Berkshire Hathaway
Q3 2025 • AI Analysis
Core Holdings & Strategic Adjustments
Apple (AAPL) remains Buffett's largest position, comprising 42.8% of the portfolio. Despite a modest 1.2% reduction this quarter, this reflects portfolio rebalancing rather than a change in fundamental outlook. Notably, Berkshire's cash reserves continue to climb, reaching a record $157 billion—this "ammunition" signals Buffett is patiently waiting for more attractive investment opportunities.
New Position Analysis
The most notable move this quarter is the continued accumulation of Occidental Petroleum (OXY), now at 8.7% of the portfolio. This reflects Buffett's conviction in traditional energy's long-term value...
MSFT
Microsoft CorporationQ3 2025 • AI Analysis
Ownership Overview: Institutional Consensus
Microsoft's institutional ownership structure exhibits a pronounced "high-end, core-focused" characteristic. Despite only 42 institutions holding positions during the review period, the total value reached approximately $34.8 billion, averaging nearly $830 million per institution—indicating Microsoft primarily attracts large, sophisticated institutional investors.
Institutional Moves: Divergence in Consensus
This quarter shows a clear "more selling than buying" pattern: 59.52% of institutions reduced positions while only 26.19% increased. However, this apparent bearishness requires deeper analysis. The Gates Foundation's massive reduction (-64.91%) reflects asset allocation adjustments rather than fundamental concerns...
Portfolio Health Score
AI Analysis
Overall Assessment
Your portfolio health score is B (72/100), placing you in the upper-middle tier. Your strength lies in Technology sector alignment with institutional consensus. However, there's notable concentration risk—your top 3 holdings exceed 65%, above the recommended 50% ceiling. The HHI concentration index of your portfolio is 0.18, indicating moderate concentration. While this isn't immediately concerning, diversification could help reduce volatility.
Optimization Recommendations
1. Reduce AAPL weight: Currently at 28.5%, consider trimming to below 20% 2. Add Healthcare exposure: Institutions are increasing this sector, but you have 0% allocation 3. Review TSLA position: Recent insider selling suggests caution These adjustments would bring your portfolio more in line with institutional consensus while maintaining your growth-oriented strategy.
