Plain-English Takeaways
Transform complex charts and data tables into clear, readable insights. AI distills institutional moves and market signals into actionable intelligence you can understand at a glance.
Berkshire Hathaway
Q3 2025 • AI Analysis
Core Holdings & Strategic Adjustments
AI turns the trend chart, sector mix, and holdings table into three plain takeaways: Apple (AAPL) is still the largest position at 42.8% of the portfolio; the 1.2% trim looks more like rebalancing than a change in the long-term thesis. Berkshire's cash reserves also climbed to $157 billion. That suggests the firm is not chasing prices and is waiting for a better buying window.
Opportunity to Watch
The move worth watching is the continued build in Occidental Petroleum (OXY), now 8.7% of the portfolio. AI reads this as a higher energy exposure that may reflect confidence in long-term traditional energy cash flows.
MSFT
Microsoft CorporationQ3 2025 • AI Analysis
Ownership Overview: Institutional Consensus
AI combines the ownership changes, holder scale, and flow table into one readable view: Microsoft's institutional ownership is high-end and core-focused. Only 42 institutions appear in this sample, but their total position value is about $34.8 billion, or nearly $830 million per institution. That points to large, sophisticated holders rather than short-term capital.
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 needs context. BlackRock's modest trim and Capital Group's new position point to allocation divergence among large managers, not a single-direction institutional exit...
Portfolio Health Score
AI Analysis
Overall Assessment
AI turns the holding weights, sector benchmark, and stock-level gaps into a readable diagnosis: your portfolio health score is B (72/100), placing it in the upper-middle tier. The strength is Technology sector alignment with institutional consensus. The main risk is concentration: your top 3 holdings exceed 65%, above the recommended 50% ceiling, which can make a few stocks drive most of your 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.

How does 13F Hub use SEC filing data?
13F Hub turns public regulatory disclosures into a research workflow, while keeping the limits of delayed filings visible.
What data does 13F Hub track?
The homepage highlights institutional holdings from SEC Form 13F filings, insider activity from public disclosures, and derived views that help compare institutions, stocks, and portfolio changes.
How should 13F data be interpreted?
13F filings are periodic disclosures, not real-time position reports. They can reveal institution-level patterns, but they may be delayed, amended, or incomplete for current trading decisions.
Which signals are covered?
13F Hub focuses on institutional portfolio changes, stock-level ownership structure, insider disclosure signals, ratings context, and AI-assisted summaries for research and education.
Primary public sources
13F Hub is built for research and education. It does not provide personalized investment, tax, legal, or financial advice, and public filings should be checked against original SEC records before making decisions.
