How Many Mutual Funds Should You Own Finding the Right Portfolio Size

img

Introduction

Many investors believe that owning more mutual funds automatically creates better diversification. But if you have too many similar funds it can make your investments hard to manage, without adding much diversification. 

So how many mutual funds should I invest in? Your answer depends on your financial objectives, risk tolerance, investment horizon and overall asset allocation. The emphasis should be on quality and purpose, rather than on the number of schemes for a well-structured mutual fund portfolio.

Build the right mutual fund portfolio for your goals 

How Many Mutual Funds Should I Invest In?

There's no one size fits all. It is contingent upon your financial situation and your reasons for investing.

1. You are able to build simple portfolio with just a handful of funds

A smaller portfolio is easier to follow and to keep track of. Don’t choose a lot of funds, rather choose the funds that satisfy different needs.

Here is a simple way to help you:

  • Avoid unnecessary duplication

  • Easily monitor investments

  • Make asset allocation more clear

  • Stay on track with financial objectives

When you ask how many mutual funds should I invest in, the answer is that quality is usually more important than quantity.

2. More Funds Do Not Always Mean More Diversification

Five or six funds does not equal a well diversified portfolio. There may be some overlap in the companies they hold or the strategies they use between funds.

Owning multiple large-cap funds can lead to a lot of overlap.

Before adding another fund, make sure to check:

  • Top holdings

  • Sector distribution

  • Style of Investment

  • Market cap exposure

3. Consider Your Investment Goals

Your goals can influence the number and type of funds you need.

Common goals include:

  • Retirement

  • Children's education

  • Wealth creation

  • Home purchase

  • Short- and medium-term financial needs

A goal-based approach can help you determine how many mutual funds should I invest in without unnecessarily expanding your portfolio.

Factors That Determine the Right Mutual Fund Portfolio Size

Your mutual fund portfolio should be the right size for you, which depends on a number of personal factors. Don’t worry about how many investments you need, worry about how each investment fits into the overall plan.

1. Monetary Goals

Different goals may call for different investment strategies and different time horizons.

2. Taking Risks

The investor’s tolerance for equity volatility will guide their portfolio construction.

3. Investment time horizon

Shorter term goals may require more stability whereas longer term goals can usually afford to have more equity exposure.

4. Availability of Investment

Investment size should determine portfolio size. Too many funds with too little invested in each can make the portfolio unnecessarily complicated.

5. Distribution to current assets

Review all of the investments you hold in your portfolio which include:

Equity Debt

Gold Term Deposit

Other Investment.

6. Knowledge and Experience in Investments

For less experienced investors, keeping the portfolio simple and easy to understand can be helpful.

2. Medium-Sized Portfolio

A medium-sized portfolio can include additional categories when they provide a clear diversification benefit.

How to Build a Balanced Mutual Fund Portfolio

A good mutual fund portfolio should be built around purpose rather than the number of funds you own.

1. Start With Core Funds

Core funds can provide broad exposure and form the foundation of your portfolio.

Consider:

  • Diversified equity

  • Broad-market exposure

  • Long-term growth funds

2. Add Funds for Specific Purposes

Additional funds may be useful when they provide exposure that your existing portfolio lacks.

Examples include:

  • Mid-cap exposure

  • Debt allocation

  • International exposure

  • Tax-saving investments

3. Avoid Unnecessary Overlap

Before adding a new fund, compare it with your existing investments.

Check whether the funds have:

  • Similar top holdings

  • Similar sector exposure

  • Similar investment strategies

  • Similar market-cap allocation

4. Maintain Appropriate Asset Allocation

Your mutual fund portfolio should reflect your risk tolerance and investment horizon.

A younger investor with a long-term goal may have a different allocation from someone approaching retirement.

Mutual Fund Investment: When Should You Add Another Fund?

Another fund should be added to fill a particular need of the portfolio, not just to add more investments.

1. When Your Money Target Changes

A new goal could mean a new way of investing.

2. When you need to rebalance your portfolio

If your existing portfolio has a mismatched ratio of equity and debt then you need another category of fund.

3. Diversification and New Product Line Introduction

Only add a fund if it gives you exposure you don’t already have in your existing investments.

4. If Your Risk Profile Changes

Age, income, responsibilities or financial objectives can change and require adjustments to the portfolio.

5. You have a hole in your existing portfolio

Before you add anything else, look at your portfolio. If a key category is absent, then a new purchase may make sense.
