Investing in 8-10 Mutual Funds? Here's Why Too Many SIPs Could Hurt Your Portfolio Returns

Mutual Funds Investment Strategy: Many investors believe that adding more mutual funds to their portfolio automatically increases diversification and improves returns. However, financial experts warn that holding too many SIPs can create overlap, complicate portfolio management, and even reduce overall performance. Here's why investors should think carefully before adding another mutual fund to their investment basket.

More SIPs Don't Always Mean Better Returns

The popularity of mutual funds continues to grow as investors increasingly turn to Systematic Investment Plans (SIPs) for long-term wealth creation.

The journey often starts with a single equity fund. Later, investors may add an ELSS fund for tax-saving benefits, followed by a mid-cap or small-cap fund in pursuit of higher returns. Over time, this habit can lead to a portfolio containing eight, ten, or even a dozen mutual funds.

While this may appear well-diversified on the surface, experts say the reality is often quite different.

The Hidden Problem of Fund Overlap

One of the biggest mistakes investors make is starting new SIPs without evaluating their existing portfolio.

Many mutual funds, especially within the same category, invest in similar stocks. As a result, investors may end up holding multiple funds that essentially own the same companies.

For example, two different large-cap funds may have significant exposure to the same blue-chip stocks. In such cases, adding more funds does not increase diversification—it simply creates duplication.

This overlap can dilute the effectiveness of portfolio construction and make tracking investments more difficult.

Diversification Is About Quality, Not Quantity

Financial planners emphasize that true diversification does not come from owning a large number of mutual funds. Instead, it comes from investing across different asset classes, market capitalizations, sectors, and investment strategies.

The common belief that more funds automatically generate higher returns is a misconception.

Returns are driven by selecting the right funds that complement each other, not by accumulating as many schemes as possible.

A carefully designed portfolio with a few well-chosen funds can often outperform a cluttered portfolio filled with overlapping investments.

Too Many Funds Can Make Portfolio Management Difficult

There is no fixed formula that determines the ideal number of mutual funds an investor should hold. The right number depends on factors such as investment goals, risk tolerance, and monthly contribution amounts.

However, most financial advisors agree that an excessive number of funds can create unnecessary complexity.

Monitoring performance, rebalancing allocations, tracking asset distribution, and reviewing fund managers becomes more challenging when a portfolio contains too many schemes.

For an investor contributing around ₹25,000 per month through SIPs, many advisors believe that a portfolio of three to five carefully selected funds is often sufficient to achieve meaningful diversification.

What a Balanced Mutual Fund Portfolio May Look Like

A well-structured portfolio generally includes funds that serve different purposes.

Core Stability Fund

A diversified Flexi-Cap Fund or a Large & Mid Cap Fund can act as the foundation of the portfolio. These funds offer exposure to established companies while maintaining stability during market fluctuations.

Growth-Oriented Fund

A Mid-Cap or Small-Cap Fund can be added to enhance long-term growth potential. These funds carry higher risk but may deliver stronger returns over extended investment periods.

Diversification Fund

Depending on the investor's risk profile, an International Fund or an Index Fund can provide additional diversification. This helps reduce dependence on a single market segment and broadens investment exposure.

Together, these categories can create a balanced portfolio without requiring a large number of mutual fund schemes.

Review Your Portfolio Regularly

Investors who have accumulated multiple SIPs over the years should consider conducting a portfolio review.

Ask yourself:

  • Are several funds investing in similar stocks?

  • Do multiple schemes belong to the same category?

  • Are all funds contributing a unique role in the portfolio?

  • Are some funds consistently underperforming?

If significant overlap exists, consolidating investments into a smaller number of stronger funds may improve efficiency and simplify portfolio management.

Many experts recommend retaining four to five high-quality funds with distinct investment strategies rather than maintaining a long list of similar schemes.

Key Benefits of a Streamlined Portfolio

A focused portfolio can offer several advantages:

  • Easier monitoring and tracking

  • Reduced fund overlap

  • Better diversification across categories

  • Simpler rebalancing process

  • Improved clarity on investment objectives

  • Potentially stronger long-term returns

Conclusion

Building a successful mutual fund portfolio is not about collecting the highest number of SIPs. The goal should be to create a well-diversified portfolio where each fund serves a clear purpose.

Before starting another SIP, investors should evaluate whether the new fund genuinely adds value or simply duplicates existing holdings. In many cases, a thoughtfully constructed portfolio of four or five funds can be more effective than owning ten or more overlapping schemes.

Disclaimer: Mutual fund investments are subject to market risks. Investors should carefully read scheme-related documents and consult a qualified financial advisor before making investment decisions.
