Best global ETFs to watch

What are ETFs?

Exchange Traded Funds (ETFs) are investment funds that trade on a stock exchange just like individual stocks, while holding a basket of underlying assets such as stocks, bonds, commodities or a combination thereof. They have revolutionised investing by providing accessible, cost-effective exposure to diversified portfolios across hundreds of different themes.

If you are looking to get started with ETF investing, you can open a stocks and shares ISA or share dealing account with us and access a wide range of global ETFs. For more on how ETFs work in practice, see our guides on what are ETFs and how to invest in ETFs.

How ETFs Work

ETFs are designed to track the performance of a specific index, sector, commodity or investment strategy. Unlike mutual funds, which are priced once a day at market close, ETFs trade throughout the day at market prices. This structure combines the diversification benefits of mutual funds with the flexibility and liquidity of individual stocks.

Key features include:

• Passive management — many ETFs passively track an index, eliminating the need for active fund management and reducing costs
• Transparency — holdings are typically disclosed daily, allowing investors to see exactly what they own
• Tax efficiency — ETFs generally generate fewer taxable events than mutual funds due to their creation and redemption process
• Fractional ownership — investors can gain exposure to hundreds or thousands of securities through a single purchase

ETF diversification 
benefits

Diversification is often viewed as key to sound risk management. By spreading investments across different asset classes, geographic regions and sectors, investors can significantly reduce portfolio risk without necessarily sacrificing returns.

The classic investment principle of not putting all your eggs in one basket is more relevant than ever. Consider Japan's stock market, which peaked in 1989 and still hasn't fully recovered decades later. Investors who concentrated their portfolios in Japanese equities experienced devastating long-term losses. Similarly, UK investors heavily weighted toward domestic oil, commodity and financial companies faced severe challenges during the 2008 Global Financial Crisis.

Key types of diversification include:

• Geographic diversification — currently, US stocks represent more than 60% of global market capitalisation, but this hasn't always been the case. In the 1980s, Japan dominated global markets. Future market leaders may emerge from China, India or other developing economies
• Sector diversification — no single sector consistently outperforms. Technology has dominated in recent decades, but energy, financials and healthcare have had their periods of leadership. ETFs provide easy access to multiple sectors simultaneously
• The Rule of 30 — traditional diversification wisdom suggests holding at least 30 individual positions to adequately diversify away company-specific risk. ETFs make this easy by providing exposure to hundreds or even thousands of securities in a single investment

Top global ETFs to watch

There are thousands of ETFs to consider, but the selection below has been chosen for their significant popularity among investors and constant media coverage. They represent a good starting point for your own research.

Amundi Prime All Country World UCITS ETF

The Amundi Prime All Country World UCITS ETF has become a popular choice for investors seeking global diversification due to its very low cost. With an expense ratio of just 0.07%, it is one of the cheapest global ETFs on the market. The fund tracks the Solactive GBS Global Markets Large & Mid Cap index, covering both developed and emerging markets, and has accumulated over $3.5 billion in assets under management. This ETF offers broad global exposure, making it particularly attractive for long-term buy-and-hold investors. The combination of comprehensive market coverage and rock-bottom fees positions it as an excellent core holding for portfolios of any size.

Vanguard FTSE All-World UCITS ETF

The Vanguard FTSE All-World UCITS remains one of the most popular and comprehensive global ETFs available to investors. With an expense ratio of 0.19%, it provides exposure to nearly 4,000 companies across 50 countries, offering exceptional diversification with a well-established track record and strong brand reputation. Having accumulated over $29 billion in assets under management, it stands as one of the most trusted global ETFs. The broad diversification inherent in this ETF offers protection against single-country downturns while providing exposure to global growth opportunities, including AI-driven US tech stocks and emerging market potential. However, investors should be aware of the US concentration bias and technology sector dominance that can increase volatility, and the fund has historically underperformed the S&P 500 over longer periods.

iShares Core MSCI World UCITS ETF

The iShares Core MSCI World UCITS ETF focuses exclusively on developed markets, providing exposure to roughly 1,500 companies within 23 developed countries, covering 85% of the listed equities in each country. With an expense ratio of 0.20% and approximately $130 billion in assets under management, this fund has established itself as a cornerstone holding for many institutional and retail portfolios. This ETF excludes emerging markets entirely, which reduces overall volatility and focuses investors exclusively on stable, established economies — ideal for those seeking developed-market exposure without the additional risks associated with emerging-market investments.

iShares Core S&P 500 UCITS ETF

While technically US-focused rather than global, the iShares Core S&P 500 UCITS ETF deserves a mention due to its popularity and the inherently global nature of its constituent companies. This ETF tracks the 500 largest US companies by market capitalisation with an expense ratio of just 0.03%, making it one of the most cost-effective ways to gain exposure to American blue-chip companies. The index has delivered average annual returns of 10.15% since 1957, establishing one of the strongest long-term track records in equity investing. Many S&P 500 companies generate significant international revenue — Apple, Microsoft and Coca-Cola all derive substantial portions of their revenues from overseas markets, creating a degree of international diversification.

Vanguard Total International Stock ETF

For investors seeking to complement their US holdings with international exposure, the Vanguard Total International Stock ETF stands out as a Morningstar Gold-rated pick. With an expense ratio of just 0.05% and holdings of over 8,000 international stocks from both developed and emerging markets, it offers exceptional breadth of diversification with no single company exceeding 2% of the portfolio weight. For investors who are overweight US stocks, this ETF provides comprehensive ex-US exposure in a single, highly liquid and cost-effective package — an ideal complement to US-focused holdings.

