Investment Commentary

Massachusetts Financial Services employs an active, very low turnover growth strategy, with a portfolio of nearly 4,000 positions totaling $297.5 billion in AUM. The top five holdings—NVIDIA, Microsoft, Apple, Alphabet, and Amazon—represent 14.6% of assets, anchored by a 19.6% allocation to technology and a 15.1% weight in financial services. This concentrated exposure to mega-cap tech leaders, combined with diversification across 15 sectors and over 3,900 names, reflects a conviction-driven approach that balances high-conviction bets with broad market coverage to manage risk. The inclusion of JPMorgan, Johnson & Johnson, and Exxon Mobil further indicates a willingness to hold defensive and cyclical value staples within a core growth framework.
