South Korea’s benchmark Kospi index surged 15 percent in a volatile trading session, marking one of the most dramatic single-day moves in recent market history.

The sharp advance underscores the intensity of the ongoing bull market in Seoul, where investor sentiment has remained buoyant despite periodic turbulence.

The rally is largely driven by sustained strength in major semiconductor stocks, which have been the primary engine of the market’s upward trajectory.

According to Handelsavisen, the number of stock trading accounts in South Korea has reached an all-time high, reflecting deepening retail engagement with the equity market.

This surge in participation has amplified price movements, as domestic investors continue to pile into technology names.

The market’s performance has had tangible fiscal implications.
