For years, “UK equities” was a hard sell for global allocators. London’s Blue-Chip index trailed the S&P 500 and many emerging markets through much of the post-2010 cycle. In 2026, the picture has changed. The FTSE 100 broke 10,000 points for the first time in its history (Yahoo Finance, Morningstar UK) and has held near record territory through the spring. Trading Economics data showed the index around 10,297 on 13 May 2026.

According to research commentary cited in major financial media, global investors have been rebuilding positions in UK blue chips, drawn by attractive valuations, record forecast dividends (£88bn ordinary distributions in 2026, per AJ Bell) and exposure to global themes such as energy, Mining, healthcare and defence. This guide explains how the FTSE 100 works, why it is back on the global radar, and what UK and international investors are watching.

Key takeaways

  • The FTSE 100 tracks the 100 largest UK-listed companies by Market Capitalisation (LSEG, FTSE Russell).
  • Around three-quarters of FTSE 100 Revenue is earned outside the UK (LSEG).
  • Forecast £88bn Ordinary Dividends in 2026, with HSBC alone at around £10.7bn (AJ Bell).
  • Forward Dividend Yield around 3.4% in 2026 (AJ Bell), well above S&P 500 norms.
  • Sector mix is dominated by financials, energy, materials, healthcare, consumer staples and industrials (FTSE Russell).
  • Global investors have rotated into UK equities in 2026 amid valuation gaps.

What is the FTSE 100?

The FTSE 100 is the index of the 100 largest companies by market capitalisation listed on the London Stock Exchange. It is calculated and maintained by FTSE Russell and is widely used as a benchmark for UK blue-chip Equity performance. Constituents are reviewed quarterly.

Despite its London listing, the FTSE 100 is far more global than its name suggests. According to LSEG and FTSE Russell data, around three-quarters of FTSE 100 revenues are generated outside the UK. That makes the index a play on the global economy with a UK currency translation layer.

Why global investors are back in 2026

Several drivers have brought UK blue chips back onto allocators’ radars:

  • Relative valuation: UK blue chips have traded on lower price-to-Earnings multiples than US peers, leaving more Cash Flow available to shareholders.
  • Record dividends: AJ Bell forecasts FTSE 100 ordinary dividends at £88bn in 2026 — a record.
  • Sector mix: Energy, miners, banks and defence — all favoured themes in 2026 — have heavy weightings in the FTSE 100.
  • Sterling and global earnings: A weaker pound for parts of the cycle has supported translated overseas earnings.
  • Rotation: Some global investors have rotated from richly valued US large-cap technology into perceived value markets.
  • Headline momentum: Crossing 10,000 points has reset perceptions of the UK market.

How the index is structured

The FTSE 100 is market-cap weighted, with quarterly reviews to manage promotion and relegation between the FTSE 100 and FTSE 250. The index includes a mix of UK-headquartered and UK-listed global businesses.

Sector composition is dominated by:

  • Financials (banks, insurers, asset managers): HSBC, Barclays, Lloyds, NatWest, Standard Chartered, Legal & General, Aviva, LSEG.
  • Energy: Shell, BP.
  • Materials: Rio Tinto, Glencore, Anglo American, Antofagasta.
  • Healthcare: AstraZeneca, GSK.
  • Consumer staples: Unilever, Diageo, Tesco, Sainsbury’s.
  • Industrials: Rolls-Royce, BAE Systems.
  • Communications and data:
  • Utilities: National Grid.

How to invest in the FTSE 100

UK investors typically access the index in one of three ways:

  1. Passive tracker funds or ETFs for low-cost, diversified exposure.
  2. Individual blue-chip shares for targeted exposure to specific themes.
  3. Actively managed UK equity funds, where managers select shares from the index.

Tax wrappers such as a Stocks and Shares ISA or a SIPP allow UK investors to hold FTSE 100 shares with favourable tax treatment within annual allowances set by HMRC. Tax rules can change and depend on individual circumstances.

International investors can also access the FTSE 100 via UK-listed ETFs, US-listed equivalents, or directly through brokerages with access to the London market.

What investors are watching in 2026

  • HSBC: The single largest dividend payer in the FTSE 100, with around £10.7bn forecast (AJ Bell).
  • Shell and BP: Major contributors to FTSE 100 dividends and a key barometer of energy markets.
  • AstraZeneca: One of the FTSE 100’s largest companies and a defensive growth name.
  • Rolls-Royce and BAE Systems: Re-rated industrials with strong cash flow and order backlogs.
  • Miners: Rio Tinto, Glencore, Anglo American and Antofagasta have led recent gains.
  • Insurers: Legal & General (~9% yield, indieinvestor.co.uk) and Aviva (~6.1%) remain on income watchlists.
  • RELX and LSEG: Data-rich, recurring-revenue businesses representing the FTSE 100’s underrated technology exposure.

What this means for UK investors

A renewed global interest in UK blue chips may have several practical implications for UK investors: higher Demand for the index can support prices, attract corporate activity (including M&A), and contribute to a positive feedback loop with global Capital. None of these factors guarantees future returns.

A sensible approach for many UK investors is to build diversified exposure to the FTSE 100 — perhaps through a tracker — while using selected individual shares to express specific themes such as income, defence, healthcare or commodities. Tax-efficient wrappers and a long-term horizon remain core to most successful approaches.

Risks to watch

  • Commodity and energy Volatility: Big swings can rapidly affect FTSE 100 earnings.
  • Policy and political risk: UK fiscal and regulatory changes can move sectors.
  • Sterling volatility: A stronger pound erodes overseas earnings.
  • Concentration: A small number of giants drive much of the index.
  • Global slowdown: A sharp downturn in China or the US would weigh on FTSE 100 names.
  • Re-rating risk: Recent winners can give back gains if results disappoint.
