An index is a way of tracking the performance of a group of assets using a standardized metric. These indices could either be broad-based, like the Standard & Poor’s 500 Index (S&P 500), Dow Jones Industrial Average (DJIA), or more specialized indexes that focus on a particular industry or segment.

Indexes can be used to compare the performance of a portfolio’s returns. A popular investment strategy is to replicate an index passively, rather than trying to outperform it. If a fund mirrors the stock market or a section of it, the fund’s performance will equal that of the market.

You cannot investment in a specific market index, but you can in an index fund that tracks the market index.

Index funds are a type of mutual fund or ETF whose portfolio is designed to track a specific financial market index, such as the S&P 500. The fund doesn’t aim to exceed the performance of the stock market index, but rather to match it as closely as possible.

An index fund is a good investment option for people who want a broad range of securities and low overall risk. Index funds have low operating expenses and low portfolio turnover, which makes them a good choice for investors.

Index funds are managed in a way that requires less effort, meaning they usually only contain what is already in the index. This results in a lower expense ratio than what is needed for actively managed funds. This means that investors can expect to pay lower fees for their investment managers, but still receive the same return on their investment.

An index fund investor will not usually experience a total loss as the diversification is high and the book value is taken into account. Because index funds are a collection of many different stocks, they are considered a relatively safe investment compared to investing in a single stock.

Actively Managed Vs. Passive Funds: Know The Difference

Index funds can either be actively or passively managed.

A fund manager creates an active fund by selecting a group of companies from a specific index and making changes to improve the fund’s performance. The goal of an actively managed index fund is to outperform the market, which is not easy to do.

A passive fund is a fund where the portfolio tracks the performance of a group of investments that does not change.

Many investors prefer passive funds over active funds because the market usually performs better than individual securities. Additionally, passive funds have lower expense ratios because you don’t have to pay an account manager to handle the investment.

In this light, it’s the best of both worlds. When you invest in an ETF, you are able to invest in many different securities at once. This allows you to spread your risk out and diversify your holdings without having to absorb a ton of trading costs.

Pros & Cons of Index Investing

Pros & Cons of Index Fund Investing

Index funds are popular with investors for several reasons. Most importantly, they allow for high portfolio diversification. Thus, managing risk and offsetting potential losses. However, if you only pick low-risk stocks, you may not make as much money as you could if you picked stocks with higher risks, which could result in much higher returns.


  • High diversification: these funds allow you to hold a stake in hundreds or thousands of companies at once;
  • Low-risk: diversification cuts back on risk. The poor performance of one company won’t be as damaging when you own so many;
  • Low fees: index funds tend to have lower costs (expense ratios) than actively managed funds. The fund’s operating costs are reduced since there’s no need for portfolio managers or stock analysts or to pay commissions that arise from constant trading;
  • Stable performance: index funds have consistently beaten other types of funds in terms of total return. For instance, index funds that track the S&P 500 have historically delivered an average 10 percent annual return over long periods;
  • Easy to acquire: buying into an index fund gives you access to an investment portfolio of a vast basket of securities. The time and expertise to build and maintain a similar portfolio yourself would likely be unthinkable;
  • Transparency: many index funds simply keep what’s in the index, so you can always see the fund’s holdings, letting you better judge an index fund’s risk based on those holdings;
  • Lower taxation: by trading in and out of securities less frequently than actively managed funds, index funds generate less taxable income that will be passed along to their shareholders.


  • Lack of flexibility: index funds aren’t likely to deliver a return higher than the benchmark. While the investor is guaranteed the index’s return when the market rallies, so too the index’s loss when the market plunges;
  • Average annual returns: index funds may provide a high degree of diversification, which also means they deliver only average yearly returns. Index funds can dilute the possibility of considerable gains as they are driven by the combined results of a massive basket of assets;
  • Unlikely significant short-term gains: as passive investing vehicles, there’s little scope for capturing major short-term gains with index funds;
  • Tracking error: this is the variation between an index fund’s return and the performance of its parent index, mirrored by the costs to run a portfolio. Always go for the one with a slighter tracking error when you’re comparing index funds that track the same index;
  • Management differences: index funds are not always objective as they’re created by companies that decide an index’s composition. In addition, the decision-making process isn’t always appropriately regulated nor transparent and can be influenced by overall management tactics. Moreover, sometimes the index funds and the parent index have the same managers, which can create a conflict;
  • Vulnerable to market swings and crashes: Many index funds are formed on a market capitalization basis, meaning the top holdings have inflated weight on overall market movements. For example, it would substantially affect the entire index if heavyweights such as Inc. (AMZN) and Meta Platforms Inc. (FB) experienced a weak quarter.
