What is mutual fund portfolio overlap?

Portfolio overlap is the share of two funds' money that sits in the same stocks in the same amounts. Two flexi cap funds that both hold HDFC Bank, ICICI Bank and Reliance overlap by the smaller of their weights in each of those stocks.

How is portfolio overlap calculated?

For every stock both funds hold, take the smaller of the two weights, then add them up. If one fund holds HDFC Bank at 8% and the other at 5%, that stock adds 5% to the overlap. Only shares count; cash, bonds, deposits and REITs are left out. The figures use each fund's latest monthly portfolio disclosure.

Is high overlap between two funds bad?

Not by itself. RuDo studied 33,153 pairs of diversified equity funds over five years to September 2026. Funds from different fund houses with 50% to 70% overlap shared mostly the index's largest stocks, and holding both still made returns swing 12% to 15% less around the index than holding either one. Overlap above 70% came mostly from two funds of the same fund house, which hold nearly the same portfolio.

How often does the overlap change?

Fund houses disclose their portfolios every month, so the overlap is refreshed as each new disclosure arrives. It moves slowly for most diversified funds and faster for focused or high-turnover funds.
