Frequently Asked Questions
What is mutual fund portfolio overlap?
Portfolio overlap is the percentage of common stocks held by two mutual fund schemes, weighted by how much of each fund's portfolio they represent. A high overlap means the two funds are effectively holding a similar basket of stocks, even if their names or categories differ.
How is mutual fund overlap calculated?
For every stock held by both funds, we take the smaller of the two portfolio weights and add these up across all common holdings. This gives a single overlap percentage — the share of the portfolio that is effectively duplicated if you invest in both funds.
Why does portfolio overlap matter?
If you hold two funds with high overlap, you are not getting as much diversification as you might think — a large part of your money is riding on the same set of stocks through two different schemes. Checking overlap before adding a new fund to your portfolio helps you avoid unnecessary duplication.
What is considered a high mutual fund overlap?
There is no fixed rule, but as a general guide: overlap below 30% is considered low (the funds are meaningfully different), 30–60% is moderate, and above 60% is considered high — at that point, holding both funds adds limited extra diversification.
How do I use this mutual fund overlap calculator?
Search and select any two mutual fund schemes in the boxes above. Once both are selected, we automatically calculate and display the % of common holdings, the list of shared stocks, and a side-by-side comparison of key metrics like AUM, expense ratio and returns.
