Understanding Index Funds

Investing in index funds can be a great way to gain exposure to a particular market segment or asset class. But before we dive into the specifics of index funds, let's first understand what benchmarking is.

What is Benchmarking?

Benchmarking is the practice of comparing the performance of an investment portfolio or security against a standard or measure known as a benchmark. Benchmarks are typically broad market and market-segment stock and bond indexes.

They are used to evaluate the performance of securities, mutual funds, exchange-traded funds, portfolios, or other investment instruments.

How Does Benchmarking Relate to Index Funds?

Index funds are a type of mutual fund or exchange-traded fund that seeks to replicate the performance of a particular benchmark index. For example, an S&P 500 index fund would aim to match the performance of the S&P 500 index.

Index funds are considered a passive investment approach because they do not involve active management of the portfolio.

Instead, they aim to match the performance of the benchmark index by holding a similar mix of securities.

Benchmarks are used to evaluate the performance of index funds. The benchmark index is the standard against which the performance of the index fund is measured. Investors can use benchmarks to check their portfolio's performance and compare it to the performance of the benchmark index.

Portfolio managers use benchmarks as a gauge for the performance of a portfolio against its investing universe.

They will generally choose a benchmark that is aligned with their investing universe.

Active managers seek to outperform their benchmarks, meaning they look to create a return beyond the return of the benchmark.

Index Funds versus Actively Managed Funds

Index funds and actively managed funds are two types of mutual funds that differ in their investment strategies. Here are the key differences between index funds and actively managed funds:

Index Funds:

  • Invest in a specific list of securities, such as stocks of S&P 500-listed companies only.
  • Seek to match the performance of a specific market benchmark (or "index") as closely as possible.
  • Have lower fees than actively managed funds.
  • Provide an easy way to diversify your portfolio by replicating the performance of the stock market.
  • Follow a passive investment strategy and maintain more or less the same mix of securities over time.

Actively Managed Funds:

  • Invest in a changing list of securities, chosen by an investment manager.
  • Try to outperform the market.
  • Have higher fees than index funds.
  • Rely on a team of live portfolio managers to make investment decisions.
  • Follow an active investment strategy and may adjust holdings based on how the market is performing.

The performance of index funds is relatively predictable, while the performance of actively managed funds tends to be less so. While index funds seek market-average returns, actively managed funds try to outperform the market.

It's worth noting that while index funds have consistently beaten actively managed funds in terms of performance, actively managed funds are still more popular.

Benefits of Investing in Index Funds

Low Fees

Among the top significant benefits of investing in index funds is the low fees associated with them. Index funds are passively managed, which means they require less research and analysis compared to actively managed mutual funds.

As a result, index funds charge lower fees, making them an attractive investment option.


Index funds provide broad market exposure by holding all (or a representative sample) of the securities in a specific index. This helps to minimize the risk of losing some or all of your money. By diversifying your portfolio, you can spread your investment across multiple stocks, reducing the impact of any one stock's performance on your overall portfolio.

Low Risk

Index funds are highly diversified, which helps to lower the risk of investing. They are also less volatile than individual stocks, which can be subject to large price swings. By investing in index funds, you can benefit from the stability of the market while minimizing your risk.

Tax Advantages

Index funds generate less taxable income than other types of mutual funds. This is because they have lower turnover rates and are less likely to sell securities at a profit. By investing in index funds, you can benefit from tax-efficient investing and potentially reduce your tax bill.

No Bias Investing

Index funds are not influenced by the biases of fund managers, who may have personal preferences or beliefs that affect their investment decisions. By investing in index funds, you can benefit from a more objective investment strategy that is not influenced by personal biases.

Potential for Long-Term Growth

Historically, index funds have outperformed other types of mutual funds over the long term. This is because they aim to match the performance of a designated index, which has a proven track record of growth.

By investing in index funds, you can benefit from the potential for long-term growth and potentially earn higher returns on your investment.

Lack of Flexibility

An index fund may have less flexibility than a non-index fund to react to price declines in the securities in the index. This lack of flexibility can lead to underperformance and potentially result in losses.

Tracking Error

An index fund may not perfectly track its index. For example, a fund may only invest in a sampling of the securities in the market index, in which case the fund's performance may be less likely to match the index.

This tracking error can lead to underperformance and potentially result in losses.


An index fund may underperform its index because of fees and expenses, trading costs, and tracking error. This underperformance can lead to lower returns on your investment.

Lack of Downside Protection

Investing in an index fund leaves you completely vulnerable to market corrections and crashes when you have a lot of exposure to stock index funds. This lack of downside protection can lead to significant losses.

Concentration Risk

Some indexes are heavily concentrated in certain sectors, such as technology, which can lead to increased risk. This concentration risk can lead to losses if the sector experiences a downturn.

Governance Risk

Index funds may invest in companies with poor governance practices, which can lead to reputational and financial risks. This governance risk can lead to losses if the company experiences a scandal or other negative event.

