A mutual fund is a portfolio or basket of securities (often stocks or bonds) where investors pool their money. Nationally, there are more than 7,000 mutual funds investors can choose from, spanning equity funds, bond funds, growth funds, sector funds, index funds, and more.
Mutual funds are typically actively managed, where a manager or team of professionals decides which securities to buy and sell, although some are passively managed, where the fund simply tracks an index like the S&P 500. The main differences among mutual funds typically come down to their investment objectives and the strategies they use to achieve them.
Key Points
• Mutual funds pool money from many investors to build a diversified portfolio of securities.
• Equity funds are higher risk, but have the potential to offer higher long-term growth; bond funds are typically lower risk, but may provide steady income.
• Money market funds are structured to be highly illiquid and low risk, typically appropriate for short-term investments
• Index funds passively track market indices, and may offer lower fees and tax efficiency.
• Balanced funds have a (typically) fixed allocation of stocks and bonds, which may be suitable for moderate risk investors.
How Mutual Funds Work
Mutual funds pool money from many investors to buy a diversified mix of securities, known as a portfolio. These may include:
• Stocks
• Bonds
• Money market instruments
• Cash or cash equivalents
• Alternative assets (such as real estate, commodities, or precious metals)
Mutual funds are typically open-end funds, which means shares are continuously issued based on demand, while existing shares are redeemed (or bought back). In contrast, a closed-end fund issues a set number of shares at once during an initial public offering.
You can buy mutual fund shares through a brokerage account, retirement plan, or sometimes directly from the financial group managing the fund. For example, you might hold mutual funds inside a taxable investment account, within an individual retirement account (IRA) with an online brokerage, or as part of your 401(k) at work.
One of the main advantages of mutual funds is the potential for diversification. If one holding underperforms or loses value, the other investments in the fund may help offset those losses, reducing overall portfolio risk.

9 Types of Mutual Funds
Before adding mutual funds to your portfolio, it’s important to understand the different types. Some funds aim for growth, while others focus on steady income. Certain mutual funds may carry a higher risk profile than others, though they may offer the potential for higher rewards.
Knowing more about the different mutual fund options can make it easier to choose investments that align with your goals and tolerance for risk.
1. Equity Funds
• Structure: Typically open-end
• Risk Level: High
• Goal: Growth or income
• Asset Class: Stocks
Equity funds primarily invest in stocks to pursue capital appreciation and potential income from dividends. The types of companies an equity fund invests in will depend on the fund’s objectives.
For example, some equity funds may concentrate on blue-chip companies that tend to offer consistent dividends, while others may lean toward companies that have significant growth potential. Equity funds can also be categorized based on whether they invest in large-cap, mid-cap, or small-cap stocks.
Investing in equity funds can offer the opportunity to earn higher rewards, but they tend to present greater risks. Since the prices of underlying equity investments can fluctuate day to day or even hour to hour, equity funds tend to be more volatile than other types of mutual funds.
2. Bond (Fixed-Income) Funds
• Structure: Typically open-end; some closed-end
• Risk Level: Low
• Goal: Steady income
• Asset Class: Bonds
Bond funds invest in debt securities, such as government, municipal, or corporate bonds. They give investors a convenient way to access the fixed-income market without buying individual bonds. Some bond funds try to mirror the broad bond market and include short- and long-term bonds from a wide variety of issuers, while other bond funds specialize in certain types of bonds, such as municipal bonds or corporate bonds.
Generally, bond funds tend to be lower risk compared to other types of mutual funds, and bonds issued by the U.S Treasury are backed by the full faith and credit of the U.S. government. However, bonds are not risk-free. Bonds are typically sensitive to interest rate risk (meaning their market value fluctuates inversely with changes in interest rates), as well as credit risk (since a bond’s value is directly tied to the issuer’s ability to repay its debt).
3. Money Market Funds
• Structure: Open-end
• Risk Level: Low
• Goal: Income generation
• Asset Class: Short-term debt instruments
Money market funds invest in high-quality, short-term debt from governments, banks or corporations. This may include government bonds, municipal bonds, corporate bonds, and certificates of deposit (CDs). Money market funds may also hold cash and cash equivalent securities.
Money market funds can be labeled according to what they invest in. For example, Treasury funds invest in U.S. Treasury securities, while government money market funds can invest in Treasuries as well as other government-backed assets.
In terms of risk, money market funds are considered to be very low risk. That means, however, that money market mutual funds tend to produce lower returns compared to other mutual funds.
It’s also worth noting that money market funds are not the same thing as money market accounts (MMAs). Money market accounts are deposit accounts offered by banks and credit unions. While these accounts can pay interest to savers, they’re more akin to savings accounts than investment vehicles. While money market accounts may be covered by the Federal Deposit Insurance Corporation (FDIC), money market funds may alternatively be insured by the Securities Investor Protection Corporation (SIPC).