Invesco Physical Gold ETC

Gold remains a critical portfolio diversifier and inflation hedge, and the Invesco Physical Gold ETC offers one of the most direct ways to gain gold exposure. The structure is backed 1:1 by physical gold bullion with assets under management of approximately €22.5 billion as of July 2026. Gold prices surged to all-time highs above $3,500/oz earlier in 2026, before pulling back somewhat — global gold ETF AUM reached a record $669 billion in January 2026 before moderating to approximately $604 billion by May as flows slowed. The rationale for holding gold extends beyond recent price appreciation: it provides protection during periods of market stress, hedges against currency debasement and inflation, and historically exhibits low correlation with equities. Central banks have continued to accumulate gold at near-record levels, supporting long-term demand. For more on gold and commodity investing, see our gold trading guide.

Vanguard FTSE Emerging Markets ETF

For growth-oriented investors willing to accept higher risk, emerging markets may offer compelling opportunities for potentially superior long-term returns. The Vanguard FTSE Emerging Markets ETF provides this exposure with an expense ratio of 0.08%, investing in economies including China, Brazil, Taiwan, India and other developing nations. Top holdings include companies like Taiwan Semiconductor, Tencent and Alibaba, representing some of the most innovative and rapidly growing companies in the world. Despite a decade of underperformance relative to developed markets, emerging markets may be poised for a resurgence as global supply chains diversify and middle-class populations expand dramatically in India and Southeast Asia.

iShares UK Dividend UCITS ETF

For income-focused UK investors, the iShares UK Dividend UCITS ETF offers regular cash flow through a strategy that invests in the top 50 FTSE 350 companies with the highest dividend yields. Top holdings include well-established names like HSBC, Rio Tinto and Legal & General, all of which have histories of returning cash to shareholders. The fund's focus on income generation makes it particularly attractive for retirees or others seeking regular portfolio income rather than pure capital appreciation. Investors should be aware that dividends are never guaranteed, and cyclical companies can cut payouts during economic downturns.

Pros and cons of ETF investing

Like all investing strategies, ETF investing has its advantages and drawbacks.

Pros include cost efficiency — ETFs typically offer lower expense ratios than actively managed mutual funds, with many global ETFs charging between 0.03% and 0.20% annually compared to 1-2% for traditional mutual funds, a saving that compounds dramatically over decades. Liquidity and flexibility allow ETFs to be bought and sold throughout trading hours at market prices, giving greater control over entry and exit points. Diversification means a single global ETF can provide exposure to thousands of companies across dozens of countries. Tax advantages from the ETF structure minimise taxable distributions through in-kind redemptions. Transparency through daily disclosure of holdings allows investors to know exactly what they own. Accessibility with low share prices makes ETFs available to investors with limited capital.

Cons include trading costs — while expense ratios are low, frequent trading may incur brokerage commissions and bid-ask spreads that can erode returns. Tracking error means ETFs may not perfectly replicate their underlying index due to fees, trading costs and replication methodology. The ease of trading ETFs can lead to overtrading temptation and impulsive decisions. Concentration risk means some ETFs, particularly those tracking market-cap-weighted indices, can become heavily concentrated in a few large companies — the S&P 500 is heavily weighted toward mega-cap technology stocks. Diversification limitations mean that during market crises, correlations between asset classes often increase. And the lack of active management means passive ETFs cannot adapt to changing market conditions or avoid overvalued securities.

Building your ETF portfolio

The following is not financial advice. Everybody's personal situation is different and you may wish to seek professional advice. However, as a broad indication, many investors recommend a core-satellite strategy where 70-80% of your portfolio consists of broad market index ETFs (the core), with the remaining 20-30% in specialised ETFs targeting specific themes, sectors or strategies (the satellites).

Your core holdings might include the Vanguard FTSE All-World or Amundi Prime All Country World for comprehensive global exposure, while your satellite holdings might include a gold ETC for inflation protection, an emerging market ETF for growth potential, a dividend ETF for income, or sector-specific ETFs for tactical positions. You can also consider money market ETFs as a cash-like holding within your portfolio.

Your asset allocation should reflect both your time horizon and comfort with volatility. Aggressive portfolios suited for young investors with 30+ year horizons might consist of 90-100% global equity ETFs. Moderate portfolios for mid-career investors with 15-25 year horizons typically include 70-80% global equity ETFs, 10-20% bond ETFs and 5-10% in gold or alternative assets. Conservative portfolios for those near or in retirement generally hold 40-60% global equity ETFs, 30-40% bond ETFs, and 10-20% in gold, dividend stocks or defensive assets.

Common mistakes to avoid

Over-diversification through too many overlapping ETFs dilutes returns without additional diversification benefits. Chasing performance means last year's outperformers often become this year's underperformers. Even small fee differences compound significantly over decades, so ignoring costs is a costly mistake. Neglecting rebalancing means portfolios drift over time and should be reviewed periodically. Panic selling during market downturns locks in losses — market corrections are a normal part of long-term investing. Home country bias through overweighting domestic stocks increases concentration risk. For more on avoiding these mistakes, see our guide on how to pick stocks and how to invest in shares.

Past performance is not a reliable indicator of future results. The value of investments can fall as well as rise and you may get back less than you invest.
