Mirae Asset Stake Rises to 10.57% on ETF Creation/Redemption Activity — DB HiTek

Summary

Mirae Asset Global Investments reported its ownership of DB HiTek common shares increased from 9.92% to 10.57% (4,599,432 shares) as of May 13, 2026, crossing the 10% major shareholder threshold. The 283,027-share net increase was driven primarily by ETF creation and redemption flows, along with stock lending returns and modest market buying/selling around the 152,000-189,000 won range. Crossing the 10% line triggers stricter disclosure obligations under Korean rules, requiring more frequent reporting of any future trades. The activity reflects index/ETF mechanical flows rather than an active conviction build by the asset manager.
