Summary
South Korea's KOSDAQ index surged approximately 6% to reclaim the 1,000 level for the first time in four years, marking a significant recovery for the country's secondary stock exchange. This advance occurred as part of a broader rally across South Korean equity markets, with KOSDAQ gaining 21.52 points (2.04%) in a single session to close at 1,077.86. The secondary exchange's performance reflects renewed institutional and retail interest in mid-cap and small-cap equities that comprise the bulk of KOSDAQ's constituent companies.

The strength in KOSDAQ coincided with record-breaking performance across South Korea's broader equity ecosystem. The combined market capitalization of KOSPI and KOSDAQ exceeded $4.1 trillion (₩6,100 trillion) for the first time in history, as the KOSPI benchmark index reached an all-time high and completed its sixth consecutive day of gains. KOSPI surged past 6,300, with intraday highs touching 6,313.27, underscoring robust buying momentum across large-cap and small-cap segments simultaneously.

Market analysts attribute KOSDAQ's acceleration to growing expectations surrounding government-backed public investment fund initiatives specifically targeting small and medium enterprises. These policy announcements have provided a supportive backdrop for secondary market constituents, which represent a critical segment of South Korea's entrepreneurial and innovation-driven economy. Individual investors maintained net buying positions in the KOSDAQ market, contributing meaningful demand to the rally.

The secondary exchange's advance came after South Korea's equity markets experienced earlier volatility but recovered sharply by week's end. KOSPI surged over 8% in Friday trading before paring to a 4.6% gain, following positive international sentiment and recognition of South Korea's growing artificial intelligence sector capabilities. The combined resilience of both primary and secondary exchanges reflects the structural strength of South Korean capital markets and investor appetite for exposure across the country's corporate spectrum, from large conglomerates to emerging growth companies.
