Key Takeaways

  • FTSE tracks top UK companies on London Stock Exchange.
  • FTSE 100 includes largest 100 firms by market cap.
  • Indices are market-cap weighted for performance tracking.

What is Financial Times Stock Exchange Group (FTSE)?

The Financial Times Stock Exchange Group (FTSE) is a provider of stock market indices, best known for managing the FTSE 100 and other UK market benchmarks that track companies listed on the London Stock Exchange. These indices serve as essential tools for investors monitoring the performance of large-cap and mid-cap stocks in the UK equity market.

FTSE indices use a market capitalization-weighted approach to reflect the aggregated value of constituent companies, influencing investment decisions and portfolio construction strategies such as factor investing.

Key Characteristics

FTSE indices have distinct features that make them valuable benchmarks for various market participants:

  • Market Coverage: The FTSE 100 represents the largest 100 companies by market capitalization, while the FTSE 250 covers mid-cap stocks, together forming the FTSE 350.
  • Index Calculation: Weights are based on free float market capitalization, adjusting for shares available to public investors, similar to principles used in A shares.
  • Quarterly Review: Constituents are reviewed every quarter to ensure the indices reflect current market capitalization and liquidity criteria.
  • Global Impact: The FTSE 100 includes multinational companies influencing not only UK but also global equity markets.

How It Works

FTSE indices calculate their values by multiplying each constituent's share price by the number of shares available for public trading, adjusted by a free float factor. This method ensures that larger companies have a proportionally bigger impact on index movements.

The indices are updated in real-time during market hours, providing investors with timely data to gauge market trends, manage idiosyncratic risk, and make informed decisions. This dynamic calculation is crucial for active market participants and fund managers tracking UK equities.

Examples and Use Cases

FTSE indices offer practical benchmarks and investment opportunities across multiple sectors and company sizes:

  • Large-cap exposure: Investors seeking stability often focus on the FTSE 100, which includes global companies such as HSBC and BP.
  • Mid-cap opportunities: The FTSE 250 is favored for more domestically focused companies like easyJet and Dunelm, offering growth potential.
  • ETF benchmark: Many exchange-traded funds (ETFs) track FTSE indices, providing diversified access to UK equities; explore our best ETFs guide for insights.
