Index Funds: Definition, How It Work, and More

Index Funds comprise securities that follow an index or benchmark. These can be Mutual Funds or Exchange-Traded Funds (ETFs). These funds are passively managed funds and try to copy the securities that are included in the index.

Deeper Definition

An index fund is a type of investment fund that tracks the performance of an index. It can be a Mutual Fund or an Exchange-Traded Fund (ETF).

Instead of hand-picking stocks or bonds, an index fund selects securities from an index. It offers generic diversification of risk and dependable income options for investors. Investors cannot directly invest in an index, but they can in an index fund.

These funds are standard or industry benchmarks. All of the Stock markets have indexes that index funds follow these days. Investors putting their money in these funds mimic an investment in the index itself.

How Does It Work?

The idea of index funds is to follow the performance of an index. Indices follow a set of securities that can be from a specific industry or a geographical market. Fund managers try to match the performance of these indices by building a similar fund called an index fund.

These funds are created in proportion to the securities held by indices. It is to mitigate market risks and follow the performance of an index as closely as possible. This fund creates natural diversification for investors as well. It also means these fund portfolios will not change substantially unless the index changes itself. Index fund managers try to keep the same proportion of the securities held in an index.

These funds are passively managed funds. It means there are lower expense ratios with these funds than actively managed mutual funds. Lower expense and passive management also mean there are lower returns for investors in the short term. However, investors can expect high investment returns from these funds in the long term. As these funds follow indices that are curated selections of securities, they should perform well over the long run.

Special Considerations with Index Funds

Passive investments follow different management strategies than actively managed funds. One such strategy is to buy and hold the securities for a longer run. These funds also follow the same footprint. These funds seek to maximize gains in the long term, rather than creating quick short-term gains.

A core aspect of these funds is to follow the index. It means they try to match the performance of the index, rather than trying to beat the performance. This strategy limits the returns for investors up to the benchmark index returns but it also reduces the risks.

Investors cannot directly invest in an index. When they invest in an index fund, it mirrors their holding in the index. It also creates transparency for investors as they know which securities they are holding. Investors can match their index fund performance easily against the index performance. It also makes the index fund manager’s job easier, as they do not need to invest a lot in research and analyses as they do for active investment strategies.
