FTSE AIM 100 Index

The FTSE AIM 100 Index is a market index that includes the largest companies listed on the Alternative Investment Market (AIM), a sub-market of the London Stock Exchange. It tracks the performance of firms that meet specific criteria for market capitalisation and liquidity.

Index Methodology and Construction

The FTSE AIM 100 Index is compiled using a free-float market capitalisation method. Only shares readily available for public trading are used to calculate each company’s weighting in the index. This approach allows the index to reflect the performance of actively traded companies, ensuring proportional representation within the AIM market framework.

Sector Representation

Companies within the FTSE AIM 100 Index span a broad set of industries. These include technology firms offering software and IT services, healthcare companies developing pharmaceutical or medical solutions, and energy groups working in both conventional and renewable fields. Other sectors such as media, telecommunications, and industrial manufacturing also feature in the index, reflecting the diversity of AIM-listed firms.

Criteria for Inclusion

Inclusion in the FTSE AIM 100 Index is based on ranking by market capitalisation and compliance with minimum liquidity requirements. Only companies that maintain a consistent trading record and meet specific thresholds are eligible. The selection process is entirely rules-based and applies uniform standards to all constituents, with no discretionary judgment involved.

Rebalancing and Review Process

The FTSE AIM 100 Index is reviewed quarterly. During these scheduled reviews, companies may be added or removed depending on their current market capitalisation and trading activity. The purpose of rebalancing is to ensure that the index continues to represent the most significant and actively traded AIM-listed firms based on the latest available data.

Role in Market Segmentation

As an index that tracks top-tier companies on the AIM market, the FTSE AIM 100 Index plays a role in segmenting the UK equities landscape. It focuses specifically on growth-stage firms that have reached a relatively higher market capitalisation within AIM, distinguishing them from smaller or less liquid companies on the same exchange.

Corporate Profiles and Market Presence

Many companies within the FTSE AIM 100 Index operate with a global footprint while maintaining listings in the UK. These firms are often involved in emerging technologies, scientific research, and data-driven services. The companies are publicly traded and must comply with AIM’s regulatory and reporting standards, contributing to transparency in the market.

Market Position and Strategic Focus

The FTSE AIM 100 Index provides structured representation of larger entities within the AIM environment. It showcases firms with established market presence and measurable trading activity. The composition reflects both sector performance and the evolving structure of the AIM segment of the London Stock Exchange.
