Where is every fund house overweight?

Each AMC's top-50 equity holdings are taken from its most recent monthly portfolio disclosure (AMFI mandate), mapped to ISINs and matched against the Morningstar sector taxonomy via the NSE/BSE symbol bridge. The % of AMC equitycolumn is the stock's aggregate weight across every equity scheme that AMC runs — not just one fund.

The Gini coefficient is computed across the same top-50 universe. An AMC that splits its book evenly across 50 names sits near 0.40; one that runs concentrated 10-position portfolios pushes past 0.75. Used here as a single-number book-shape summary, not as a quality signal — concentration can be a feature (high-conviction house) or a risk (single-stock blow-ups hit harder).

Sector cells in the heatmap sum the top-50 stocks in that sector for each AMC. Cells with no top-50 exposure are blank, not zero — the AMC may still hold the sector outside its top-50.
