When is portfolio overlap acceptable in mutual funds? Experts explain when common stocks become a concentration risk
Mint 1 hr ago·29 Sept 2026, 1:43 am
Portfolio overlap occurs when two or more mutual funds hold the same stocks. While this is common, it can become a concern if the overlap is too high. This happens when investors hold multiple funds that invest in similar companies, effectively creating a concentrated bet on a specific sector or theme. This defeats the purpose of diversification, which is to spread risk across different assets.
For investors, this matters because it can mask true exposure. You might think you are diversified, but you could be heavily weighted in a few stocks. This increases risk if those stocks perform poorly. To manage this, investors should review their fund holdings and look for significant overlaps. Understanding this helps in building a truly diversified portfolio that aligns with their financial goals.
