Index Structure and Composition

The FTSE All Share is made up of constituents from the FTSE 100, FTSE 250, and FTSE SmallCap indices. Each group reflects different market capitalizations, providing a balanced view of large, mid, and smaller-sized companies. This diversified structure helps to reflect the collective movement of listed UK equities across a wide economic spectrum.

Energy is represented by companies involved in oil, gas, and alternative energy sources. Consumer goods and consumer services cover retail, food, and leisure businesses. Other sectors include utilities, telecommunications, industrials, real estate, and healthcare.

Weighting Methodology

Companies in the FTSE All Share are weighted by market capitalization. This methodology assigns higher weights to companies with larger market value. As a result, movements in these companies can influence the overall direction of the index more significantly than smaller constituents. The weighting also determines sectoral influence, based on the aggregate market value of companies within each segment.

It was designed to provide comprehensive coverage of the UK equity landscape, reflecting long-term trends and sector shifts. The composition evolves regularly, with companies added or removed based on eligibility and size criteria.

Changes in global economic conditions, domestic developments, and corporate results influence sector standings.
