Mirae Asset Stake Drops Below 10% to 9.83% After ETF Redemptions and Lending — DB HiTek

Summary

Mirae Asset Global Investments reported a 1.19 percentage point decrease in its stake, falling from 11.02% (4,796,002 shares) to 9.83% (4,276,882 shares) as of June 2, 2026. The 519,120-share reduction was driven primarily by ETF redemptions, securities lending, and routine market trading between May 28 and June 2. The crossing below the 10% major shareholder threshold is the key regulatory event, though much of the movement reflects passive fund operations rather than active conviction selling. Trading prices ranged from approximately KRW 181,400 to KRW 220,500 across the reporting period.
