Mutual Fund Overlap Checker

How this is calculated

Figures describe disclosed portfolios. They are not a rating and not a suggestion to buy, sell, or drop a fund.

1. Pairwise overlap

   $$\sum_{c}\min(w_{A,c},\,w_{B,c})$$

   A company at 7% in one fund and 5% in the other contributes 5 percentage points.

2. Combined holding weight

   $$\sum_{f}(a_{f}\times w_{f,c})$$

   Equal allocation gives every fund the same weight, and investment amounts are used only when every fund has one.

3. Unique exposure

   $$\sum_{c\in\mathrm{only}(f)} w_{f,c}$$

   Unique exposure is the weight a fund has in companies none of the other selected funds hold.

4. Removal similarity

   $$\sum_{c}\min(w_{c},\,w'_{c})$$

   Includes cash and other assets as one residual bucket, and 100% means the underlying mix is unchanged.

Direct and Regular plans, and Growth and IDCW options, are one scheme portfolio. Weights are taken from the latest month every selected fund has filed. Cash, derivatives and unmapped lines stay in the data-quality note and are not forced to 100.
