Data Pipeline Overview

Official AMC Website Disclosures (SEBI-mandated)
Excel / PDF portfolio statements
Monthly disclosures, some AMCs publish weekly
Our catalog includes AMCs awaiting eligible equity or hybrid funds. These AMCs remain selectable, with a clear availability message. Catalog membership does not confirm complete data for every scheme or month. History starts below are shown where documented in the catalog; use the dashboard’s available-period filters to check a specific scheme. Fund types are examples, not a complete scheme inventory.
AMC Coverage & Monitoring
Note: We continuously monitor and add new AMCs. Coverage expansion is announced in our changelog. All data is sourced directly from official AMC websites and SEBI-mandated disclosures.
Excluded Fund Types
The following fund categories are intentionally excluded from our analytics pipeline. These are typically debt-oriented or passive strategies that do not represent active stock selection by fund managers.
Exclusions are enforced automatically during data ingestion. If an AMC's disclosure contains both equity and debt funds, only the equity/hybrid portion is retained.
Data Quality Checks
ISIN Validation
Holdings must match the 12-character ISIN format: two letters, nine letters or digits, and a final digit. This format check rejects date strings and internal codes; it does not certify an ISIN check digit.
Quantity & Value Checks
Quantity and Market Value must both be strictly positive (> 0). Zero or negative values are treated as data errors and discarded.
Deduplication
Files are tracked by filename and timestamp. Already-processed files are skipped automatically unless a force-reprocess flag is set.
Scheme Normalization
Scheme names are normalized to UPPER CASE and scheme alias mappings handle renamed funds (e.g., "Formerly known as...").
Month Standardization
All month fields are converted to full English month names (e.g., "Nov" → "November") to ensure consistent time-series comparisons.
Grand Total Exclusion
Summary and "Grand Total" rows from AMC Excel files are automatically excluded to prevent inflated holdings counts.