Tax Inefficiency

Index funds can be tax-inefficient due to capital gains distributions, which can result in unexpected tax bills. This tax inefficiency can erode your returns and potentially result in losses.

Popular Index Funds

Here are some of the most popular index funds available to investors:

  • Fidelity ZERO Large Cap Index (FNILX)
  • Vanguard S&P 500 ETF (VOO)
  • SPDR S&P 500 ETF Trust (SPY)
  • iShares Core S&P 500 ETF (IVV)
  • Schwab S&P 500 Index Fund (SWPPX)
  • Shelton NASDAQ-100 Index Direct (NASDX)
  • Invesco QQQ Trust ETF (QQQ)
  • Vanguard Russell 2000 ETF (VTWO)

These index funds offer low-cost, diversified exposure to the stock market, making them an excellent choice for long-term investors. The S&P 500 is one of the most popular indexes, and many of the funds listed above track this index.

Other popular indexes include the Nasdaq Composite and the Russell 2000.

Choosing the Right Index Fund

When choosing an index fund, there are several factors to consider, including expense ratios, minimum investments, and investment goals. Here are some steps to help you choose the right index fund for your investment goals:

1. Determine your investment goals: Before you start investing in index funds, it's essential to know what you want your money to do for you. If you're looking to make a lot of money quickly and are willing to take a lot of risk, you may be more interested in individual stocks or even cryptocurrency. But if you're looking to let your money grow slowly over time, particularly if you're saving for retirement, index funds may be a great investment for your portfolio.

2. Research index funds: Once you know what index you want to track, it's time to look at the actual index funds you'll be investing in. When you're investigating an index fund, consider several factors, including company size and capitalization, location, business sector, and fund expenses.

3. Choose the right fund for your index: If you have more than one index fund option for your chosen index, you'll want to ask some basic questions. Which index fund most closely tracks the performance of the index? Which index fund has the lowest costs? Are there any limitations or restrictions on an index fund that prevent you from investing in it? And does the fund provider have other index funds that you're also interested in using? The answers to those questions should make it easier to pick the right index fund for you.

4. Buy index fund shares: You can open a brokerage account that allows you to buy and sell shares of the index fund you're interested in. Alternatively, you can typically open an account directly with the mutual fund company that offers the fund.

Benefits of Index Funds

Low-cost index funds are generally the smartest investment most people can make. When you buy an index fund, you get a diversified selection of securities in one easy, low-cost investment. Vanguard is a popular provider of index funds, and they offer a wide range of low-cost index mutual funds and ETFs.

Why Fund Performance Matters When Investing in Index Funds

When investing in index funds, it's essential to pay attention to fund performance. This refers to how well a fund is doing compared to its benchmark index.

If a fund consistently underperforms its benchmark, it may not be worth investing in.

On the other hand, if a fund consistently outperforms its benchmark, it may be a good investment choice.

However, it's important to keep in mind that past performance is not a guarantee of future success.

It's also important to consider the fees associated with the fund, as high fees can eat into any potential gains.

By monitoring fund performance and fees, investors can make informed decisions when selecting index funds for their portfolio.

Performance and Tracking

Investing in index funds has become increasingly popular in recent years due to their low fees and ease of use. However, it's essential to understand how to track the performance of an index fund and what factors to keep in mind when choosing one.

Tracking the Performance of an Index Fund

To track the performance of an index fund, follow these steps:

1. Choose the index you want to track: An index fund tracks a market index, such as the S&P 500 or the Dow Jones Industrial Average. You need to know which market index you want your index fund to track before you invest.

2. Select a fund that tracks your chosen index: Once you've chosen an index, you can find several index funds that track it. For popular indexes like the S&P 500, you might have a dozen or more choices all tracking the same index.

3. Buy shares of the index fund: After you have chosen the index fund that tracks your selected index, you can buy shares of that index fund.

4. Monitor the performance of the index fund: Your index fund should mirror the performance of the underlying index. To check, look at the index fund's returns on a regular basis.

Factors to Consider When Choosing an Index Fund

When investigating an index fund, consider the following factors:

  • Company size and capitalization: Index funds can track small, medium-sized, or large companies (also known as small-, mid-, or large-cap indexes).
  • Tracking error: An index fund may not perfectly track its index. For example, a fund may only invest in a sampling of the securities in the market index, in which case the fund's performance may be less likely to match the index.
  • Underperformance: An index fund may underperform its index because of fees and expenses, trading costs, and tracking error.
  • Expenses: Before investing in any fund, carefully read all of the fund's available information, including fees and expenses.

