How To Use Index Funds

But what exactly are they? Index funds copy real stock market indices, like the S&P 500. In that case, you’d get shares for each of the five hundred firms that make up the S&P.

It’s safe to say, these aren’t as flashy as crypto but it balances things out by giving much more stability traditionally, making a good accompaniment to many different portfolios up to retirement. Let’s look at how to invest in index funds.

Why Invest in Index Funds?

Like automated website revenue, investments in index funds use a passive investment method.

What Are Index Funds

By comparison, active managers decide when to acquire and sell shares in the biggest companies, from Amazon to emerging economy companies like Alibaba. In fact, management costs for actively managed investments are often greater than those for passively managed investments since someone is actively selecting the assets. If you’re interested in learning more, active investment management is used by many mutual funds.

However, for index funds, passive management will be used, which refers to a style of investing in which a manager constructs a portfolio of securities to mirror an existing market index. The stocks that make up a market index are connected to one sector of the economy.

The S&P 500, for instance, is an indicator of 500 leading U.S. firms' stock performance. The S&P 500 index is widely seen as a barometer of the state of the American economy and the stock market. (Another example is the U.K.’s FTSE 100.)

In other words, there isn’t much for you to do. To mimic a market index, an index fund will include assets with similar characteristics.

Because of this lack of active management, index funds often have results highly correlated with those of the index they track.

For that same reason, more investors are turning to hosted ⚡ asset channels to invest their cash.

Advantages ✅

While fund managers put a lot of effort into “beating the market” (i.e., an index of the market), they seldom succeed. And even if they do, they're probably not going to be able to keep beating the market for very long.

Just 29% of actively managed funds outperformed the S&P 500 in 2019, according to data from SPIVA, a division of S&P Global. Yet, just 9% of those funds were able to outperform their benchmark in 2021.

Index funds, which are passively managed and simply track the market's performance, often provide investors with higher long-term returns than actively managed funds, which tend to underperform it. They are also less expensive.

Steps: How to Invest in Index Funds?

It's simple to invest in index funds even if you’re busy running your business. The steps involved are briefly described below.

Index Fund

Step 1 📗: Establish a Plan

Knowing your financial goals is essential before putting money into index funds. Individual stocks or even cryptocurrencies may be more appealing if you're seeking to earn a million in a few years and are ready to take on a lot of risk.

Yet index funds might be a terrific addition to your portfolio if you want your money to increase steadily over time, which is especially important if you're saving for retirement.

Step 2 📘: Research

Finding the appropriate index funds to invest in is the next step after deciding the index you want to follow. There are several things to think about while researching index funds. To help, here are a few things to remember:

  • Capitalization. Index funds can follow the performance of firms of any size (also known as small-, mid- or large-cap indexes).
  • Geography. The equities traded on foreign markets, or on various international exchanges, are the primary focus of certain investment vehicles.
  • The economic sphere. You may research funds that invest primarily in sectors like consumer goods, IT, and health-related companies.
  • Classification of the Assets. Some funds mirror the performance of many asset classes, including domestic and international bonds, commodities, and cash.
  • Potential in the marketplace. These funds research potential investments in developing markets or other new yet expanding industries.

Despite the variety of options, you may only need to put money into one. Warren Buffett, one of the most successful investors of all time, has famously claimed that most people can get all the diversification they need by purchasing a wide stock market index.

Portfolio allocations may be simply modified to increase exposure to target markets (such as more emerging market exposure, or a higher allocation to small companies or bonds).

Step 3 📙: Choose

Next, choose some index funds.

After settling on an index of interest, the next step is to choose an index fund tracking that index. It usually comes down to money.


In comparison to other investment options, index funds have relatively low fees. Since they are programmed to automatically track changes in an index's value, they need nothing in the way of ongoing maintenance and cost little to operate. Yet, not all index mutual funds are inexpensive.

They still have overhead since someone has to manage them, even if it's not a team of highly-paid analysts. Each investor's return on investment in a mutual fund is reduced by these fees based on their proportion of the fund's total investment.

Even if two funds have the same investment objective, such as replicating the S&P 500, they may have vastly different management fees. Even a modest increase in fees, even by a fraction of a percentage point, may have a significant impact on your investment results over the long run. The larger the fund, the cheaper the management costs are.

Step 4 📖: Open an account

Consider your options for purchasing index funds, and then commit to one.

You may get index funds from any good brokerage or mutual fund business.

The same holds true for exchange-traded funds (ETFs), which function similarly to miniature mutual funds but are exchanged like stocks throughout the day (more on these below).

