What Is a Tracker Fund?

This guide explains how tracker funds work, what they can and cannot do and what you should consider before investing. It is for educational purposes only and does not constitute personal financial advice. If you are unsure whether a tracker fund suits your circumstances, consider speaking with a qualified financial adviser.

What is a tracker fund?

A tracker fund is an investment fund designed to replicate the performance of a specific market index. Instead of a fund manager picking individual shares they believe will outperform the market, the fund simply holds the same securities as its chosen benchmark, in similar proportions.

For example, a fund tracking the FTSE 100 would hold shares in the 100 largest companies listed on the London Stock Exchange. If the FTSE 100 rises by 5%, the fund aims to deliver a similar return, minus costs. If the index falls by 5%, the fund’s value would typically fall by roughly the same amount.

This approach is often called passive investing because the fund follows predetermined rules rather than relying on active decision-making by managers.

Tracker fund vs index fund: Are they the same?

In everyday use, the terms tracker fund and index fund are interchangeable. Both describe funds that aim to mirror a market index. You may also hear them called passively managed funds.

The terminology used can vary by provider. Some call them tracker funds, others prefer index funds. The underlying principle remains identical: follow an index, do not try to beat it.

How do tracker funds work?

Tracker funds aim to replicate their benchmark index through one of two main methods.

Full replication means the fund buys every security in the index at the same weighting. A FTSE 100 tracker using full replication would own all 100 constituent shares. When the index rebalances, perhaps removing one company and adding another, the fund adjusts its holdings accordingly.

Sampling involves holding a representative selection of securities rather than every single one. This approach is common when an index contains hundreds or thousands of constituents. The fund manager selects securities that collectively behave similarly to the full index. Sampling can reduce trading costs but may introduce slight differences between fund performance and index performance.

These differences between a fund’s returns and its benchmark’s returns are called tracking error. Even well-managed tracker funds rarely match their index perfectly. Costs, timing of trades and sampling decisions all contribute to small deviations.

What indices can tracker funds follow?

UK investors have access to tracker funds covering numerous indices. Some of the most common include:

UK Indices:

• FTSE 100: The 100 largest companies by market capitalisation on the London Stock Exchange

• FTSE 250: The next 250 largest UK companies after the FTSE 100

• FTSE All-Share: A broader index combining the FTSE 100, FTSE 250 and smaller companies

International Indices:

• S&P 500: 500 large publicly traded US companies

• MSCI World: Large and mid-cap companies across developed markets globally

• MSCI Emerging Markets: Companies in developing economies

FTSE 100 tracker funds remain among the most popular choices for UK investors seeking domestic equity exposure.

Types of tracker funds available in the UK

Tracker funds come in different structures. Understanding these can help you choose an appropriate option for your situation.

Index funds vs ETFs

Index funds in the UK are typically structured as open-ended investment companies or unit trusts. You buy and sell units directly from the fund provider at a price calculated once daily, based on the net asset value of the fund’s holdings.

Exchange-traded funds, known as ETFs, are also tracker funds but trade on stock exchanges like ordinary shares. You can buy and sell ETFs throughout the trading day at market prices, which fluctuate based on supply and demand.

Both structures can track the same indices effectively. Your choice may depend on how you prefer to invest and the platform you use.

To understand where tracker funds fit within the broader investment landscape, it helps to know what mutual funds are. A mutual fund is simply a collective investment that pools money from multiple investors. Both index funds and actively managed funds are types of mutual funds.

Similarly, understanding what an equity fund is can provide context. An equity fund invests primarily in company shares rather than bonds or other assets. Most tracker funds tracking indices like the FTSE 100 are equity funds.

Potential benefits of tracker funds

Tracker funds can fall in value and you may get back less than you invest.

Tracker funds have gained popularity for several reasons, though none guarantee positive outcomes.

Lower costs represent a significant potential advantage. Because tracker funds do not require teams of analysts researching individual shares, their operating expenses tend to be lower than actively managed alternatives. Over long periods, even small differences in charges can affect your returns.

Diversification comes built into many tracker funds. A single investment in a FTSE All-Share tracker gives you exposure to hundreds of companies across various sectors. This spreads your risk compared to holding individual shares, though it does not eliminate risk.

Simplicity appeals to many investors. You do not need to evaluate fund manager skill or predict which sectors will outperform. The fund’s objective is transparent: match the index.

Transparency means you generally know what the fund holds. The constituents of major indices are publicly available, so you can see which companies your money is invested in.

Limitations and risks to consider

Tracker funds carry investment risk, and your capital is at risk when investing. Past performance is not a reliable guide to future results.

