Taiwan and South Korea have surged in global stock market rankings, overtaking Canada and the UK to become the sixth and eighth largest markets, respectively. This shift is driven by the AI boom, which has concentrated capital in semiconductor firms like TSMC in Taiwan and Samsung Electronics and SK Hynix in South Korea, making these markets heavily dependent on a few AI-linked companies. While this growth highlights the importance of the semiconductor supply chain, it also raises concerns about concentration risk and potential market volatility, as seen in recent stock fluctuations. Investors should watch for how these dynamics evolve amid labor issues and global demand shifts.
