Investing in mutual funds sounds like a smart move, right? But what if you invest in too many? Will it boost your returns through diversification or create unnecessary mutual fund overlap that drags your portfolio down?
Many investors believe that holding multiple top mutual funds minimizes risk. But here’s the catch—owning too many can lead to duplicate holdings, increased costs, and diluted returns. Striking the right balance is crucial, especially when choosing small cap stocks, index funds, or money market mutual funds.
So, how many funds should you really invest in? And what’s the best mutual fund to invest in for 2025? Let’s break it down and help you build a portfolio that truly works for you!
1. Understanding Mutual Fund Diversification
1.1 What is Diversification in Mutual Fund Investment?
When we talk about investing, the term “diversification” often comes up. But what does it really mean, especially in the context of mutual funds? Simply put, diversification is the strategy of spreading your investments across various financial instruments, industries, and other categories to reduce exposure to any single asset or risk. In mutual funds, this means investing in a mix of securities—like stocks, bonds, and other assets—to mitigate potential losses.
Imagine you’re at a buffet with a wide variety of dishes. Instead of piling your plate with just one item, you sample a bit of everything. This way, if one dish doesn’t suit your taste, you still have others to enjoy. Similarly, in mutual fund investment, diversification ensures that if one asset underperforms, the others can compensate, balancing the overall risk.
Mutual funds are inherently designed to provide diversification. For instance, an equity mutual fund might invest in a range of companies across different sectors—such as technology, healthcare, and consumer goods. This approach reduces the impact of a downturn in any single sector on your overall investment.
1.2 Why Investors Prefer Diversification
You might wonder, why is diversification so crucial? The primary reason is risk management. No matter how much research you do, predicting the exact performance of a particular stock or sector is challenging. Diversification acts as a safety net, ensuring that poor performance in one area doesn’t drastically affect your entire portfolio.
For example, let’s consider the period during the COVID-19 pandemic. While sectors like travel and hospitality suffered significant losses, technology and pharmaceutical sectors experienced growth. Investors with diversified mutual fund portfolios were better positioned to weather the storm, as gains in certain sectors offset losses in others.
Additionally, spreading investments across various assets helps maintain consistent returns in the long run. Instead of experiencing extreme highs and lows, a diversified mutual fund investment is more likely to provide moderate but consistent growth, aligning with long-term financial goals.
2. The Problem of Mutual Fund Overlap
2.1 What is Mutual Fund Overlap?
While diversification is beneficial, it’s essential to be cautious about mutual fund overlap. This occurs when multiple mutual funds in your portfolio hold similar or identical securities. At first glance, investing in several mutual funds might seem like a good diversification strategy. However, if these funds have overlapping holdings, you’re not truly diversified.
Think of it this way: if you buy multiple copies of the same book, you’re not expanding your library. Similarly, if your mutual funds invest in the same assets, you’re not effectively spreading your investment risk.

2.2 Risks of Investing in Too Many Mutual Funds
Investing in numerous mutual funds without proper analysis can lead to several issues:
- Dilution of Returns: Over-diversification can spread your investment too thin, leading to average returns. Instead of benefiting from the strong performance of a few well-chosen funds, your gains might be diluted across many funds.
- Increased Management Costs: Each mutual fund comes with its own set of fees and expenses. Holding multiple funds can increase your overall costs, eating into your returns.
- Complex Portfolio Management: Managing and tracking the performance of numerous funds can be cumbersome. It becomes challenging to maintain a cohesive investment strategy.
For instance, if you invest in five different large-cap mutual funds, there’s a high probability that they hold many of the same stocks. This overlap doesn’t provide additional diversification but does increase complexity and costs.
2.3 How to Identify Overlapping Holdings
Identifying mutual fund overlap is crucial for effective diversification. Here are some steps to help you assess overlaps in your portfolio:
- Analyze Mutual Fund Portfolio Reports: Regularly review the holdings of your mutual funds. Most fund houses provide detailed portfolio disclosures on their websites or in annual reports.
- Use Overlap Analysis Tools: Several online tools can help you identify overlapping holdings. For example, the Mutual Fund Portfolio Overlap Tool by AdvisorKhoj allows you to compare the portfolios of two mutual funds to see the extent of common holdings. Similarly, the Portfolio Overlap Tool by PrimeInvestor enables you to compare commonalities between two or three equity funds.
- Consult Financial Advisors: If you’re unsure about analyzing overlap, consider seeking advice from financial advisors. They can provide insights and recommendations tailored to your investment goals.
By proactively identifying and addressing mutual fund overlap, you can ensure that your portfolio remains truly diversified, aligning with your financial objectives.
3. Striking the Right Balance: Diversification vs. Overlap
3.1 How Many Mutual Funds Should You Invest In?
Determining the optimal number of mutual funds in your portfolio is a balancing act. While diversification is essential, over-diversification can lead to the issues we’ve discussed. So, how many mutual funds should you hold?
Financial experts often recommend holding between 5 to 10 mutual funds, depending on your investment goals and risk tolerance. This range allows for diversification across different asset classes and sectors without causing significant overlap.

For example, a well-structured portfolio might include:
- Large-Cap Funds: These funds invest in large, established companies and provide stability. Including one or two large-cap funds can offer a solid foundation.
- Mid-Cap and Small-Cap Funds: These funds invest in medium to small-sized companies, offering higher growth potential but with increased risk. Allocating a portion of your portfolio to mid-cap and small-cap funds can enhance returns, especially during bullish market phases.
- Index Funds: These funds track specific market indices, providing broad market exposure at a low cost. Including an index fund can add a passive investment component to your portfolio.
- Debt or Money Market Mutual Funds: These funds invest in fixed-income securities, offering stability and regular income. Allocating funds to debt or money market mutual funds can balance the equity portion of your portfolio.
Here’s a sample allocation for a moderate risk investor:
Fund Type | Allocation Percentage |
---|---|
Large-Cap Funds | 40% |
Mid-Cap and Small-Cap Funds | 20% |
Index Funds | 20% |
Debt or Money Market Funds | 20% |
This allocation provides diversification across various asset classes while minimizing the risk of overlap.
3.2 Choosing the Right Mutual Funds to Avoid Overlap
Selecting mutual funds with distinct investment strategies is crucial to avoid overlap. Refer to guidelines below to make informed choices:
- Diversify Across Fund Categories: Invest in funds from different categories, such as large-cap, mid-cap, small-cap, sectoral, and thematic funds. This approach ensures exposure to various segments of the market.
- Review Fund Holdings: Before investing, examine the top holdings of the mutual funds. Ensure that there’s minimal overlap between the funds you’re considering.
- Consider Fund Management Styles: Different fund managers have unique investment philosophies. Combining funds managed by different fund houses can provide varied exposure and reduce overlap.
For instance, if you’re investing in a large-cap fund, a mid-cap fund, and a sectoral fund focusing on technology, ensure that the large-cap and mid-cap funds don’t have significant holdings in the same technology companies as the sectoral fund.
By carefully selecting mutual funds with complementary investment strategies, you can achieve effective diversification without unnecessary overlap, aligning your portfolio with your financial goals.

- Fund Manager’s Expertise: An experienced fund manager with a solid track record can influence the fund’s performance positively.
- Assets Under Management (AUM): A substantial AUM indicates investor confidence but ensure it’s not too large to hinder flexibility.