Market risk means if the index falls, so does your investment. A FTSE 100 tracker will not protect you during a market downturn. When the index drops 20%, your investment will likely fall by a similar amount.

No opportunity to outperform is the flip side of passive investing. By design, a tracker fund cannot beat its benchmark, only match it minus costs. Some investors prefer the possibility of outperformance that active management can offer, even if many active funds fail to deliver it consistently.

Tracking error can cause your returns to differ from the index. Costs, sampling methods and operational factors mean no tracker fund perfectly mirrors its benchmark.

Concentration risk exists within some indices. The FTSE 100, for instance, has significant weightings towards certain sectors like financial services, energy and healthcare. A tracker following this index inherits that concentration.

Currency risk applies to funds tracking international indices. If you invest in an S&P 500 tracker, your returns depend partly on movements between the UK pound and the US dollar.

Tracker funds vs actively managed funds

Active fund managers conduct research and make judgements about which securities to buy, hold or sell. They aim to deliver returns above their benchmark. However, achieving consistent outperformance after costs is difficult, and many active funds underperform their benchmarks over longer periods.

Tracker funds accept average market returns. For some investors, capturing the broad market return at low cost represents a sensible approach. Others prefer the potential, even if uncertain, of active management.

Neither approach is inherently superior. Your choice depends on your goals, beliefs about markets and tolerance for different types of risk.

Costs and charges explained

Understanding costs matters because charges directly reduce your returns.

The ongoing charges figure, sometimes called the total expense ratio, represents the annual percentage deducted from your investment to cover fund operating expenses. For UK tracker funds, this figure typically ranges from 0.06% to 0.50% annually. Actively managed funds often charge between 0.50% and 1.50% or more.

Platform fees may apply when you invest through an investment platform or stockbroker. These vary by provider and can be flat fees, percentage charges or both.

Dealing charges apply when buying or selling ETFs, similar to purchasing ordinary shares. Some platforms offer commission-free trading on certain products.

Bid-offer spreads represent the difference between buying and selling prices. This gap is usually narrow for popular tracker funds but still constitutes a cost.

How to invest in tracker funds in the UK

If you decide tracker funds suit your circumstances, here is a general overview of how to invest in UK index funds.

• Choose a platform. Options include investment platforms, stockbrokers, robo-advisers and some banks. Consider the range of funds available, platform fees and ease of use.

• Decide on a tax wrapper. Investing through an Individual Savings Account (ISA) or a Self-Invested Personal Pension (SIPP) can provide tax advantages. ISAs shield gains and income from tax up to annual contribution limits. SIPPs offer pension tax relief but lock away your money until retirement age. Tax treatment depends on your individual circumstances and tax rules may change.

• Select your fund or funds. Consider which index aligns with your objectives, the fund’s ongoing charges figure, its tracking error history and whether you prefer an index fund or ETF structure.

• Consider how much and how often to invest. Many platforms allow regular contributions, which can help smooth out the effects of market volatility. This does not guarantee profits or protect against losses.

Remember, choosing investments involves risk and what suits one person may not suit another. If you are uncertain, consider seeking guidance from a qualified financial adviser.

Key questions to ask before investing

Before committing money to any tracker fund, consider these questions:

• What is my investment timeframe? Equity tracker funds generally suit longer-term investors who can ride out market fluctuations. If you need your money within a few years, a stock market investment may carry uncomfortable levels of short-term risk.

• How would I feel if my investment fell by 20% or more? Market downturns happen. Honest assessment of your risk tolerance can prevent panic selling at the worst times.

• Do I understand what the fund invests in? Reading the fund’s key investor information document reveals its objectives, benchmark, costs and risks.

• What are the total costs? Combine the fund’s ongoing charges figure with any platform fees and dealing costs to understand the full picture.

• Does this fund fit within a broader plan? Most financial professionals suggest diversification across different asset types, not just within equities.

• Have I considered seeking advice? For complex situations or larger sums, professional financial advice can prove valuable.

Summary

A tracker fund is an investment fund that aims to replicate the performance of a market index such as the FTSE 100, FTSE 250 or FTSE All-Share. Rather than trying to beat the market, these funds accept market returns in exchange for typically lower costs and greater simplicity.

The most suitable tracker fund for a UK investor will depend on individual circumstances, objectives and risk tolerance. There is no universally correct answer.

Key points to remember:

• Tracker funds aim to match, not beat, their benchmark index.

• They tend to have lower ongoing charges than actively managed funds.

• Your capital is at risk and values can fall as well as rise.

• Past performance does not guarantee future results.

• Different structures exist, including index funds and ETFs.

• Costs, tracking error and the index chosen all affect outcomes.
