A FTSE Index is a stock market index created by FTSE Russell, one of the world’s leading index providers. These indices track the performance of specific markets, regions, or investment segments.

Examples include the FTSE 100, which tracks major UK companies, and the FTSE All-World Index, which covers global markets. Investors often use FTSE indices as benchmarks for investment performance.

Many ETFs and index funds are designed to replicate FTSE indices, making them widely used in passive investing strategies.