4. Index Funds
• Structure: Open-end
• Risk Level: Moderate
• Goal: To replicate the performance of an underlying market index
• Asset Class: Stocks, bonds, or both
Index funds are designed to match the performance of an underlying market index. For example, an index fund may attempt to mirror the returns of the S&P 500 Index or the Russell 2000 Index. The fund does this by investing in some or all of the securities included in that particular index, a process that’s typically automated. Because of this, index funds are considered passively managed, unlike actively managed funds where a manager actively trades to try to exceed a benchmark.
Because index funds need much less hands-on management and don’t require specialized research analysts, they’re generally lower cost than actively managed funds. They’re also considered to be more tax-efficient due to their potentially longer holding periods and less frequent trading, which may result in fewer taxable events. However, an index fund may include both high- and low-performing stocks and bonds. As a result, any returns you earn would be an average of them all.
5. Balanced Funds
• Structure: Open-end
• Risk Level: Moderate
• Goal: Provide both growth and income
• Asset Class: Stocks and bonds
Balanced funds, sometimes referred to as hybrid funds, typically contain a fixed allocation of stocks and bonds for investors interested in both income and capital appreciation. One common example of a balanced fund is a fund that invests 60% of its portfolio in stocks and 40% of its portfolio in bonds.
By holding both growth-oriented equities (stocks) and stability-focused, fixed-income securities (bonds) in one portfolio, these funds aim to provide a middle ground between the high-risk/high-return profile of equity funds and the low-risk/low-return profile of bond funds. Balanced funds automatically maintain their asset allocation and may make sense for moderately conservative, hands-off investors seeking long-term growth potential.
6. Income Funds
• Structure: Open-end
• Risk Level: Low to moderate
• Goal: Provide steady income
• Asset Class: Bonds, income-generating assets
Income funds are designed with the goal of providing investors with regular income through interest or dividends, rather than focusing mainly on long-term growth. Some income funds focus on bonds, such as government, municipal, or corporate bonds, while others mix equities with bonds to offer a diversified approach to income generation.
Though not risk-free, income funds are generally lower risk than funds that prioritize capital gains. This type of mutual fund can be appealing to investors who value stability and regular cash flow, such as retirees. Income funds may also help balance risk in any investor’s portfolio, especially in uncertain markets.
7. International Funds
• Structure: Mostly open-end
• Risk Level: High
• Goal: Growth or income outside the U.S.
• Asset Class: Global equities and bonds (excluding U.S. securities)
International mutual funds invest in securities and companies outside of the U.S. This sets them apart from global funds, which can hold a mix of both U.S. and international securities. Some international funds focus on developed economies, while others target emerging markets, which may offer higher growth but come with higher risk.
Adding international funds to a portfolio can increase diversification and access to global opportunities if you’ve primarily invested in U.S. companies or bonds so far. But keep in mind that international funds can carry unique risks, including the risk of currency volatility and changing economic or political environments, especially in emerging markets.
8. Specialty Funds
• Structure: Open or closed-end
• Risk Level: Varies
• Goal: Thematic or sector-specific investing
• Asset Class: Equities, bonds, alternatives
A specialty fund concentrates on a specific sector, industry, or investment theme, such as technology, health care, or clean energy. They allow investors to target specific opportunities and expand their portfolios beyond traditional stocks or bonds. Specialty funds can offer exposure to assets like real estate, commodities, or even precious metals. You could also use specialty funds to pursue specific investing goals, such as investing with environmental, social, and governance (ESG) principles in mind.
Because of their narrower focus, specialty funds frequently offer less diversification, which means they may come with higher potential risks. This type of mutual fund is generally best suited for investors with a deep understanding of the target market.
đź’ˇ Quick Tip: Spreading investments across various securities may help ensure your portfolio is not overly reliant on any one company or market to do well. For example, by investing in different sectors you can add diversification to your portfolio, which may help mitigate some risk factors over time.
9. Target Date Funds
• Structure: Typically open-end
• Risk Level: Declines over time
• Goal: Retirement planning
• Asset Class: Mix of stocks, bonds, and short-term investments
Target date funds are mutual funds that adjust their asset allocation automatically so the fund becomes more conservative as the target (typically retirement) date approaches. For example, if you were born in 2000 and plan to retire at 65, you would invest in a 2065 fund. As you get closer to retirement age, your target date fund will gradually become more conservative, increasing its allocations to bonds, cash, or cash equivalents.
Like mutual funds, target date funds are offered by nearly every investment company. In most cases, they’re recognizable by the year in the fund name. If you have a 401(k) at work, you may have access to various target date funds for your portfolio.