Things to think about when deciding where to invest in an index fund:

Choice of funds. Would you want to invest in a wide range of index funds from different fund families? Large mutual fund firms may offer a smaller variety of rival funds than a bargain broker.

Price of trade. You should think about how much you'll have to pay to acquire or sell an index fund if the commission or transaction fee isn't waived by your broker or the fund provider. Commissions for trading mutual funds may be as high as £20, compared to less than £10 for trading equities and ETFs.

The power of impact investment. Want to have an impact beyond your portfolio with your investment? Some index funds follow benchmarks that seek businesses committed to ecological or social responsibility. Get an understanding of impact investment.

Options with no service fees. Do they provide commission-free ETFs or mutual funds? With bargain brokers, this is a crucial factor in the evaluation process.

Convenience. Locate a service that can meet all of your requirements. For those planning to invest only in mutual funds (or a combination of mutual funds and equities), for instance, a mutual fund business may be able to act as a central location for all of their financial needs. A bargain broker that offers the required index funds could be preferable if extensive stock research and screening are necessary. For those of you who don't already have one, these are the steps you need to do to create a brokerage account.

Step 5 💸: Invest

Now, invest in index funds.

Now that you know how to invest in index funds, you need to get access to specific investment funds to buy shares of an index fund. After selecting a brokerage in Step 3, you can create various investment accounts, including standard brokerage accounts and ISAs. From there, you may invest in the fund.


The amount you invest in the fund, or the number of shares you acquire, may be predetermined when you make your first investment. Your risk tolerance and the cost per share of the index fund will influence how much you can invest. If you want to put £1,000 in an index fund but only want to pay  £100 per share, you may buy 10 shares for your £1,000.

Step 6 📕: Revisit Often

Check your index funds often.

Due to its low entry barrier, immediate diversification, and higher returns than actively managed accounts, index funds have quickly become one of the most popular methods for Americans to invest. While your index fund is managed passively, it doesn't imply you should forget about it. A few things to keep in mind throughout time are as follows:

Can we trust the index fund to perform? Index funds are designed to replicate the performance of an underlying index. Mutual fund performance quotation pages typically display the index fund's results. It compares the index fund's performance across different time periods with that of the reference index. If the numbers aren't an exact match, there's no need to freak out.

Keep in mind that investing fees, no matter how little, and taxes will have an impact on your final earnings. If the fund's performance behind the index by more than the cost ratio, though, red flags should flare.

Are you unable to afford the index fund of your choice? It may be time to reassess your index fund if the costs become excessive over time.

Want to put your money into stocks instead? You may wish to look into stocks if you're interested in active investing. Here are detailed instructions on how to invest in stocks.

Choosing How to Invest in Index Funds

The next part of our guide on how to invest in index funds deals with more practical matters of cost and where to look.

The Hidden Cost Of Index Funds


Although index funds often have lower expenses than other types of investments, they nonetheless may have some.

Trading minimum. To invest in a mutual fund, you may need as little as a pound or as much as several thousand. Most funds enable investors to contribute in smaller amounts after they have passed that point.

Account minimum. This is not the same as the bare minimum required to invest. The investment minimum for a certain index fund persists even if the brokerage account minimum is zero (as is usual for consumers who start a regular or ISA account).

Expense ratio. Among the most significant expenses associated with an index fund is this. The expense ratio measures the amount by which fees are deducted from the returns of a fund's investors periodically as a proportion of the total amount invested. The cost ratio may be found in the mutual fund's prospectus or by researching a mutual fund online.

Margin after taxes. Owning the fund might result in capital gains taxes if it is kept outside of a tax-deferred account like a pension or ISA, in addition to the costs that would be charged to purchase the fund. These taxes, like the expenditure ratio, may reduce investment returns.

Best Index Funds

So you are looking to diversify your portfolio and are wondering which index would be best…

Mutual funds that “index” to a certain index. The S&P 500, for instance, is one of the most well-known indices since the 500 firms it follows are all household names operating in different sectors of the US economy. Yet, the S&P 500 isn't the only index available. Instead, you might try these additional possibilities:

The Nasdaq Composite Index tracks the performance of over 3,000 technology-focused stocks traded on the Nasdaq Stock Market.

The Dow Jones Industrial Average is a stock market index that tracks the performance of 30 of the largest publicly traded firms in the United States.

To be included in the Wilshire 5000, a company must have its main office in the United States and be actively trading on a stock exchange; this index is often considered to be a “complete stock market index”.

Meanwhile, the FTSE Global All Cap Index includes equities from all around the world, including both established and developing economies, and a wide variety of market capitalizations.