The Impact of Fees and Expenses

Fees and expenses can have a significant impact on the returns of an index fund. Here are some key points to consider:

  • Expense ratio: This is one of the main costs of an index fund. It is a fee that is subtracted from each fund shareholder's returns as a percentage of their overall investment. Many index funds offer fees of less than 0.4%, whereas active funds often charge fees of more than 0.77%. The difference in fees can have a large effect on overall returns.
  • Tax-cost ratio: In addition to paying fees, owning the fund may trigger capital gains taxes if held outside tax-advantaged accounts, such as a 401(k) or an IRA. Like the expense ratio, these taxes can take a bite out of investment returns.
  • Impact on overall performance: Expense ratios directly impact the overall performance of a fund. Actively managed funds, with their often-higher expense ratios, are automatically at a disadvantage to index funds and struggle to keep up with their benchmarks in terms of overall return.
  • Lower fees: Index funds have lower fees than actively managed funds. Cheap index funds often cost less than 1%, with some firms offering even lower expense ratios of 0.05% or less. This reduction in the cost of fund management could mean lower overall costs to shareholders.
  • Advice from experts: According to Warren Buffett, low-cost index funds are the smartest investment most people can make. He advises both large and small investors to stick with low-cost index funds.

Portfolio Rebalancing

Investing in index funds has become increasingly popular due to their low fees and ability to match market performance. However, please understand the best practices for rebalancing your portfolio to ensure that it remains aligned with your investment goals.

Here are some tips for rebalancing your portfolio when investing in index funds.

Determining Your Desired Asset Allocation

The first step in rebalancing your portfolio is to determine your desired asset allocation. This involves constructing a portfolio that fits your individual risk tolerance and investment goals. You should have a mix of investment assets, usually stocks and bonds, appropriate for your risk tolerance and investment goals.

Choosing Funds with Automatic Rebalancing

The easiest way to rebalance your DIY portfolio is to choose funds whose managers do the rebalancing for you. Target-date funds are an example of a type of fund that is rebalanced automatically. This can save you time and effort in managing your portfolio.

Being Aware of Taxes

When rebalancing an investment portfolio, please be aware of the taxes you will incur when selling profitable investments. One way to minimize taxes is to focus on tax-advantaged accounts and rebalance with portfolio cash flows.

Rebalancing Based on Your Investments

You can rebalance your portfolio based either on the calendar or on your investments. Many financial experts recommend that investors rebalance their portfolios on a regular basis, such as every six or twelve months.

However, it's important not to rebalance too often, as this can result in higher costs and panic transactions.

Minimizing Transaction Fees and Taxes

You should be mindful of costs when rebalancing your portfolio. One way to do this is to focus on tax-advantaged accounts and rebalance with portfolio cash flows. This can help to minimize transaction fees and taxes.

Reviewing Your Investments

When you rebalance, you'll also need to review the investments within each asset allocation category. If any of these investments are out of alignment with your investment goals, you'll need to make changes to bring them back to their original allocation within the asset category.

Common Misconceptions About Index Funds

It is fundamental to understand some common misconceptions about index funds to make informed decisions about investing in them.

All Index Funds Are the Same

This is a myth. While index funds tracking similar assets should perform more or less equally, indexing has expanded to include other assets such as bonds, foreign stocks, small companies, and other investments, so the funds are not all alike.

Index Funds Won't Beat the Market

This is another myth. While index funds are not designed to beat the market, they are designed to match it. In fact, because index funds feature lower expenses, they tend to beat the majority of non-indexed, actively managed rivals over time.

ETFs Are the Only Type of Index Fund

This is a myth. Unlisted index funds have been available for many years but have gone under the radar of some investors. These funds allow you to hold a variety of shares in a single investment, but rather than buying through the ASX, you deal with the product issuer.

Index Investing Produces Average Results

This is a common misconception. While it is true that index investing is designed to match the market, many people mistakenly believe that it produces average results. In reality, index investing can produce above-average results because it eliminates the risk of underperformance that comes with active management.

This is a common misconception. While it is true that cash flows into and out of index funds impact the price of market securities to some extent, the impact is relatively small and short-lived.

Concluding thoughts

So, we've talked about benchmarking and how it relates to investing in index funds. We've covered the basics of understanding index funds, the benefits of investing in them, popular index funds, performance and tracking, and portfolio rebalancing. But let's take a step back and think about the bigger picture.

When we invest in index funds, we're essentially buying a piece of the market. We're putting our money into a basket of stocks that represent a specific index, like the S&P 500. But what does that really mean? Are we just blindly following the market, hoping for the best?

Here's where things get interesting. Benchmarking can actually be a tool for change. When we measure ourselves against a benchmark, we're setting a standard for ourselves. We're saying, This is where we are now, and this is where we want to be. It's a way of setting goals and pushing ourselves to do better.

But it's not just about beating the benchmark. It's about understanding why we're investing in the first place. Are we saving for retirement? Trying to build wealth for our families? Supporting a cause we believe in? Whatever our reasons, we need to stay true to them and use benchmarking as a tool to help us get there.

So, as you consider investing in index funds, don't just focus on the numbers. Think about what you're trying to achieve and why. Use benchmarking as a way to measure your progress and set goals for yourself. And remember, investing is a long-term game. It's not about getting rich quick, but about building a solid foundation for your future.

In the end, benchmarking is just a small piece of the puzzle. It's up to us to use it wisely and keep our eyes on the bigger picture. Happy investing!
