The FTSE AIM 100 Index is a market index representing the largest companies by market capitalisation listed on the Alternative Investment Market (AIM) of the London Stock Exchange. This index spans multiple sectors such as biotechnology, renewable energy, digital technology, mining, and industrial engineering. It serves as a benchmark for tracking the performance of prominent companies on AIM, which often includes emerging businesses with dynamic operational models.

Structure and Composition of the Index

The index is composed of one hundred companies from various industries. These firms are selected based on their market size and are periodically reviewed. Each company within the index is subject to eligibility requirements that include free float and liquidity standards. Changes to the index are typically made at set intervals to reflect shifts in company valuations and overall market activity.

Sector Representation within the Index

The FTSE AIM 100 Index features firms from a broad array of sectors. Healthcare and life sciences contribute significantly due to ongoing advancements in pharmaceuticals and medical devices. Energy companies involved in exploration and alternative fuel sources are also prominent. In addition, technology firms developing software solutions and digital infrastructure hold considerable presence. Materials and natural resources play a vital role as well, particularly those focused on mining and resource extraction.

Market Performance Metrics

The index provides an aggregated view of performance trends across its constituents. It is widely monitored for shifts in market valuation and sectoral performance. While companies in the index may experience varied price movements, the overall index reflects collective changes based on weighted market capitalisation.

Eligibility and Criteria for Inclusion

Companies included in the FTSE AIM 100 Index must meet specific criteria concerning liquidity and market size. Regular reviews ensure that only firms meeting the current standards remain in the index. These assessments help maintain an accurate representation of the top tier of AIM-listed companies. Adjustments are implemented following a transparent and structured process.

Rebalancing and Index Maintenance

Rebalancing of the FTSE AIM 100 Index is conducted periodically. This process is based on updated data concerning market size and share volume. It ensures the index accurately reflects the evolving dynamics of the AIM market. Firms that grow or decline in value may enter or exit the index accordingly. This ongoing review supports consistency in index composition and methodology.

Global and Domestic Reach of Companies

Many businesses listed in the FTSE AIM 100 Index operate internationally, delivering products and services beyond the UK. These companies may have operations across Europe, Asia, and the Americas, depending on their industry and scope. Their inclusion in the index showcases a blend of domestic and global business activity within the AIM market framework.

Market Capitalisation and Sector Weightings

While market capitalisation remains a key determinant of index inclusion, sectoral representation is equally significant. Some sectors may have a greater presence depending on market demand and innovation. The index adjusts to these changes, reflecting shifts in capital flow and industrial focus over time.