While target date funds offer a “set it and forget it” option for retirement planning, they are a one-size-fits-all solution that does not account for an individual’s unique financial situation, risk tolerance, or outside assets. Some investors may prefer a more aggressive or conservative allocation than the one the fund provides.
What’s the Difference Between Mutual Funds and ETFs?
It can be easy to confuse exchange-traded funds (ETFs) with mutual funds, since they have a number of similarities. Both are baskets of securities designed to provide diversification. And both can hold stocks, bonds, or a mix, or follow specific themes or strategies.
However, ETFs and mutual funds differ in several key ways:
• Trading: ETFs trade throughout the day like stocks, while mutual funds are priced only once daily after the market closes.
• Liquidity: Because they trade on exchanges throughout the day, ETFs are generally more liquid than traditional mutual funds.
• Management: Most EFTs are passively managed, while mutual funds are typically actively managed.
• Cost: Because they are largely passively managed, EFTs often carry lower expenses ratios.
The Takeaway
Mutual funds are among the most accessible and flexible investment options available. With choices ranging from conservative money market funds to aggressive equity and specialty funds, there’s a fund for nearly every type of investor.
The best mutual fund for you depends on your goals, time horizon, and tolerance for risk. Whether you’re seeking steady income, long-term growth, international exposure, or a hand-off retirement plan, understanding the different types of mutual funds can help you build a portfolio that supports your financial future.

FAQ
What are the four main types of mutual funds?
The four main types of mutual funds are equity funds, debt funds, money market funds, and hybrid funds.
Equity funds invest primarily in stocks and aim for long-term capital growth. Debt funds focus on fixed-income securities like bonds, offering relatively stable returns. Money market funds invest in short-term, low-risk instruments such as Treasury bills. Hybrid funds combine equity and debt securities in varying proportions to balance risk and reward. Each type suits different investor goals, risk tolerances, and time horizons.
What is the 7-5-3-1 rule in SIP?
The 7-5-3-1 rule in SIP (systematic investment plan) is a guideline for disciplined investing. The 7 suggests staying invested for at least seven years to reap the benefits of compounding and market growth. The 5 suggests diversifying your investments across at least five different mutual fund categories to help reduce risk. The 3 is about overcoming three common mental hurdles investors face (disappointment, frustration, and panic). The 1 suggests increasing your SIP amount every year to improve your return potential in the long term.
Which type of mutual fund is best?
The “best” type of mutual fund depends on your goals, risk tolerance, and time horizon. For long-term wealth creation, equity funds often provide the highest growth potential but come with more risk. For those prioritizing stable returns, debt funds or money market funds may be a favorable choice. Investors seeking balance may prefer hybrid funds. The best fund is one that is aligned with your unique financial objectives.

Investment Risk: Diversification can help reduce some investment risk. It cannot guarantee profit, or fully protect in a down market.
S&P 500 Index: The S&P 500 Index is a market-capitalization-weighted index of 500 leading publicly traded companies in the U.S. It is not an investment product, but a measure of U.S. equity performance. Historical performance of the S&P 500 Index does not guarantee similar results in the future. The historical return of the S&P 500 Index shown does not include the reinvestment of dividends or account for investment fees, expenses, or taxes, which would reduce actual returns.
Investing in an Initial Public Offering (IPO) involves substantial risk, including the risk of loss. Further, there are a variety of risk factors to consider when investing in an IPO, including but not limited to, unproven management, significant debt, and lack of operating history. For a comprehensive discussion of these risks please refer to SoFi Securities’ IPO Risk Disclosure Statement. This should not be considered a recommendation to participate in IPOs and investors should carefully read the offering prospectus to determine whether an offering is consistent with their investment objectives, risk tolerance, and financial situation. New offerings generally have high demand and there are a limited number of shares available for distribution to participants. Many customers may not be allocated shares and share allocations may be significantly smaller than the shares requested in the customer’s initial offer (Indication of Interest). For more information on the allocation process please visit IPO Allocation Procedures.
Tax Information: This article provides general background information only and is not intended to serve as legal or tax advice or as a substitute for legal counsel. You should consult your own attorney and/or tax advisor if you have a question requiring legal or tax advice.
An investor should consider the investment objectives, risks, charges, and expenses of the Fund carefully before investing.

Alternative investments, including funds that invest in alternative investments, are risky and may not be suitable for all investors. Alternative investments often employ leveraging and other speculative practices that increase an investor's risk of loss to include complete loss of investment, often charge high fees, and can be highly illiquid and volatile. Alternative investments may lack diversification, involve complex tax structures and have delays in reporting important tax information. Registered and unregistered alternative investments are not subject to the same regulatory requirements as mutual funds.
Please note that Interval Funds are illiquid instruments, hence the ability to trade on your timeline may be restricted. Investors should review the fee schedule for Interval Funds via the prospectus.
