, or external geopolitical risks escalate, the South Korean stock market may face significant fluctuations. Kang Ha-kyu, director of the Korea-China Economic and Social Research Institute, believes that the stock market performance does not truly reflect the overall economic situation of South Korea. South Korea's actual GDP growth was only 1.0% last year, and aside from the semiconductor industry, there are still hidden concerns about long-term development momentum.
