FTSE 100 ETFs: Tracking the UK Index

So, is a FTSE 100 ETF a good investment? That depends on what you are trying to achieve. Putting all of your eggs in a UK-shaped basket is probably not a great idea, but as part of a broader portfolio that spreads your investments geographically, then it’s a perfectly fine way of grabbing a slice of the UK market.

Representing the 100 largest companies listed on the London Stock Exchange, the FTSE 100 is often used as the bellwether for the overall UK economy. These companies span various sectors, from finance and healthcare to technology and consumer goods, making the index a (somewhat) diversified snapshot of the UK market.

FTSE 100 ETFs aim to replicate the performance of the FTSE 100 index, providing you with a diversified portfolio in a single trade. If you feel strongly that UK stocks will outperform, and that your global equity ETF doesn’t hold a big enough piece of the UK market, then a FTSE 100 ETF is an easy way to increase your UK exposure.

VUKE vs ISF vs HUKX

The best three options are offered by Vanguard (VUKE), iShares (ISF) and HSBC (HUKX). As with most big index trackers of major markets, which you choose makes very little difference.

Their respective long-term performance is pretty much the same, which you’d expect. These ETFs track the FTSE 100 index through physical replication, which means they actually buy the shares of the companies that make up the index. So the performance of these ETFs is very close to the index itself – generally within a few percentage points over the long term.

Does the size of the ETF matter? In this case, not really as none of these are what you’d call small. They are all popular enough to ensure enough liquidity, meaning there will be no issue buying and selling when the need arises.

So which do you choose? It may simply come down to what is offered by your platform. This is especially relevant if you are a Vanguard customer, as you can only invest in Vanguard products. In this case, you can rest easy knowing you are not missing out on anything.

Why Invest in a UK Index Tracker?

Diversification (but not much)

• Broad UK Large-Cap Exposure: FTSE 100 ETFs provide exposure to the top 100 companies listed on the London Stock Exchange, offering a diversified investment in a single trade.
• Sector Diversification: These ETFs cover multiple sectors such as finance, healthcare, and technology, reducing sector-specific risks.
• Indirect Global Reach: Many FTSE 100 companies are multinational corporations, providing indirect exposure to global markets.

Cost-Efficiency

• Low Expense Ratios: FTSE 100 ETFs generally have lower expense ratios compared to actively managed funds. Aim to pay less than 0.1%.
• No Entry/Exit Fees: Most ETFs do not charge entry or exit fees, making them one of the cheapest ways to invest.

Investment Strategy Alignment

• Overweight UK: If you feel strongly that the UK will outperform the global market, then an extra chunk of the FTSE 100 in your globally diverse portfolio is a good way to capture that.
• Dividend Income: The distributing versions of these ETFs furnish you with the dividends paid by the FTSE 100 companies, making them suitable for income-seeking investors.
• Tax Efficiency: Like other exchange-traded funds, FTSE 100 ETFs can be held within an ISA or SIPP. See here for more on the tax treatment of ETFs in the UK.

Risk Management

• Lower Volatility: The diversification benefits often result in lower volatility compared to investing in individual stocks.
• Liquidity: The ETFs covered here are large and popular with high trading volumes, ensuring that you can easily enter or exit positions.

Flexibility and Accessibility

• Trading Hours: ETFs can be traded throughout the market day, offering flexibility.
• Accessibility: Available through all major platforms, making it easy for investors to add them to their portfolios.

Accumulation vs. Distributing ETFs

You may have noticed that there are different versions of the same funds listed above. Often people

• Accumulation ETFs: These automatically reinvest the dividends back into the fund, increasing the net asset value of the ETF units you hold. Ideal for investors focused on capital growth.
• Distributing ETFs: These pay out dividends directly to investors, providing an income stream. Suitable for those who require regular income from their investments.
• Dividend Tax: Bear in mind that you are liable for dividend tax regardless of whether you receive the payment or it is automatically reinvested.

Example: VUKE vs VUKG

The two versions of the Vanguard FTSE 100 UCITS ETF differ only in their treatment of dividends: VUKE is a distributing ETF, which means it pays the dividends directly to investors; VUKG is an accumulating ETF, automatically reinvesting dividends back into the fund.

Dividend Yields and Income

Benefits of Dividends in Total Returns

• Income Stream: Dividends provide a consistent income stream, which can be especially beneficial for retirees or those seeking regular income.
• Compounding Effect: Reinvesting dividends can significantly enhance the compounding effect, leading to higher long-term returns.
• Market Volatility: Dividends can offer a cushion during market downturns, providing a more stable return profile.

Comparison of Dividend Yields Among Top FTSE 100 ETFs

• Vanguard FTSE 100 ETF: Dividend yield of 3.82%
• iShares Core FTSE 100 ETF: Dividend yield of 3.75%
• HSBC FTSE 100 ETF: Dividend yield of 3.38%

Home Bias: An Overlooked Risk for UK Investors

What is Home Bias?

Home bias refers to the tendency of investors to disproportionately allocate their investment capital to domestic assets, often overlooking opportunities in foreign markets. For UK investors, this could mean a portfolio heavily skewed towards UK-based assets, such as FTSE 100 ETFs.

Psychological Factors

• Familiarity: Investors often feel more comfortable investing in companies and markets they are familiar with.
• Perceived Control: The illusion of better control and understanding of local markets can contribute to home bias.
• Information Availability: Easier access to news and updates about local companies can make domestic investments seem more attractive.

Implications for FTSE 100 ETFs

• Overexposure: Investing predominantly in FTSE 100 ETFs can lead to a lack of diversification, exposing you to localised economic risks.
• Missed Opportunities: By focusing solely on domestic assets, you may miss out on potentially lucrative investment opportunities in other markets.
• Currency Risks: A portfolio heavily weighted in GBP assets can expose you to currency risks, especially during times of economic uncertainty in the UK.

How to Mitigate Home Bias

• Global Diversification: Consider allocating the bulk of your portfolio to international assets.
• Asset Allocation: Rebalance your portfolio periodically to ensure a healthy mix of domestic and international assets.
• Consult a Financial Advisor: Seek professional advice to objectively assess your investment strategy and potential home bias.

Conclusion

The UK makes up about 4% of the global market, and a portfolio that is properly diversified geographically should match this. Remember, a lot of your non-investment capital is tied up in your home country – your property, job, business etc – so you are already very exposed to local economic downturns.

Bearing all this in mind, the reasons for wanting exposure to the biggest UK companies are personal to you. Just make sure they are the right reasons.
