Example: If Fund A holds 5% in ICICI Bank and Fund B holds 6%, the overlap contribution from that stock is 5% (the minimum of the two). We sum this for all common shares to get the total weighted overlap.
Here is a pre-rendered example showing a typical comparison. The funds have a weighted overlap of <strong>27.02%</strong>.
Weighted Overlap
| Stock | Min. Weight |
|---|---|
| ICICI Bank | 5.21% |
| Infosys | 4.67% |
| Axis Bank | 2.34% |
| Bharti Airtel | 3.12% |
| State Bank of India | 2.98% |
- Low (0-15%): Good diversification. The funds have distinct strategies.
- Moderate (15-30%): Common for funds in the same category (e.g., large-cap). Review to ensure you are comfortable with the shared exposure.
- High (30-50%): Significant overlap. You may be paying two sets of fees for the same stocks. Consider consolidating.
- Very High (>50%): The funds are practically clones. Replacing one to improve diversification is highly recommended.

Data & Methodology
Data Sources: Our holdings data is sourced from publicly available scheme documents and updated periodically. While we strive for accuracy, we cannot guarantee it. Always verify with official AMC factsheets. Last Updated: Aug 2025.
Matching Logic: Holdings are matched first by their stock ticker (e.g., 'RELIANCE'). If a ticker is not available, we use a normalized company name (e.g., 'reliance industries' after removing 'Ltd', 'Inc', etc.). Non-equity holdings like 'Cash', 'Tri-party repo', or 'Net Receivables' are excluded from the calculation based on a regex match for common terms.
