The fund cut its Information Technology sector overweight slightly but reduced exposure broadly, all while loading into BRK-A.
Mirae Asset's 2026-Q1 filing documents a near-total portfolio transformation into a single stock. The turnover ratio of 1.64 and the HHI jump from 0.02 to 0.78 highlight the scale of the restructuring. Price volatility caused divergences between trading actions and value changes in several major holdings. The fund now holds extreme concentration risk with BRK-A comprising 88.40% of assets.
