What is a Mutual Fund?

In essence, mutual fund investing is about trusting your money to a professional investment manager and letting them take investment decisions for you.

In essence, mutual fund investing is about trusting your money to a professional investment manager and letting them take investment decisions for you. You take a high level decision to invest through mutual funds and then let the professionals take over from there.

The investment manager collects a pool of money from a large number of investors and makes the day-to-day decisions to invest it in a portfolio of securities or other assets. These could be stocks, bonds, gold, real estate, or some other securities. Each investor in the fund gets a share of the total assets.

You then only need to monitor whether the fund manager is doing a good job for you. If not, fire them by taking your money out!

How it works in practice is as follows:


A reputed financial service company with a track record of managing investments sets up what is called an Asset Management Company (Also referred to as an AMC, mutual fund company, or fund house). Not every one can set up an AMC. They have to get a license from SEBI (the regulator that governs mutual funds in India) by demonstrating a track record and solid financial standing.

After getting a license, the AMC decides what kind of mutual fund they want to offer. They can offer just one or many options. Each is called a Mutual Fund Scheme (commonly shortened to scheme, mutual fund or just fund). They will also appoint one or more named individuals to act as the fund manager for that scheme. While offering the Scheme, the AMC clearly defines the investment objective and the mode of operation of the scheme in a set of Offer Documents the format of which has been specified by the regulator. This ensure that the public investor knows exactly how their money is going to be invested.

Let’s say the fund house offers two schemes:

Scheme 1 invests in stocks and Scheme 2 invests in bonds. You as an investor can choose to invest in whichever one suits your purpose. Like you, thousands of investors will ‘subscribe to’ or ‘buy’ that scheme. The money so collected is the pool of money or ‘corpus’ available for the fund manager. He or she will then take the decisions about which specific stocks to invest that money in.

The total corpus of the mutual fund scheme is sub-divided into Units (or shares), which the investors buy. To begin with the corpus is divided into units of Rs 10.

As the value of the investments made by the mutual fund changes, the value of the units changes as well. This is called the NAV (Net Asset Value) of the unit. It’s calculated by dividing the total value of the net assets of the fund by the number of units. This is published daily so you know how your money is doing. You also get periodic statements with information about your holdings.

The AMC does not do all this for free. They charge a fee for managing the money. In addition there are other costs such as brokerage fees, costs of publishing statements etc. These need to be borne by the investors and are deducted from the corpus periodically. These are called Expenses of the fund and the ratio of expenses to the total money managed by the fund is called Expense Ratio. To protect investors, the regulator SEBI has specified the maximum expense ratio that can be charged. Most fund houses manage to control costs and keep the expenses below the maximum cap.

That was probably a lot of new stuff to learn in one go. But now you can hold your own when your advisor throws these terms at you:

  • Asset Management Company (AMC, Mutual Fund Company or Fund House)
  • SEBI (Securities & Exchange Board of India)
  • Mutual Fund Scheme (Scheme, mutual fund or fund)
  • Offer Documents
  • Units or shares:
  • NAV (Net Asset Value)
  • Expenses, Expense Ratio
