Understanding FTSE Indices
The Financial Times Stock Exchange (FTSE) indices are the primary benchmarks for the UK stock market. When people say "the market is up," they are usually referring to the FTSE 100, which represents the 100 largest companies by market capitalization listed on the London Stock Exchange.
FTSE 100
Global conglomerates, stable dividends, lower growth.
FTSE 250
Mid-sized UK companies, domestic focus, higher historical growth.
Why Use CAGR?
Total return is often misleading over long periods. Compound Annual Growth Rate (CAGR) provides a smoother, annualised view of how an index performed. It answers the question: "What was the steady annual interest rate needed to grow the start value to the end value?"
- Eliminates Volatility Bias: Shows the geometric mean of growth.
- Better Benchmarking: Compare an index directly to a savings account rate.
- Realistic Planning: Helps forecast future wealth based on historical norms.
Investor Note
Remember that past performance is never a guarantee of future results. The UK market has unique sector exposures (like Banking, Mining, and Staples) which may perform differently than other global markets like the US (Tech-heavy S&P 500).
