Mirae Asset Global Investments Co., Ltd.

Mirae Asset Global Investments' Q1 2026 13F is among the most unusual in the large-filer universe: a single Berkshire Hathaway Class A position accounts for 88.4% of the reported $299.3B book, which itself ballooned from $36.0B the prior quarter. Outside that dominant stake, the portfolio holds only a thin diversified tail — Nvidia (0.87%), Apple (0.64%), Alphabet (0.59%), and Microsoft (0.48%). New positions this quarter include Berkshire Class A itself, Walmart, ConocoPhillips, Procter & Gamble, Exxon Mobil, and UnitedHealth; Alphabet C shares and a QQQ mini ETF were among exits.
