Mutual fund investments are passive investments where fund managers handle the investor’s fund and decide where to invest for maximum capital appreciation. Your mutual fund investments are reinvested, significantly boosting your investment value over the long term.

How Do Mutual Funds Work?

In mutual funds, funds are pooled from many investors to invest in securities based on the mutual fund type. This collected money is managed by experienced fund managers who have a good track record of predominantly profitable investments. Investors don’t have to worry about research or managing their money, making it suitable for beginners in investing or individuals who don't have the time to research stocks or manage their portfolio themselves.

When you invest in mutual funds, you don’t get stocks, instead, you get mutual fund units. These units represent part-ownership of the underlying assets held in the mutual fund’s portfolio. The value of these units is presented by NAV (Net Asset Value). The NAV of mutual fund units changes daily as per the market performance of the fund’s investments.

Since mutual funds invest in various markets, the NAV of mutual fund units mirrors the market’s volatility. If the market is bullish, the NAV will be high and if the markets fall, so will the NAV of your mutual fund units.

Let’s say you invested in an equity mutual fund that invests exclusively in the IT sector stocks. In case of any news or event, the stock prices of the IT sector fall, the NAV of MF units will fall too. Whereas, if IT sector stock prices rise, so will the MF unit’s NAV.

Types of Mutual Funds

There 3 main types of mutual funds you can invest in based on your risk appetite and financial goals.

Equity Mutual Funds

Equity Mutual Funds invest exclusively in stock, 75% of the funds must be invested in equity. Such mutual funds aim for long-term capital appreciation and wealth creation. Since this fund predominantly invests in equities, it carries high risk with potential for high returns.

Debt Mutual Funds

As the name suggests, debt mutual funds invest in fixed income instruments such as government securities, corporate bonds and money market instruments. These funds carry low risk compared to equities and offer stable returns to investors.

Debt Mutual funds are suitable for risk-averse investors who are comfortable with modest returns. There are sub-categories of Debt mutual funds, such as liquid funds, short-term funds and dynamic bond funds.

Hybrid Mutual Funds

Hybrid mutual funds invest in multiple asset classes and combine both equity and debt for a diversified portfolio. Hybrid Mutual Funds carry moderate risks and are suitable for investors looking for a balanced approach towards investing.

How to Invest in Mutual Funds?

There are two methods you can invest in mutual funds.

  • Systematic Investment Plan (SIP)

In SIP, you have to invest a fixed amount of money at regular intervals, such as weekly, monthly, or quarterly, based on your preference. SIPs build financial discipline and are suitable for investors seeking long-term capital appreciation through small investments over time.

  • Lumpsum

In a lump sum, you invest a large amount of money one time instead of in instalments. This isn’t very popular and is only suitable for investors in possession of a significant amount of money.

Factors Affecting Your Mutual Fund Investments

Here are the factors that affect your mutual fund’s performance.

Market Movement

Market movement is an important factor that influences the performance of your mutual fund investments. As mutual funds invest in various markets, they mirror the movement of these markets. If the markets are down, your mutual fund investment will be down as well and vice versa.

Net Asset Value (NAV)

NAV is the cost of a mutual fund and is a metric used to assess the performance of your mutual fund investments. The NAV of units changes daily, reflecting the change in market price of the underlying securities.

Asset Under Management (AUM)

The funds are gathered from various investors to invest in various securities such as stocks, bonds, and other securities. The total value of these assets is called ‘Asset Under Management’. The AUM of a fund changes as per market conditions, making it a dynamic figure.

Fund Managers

Fund Managers are experienced professionals responsible for managing the fund’s investments. They have to make smart trading decisions and optimise the performance of the investments held under the mutual fund.

Investment Objective

Every mutual fund has an investment objective that tells you for whom that fund is suitable. The fund’s investment objective guides the investment strategy and investment decisions.
