What Is the Alternative Investment Market (AIM)?

The Alternative Investment Market (AIM) is a sub-market of the London Stock Exchange (LSE) that is designed to help smaller companies access capital from the public market. AIM allows these companies to raise capital by listing on a public exchange with much greater regulatory flexibility than the main LSE stock market.

Key Takeaways

  • The Alternative Investment Market (AIM) is a specialized unit of the London Stock Exchange (LSE) catering to smaller, more risky companies.
  • The companies listed on AIM tend to be smaller and more highly speculative, in part due to AIM's relaxed regulations and listing requirements.
  • Since launching in 1995, AIM has helped more than 3,988 companies raise over £130 billion.

Understanding the Alternative Investment Market (AIM)

AIM opened its doors in 1995 to 10 companies with a combined market capitalization of about £82 million. Since then, it has helped more than 3,988 companies raise over £130 billion as of 2022 and is home to approximately 852 companies with a combined market cap of almost £135 billion as of January 2022.

Companies seeking an initial public offering (IPO) and listing on AIM are usually small companies that have exhausted their access to private capital but are not at the level required to undergo an IPO and list on a large exchange.

Although AIM is still referred to as the Alternative Investment Market, or London’s Alternative Investment Market in the financial press, the LSE has made a practice of referring to it by its acronym only.

AIM and the Nomads

The process for a company listing on AIM follows much the same path as a traditional IPO, just with less stringent requirements. There is still a pre-IPO marketing blitz, with historical financial information to stir up interest, and a post-IPO lock up, for example.

One key difference is the role nominee advisors, commonly known as nomads, play in the process. These nomads are seen as the regulatory system for AIM and are tasked with advising the companies pre-IPO and after.

One issue that is frequently raised about this relationship is the fact that nomads are responsible for ensuring regulatory compliance, but they also profit in the form of fees from the companies they list and continue to oversee as part of the listing agreement.

The FTSE Group maintains three real-time indexes for tracking AIM: the FTSE AIM UK 50 Index, the FTSE AIM 100 Index, and the FTSE AIM All-Share Index.

AIM’s Reputation as a Less-Regulated Market

AIM is seen as a more speculative investment forum due to its relaxed regulations compared to larger exchanges. The regulation for companies listed on AIM is often referred to as being light-touch regulation, as it is essentially a self-regulated market where nomads are tasked with adhering to the broad guidelines.

There have been cases of nomads failing to do their duties, as it were, and AIM is not a stranger to outright fraud—to be fair, no major exchange is either. As a result, AIM tends to attract sophisticated and institutional investors who have the risk appetite and resources to perform independent due diligence.

AIM has been criticized for being a financial wild west where companies with questionable ethics go for money. This criticism has held up in some cases, particularly with extraction companies operating in impoverished regions of the world.

However, AIM has also shown the value of having a gap market where risk-hungry investors can help accelerate cash-starved companies along their growth path, benefiting the company, its investors, and the economy as a whole.

What Is the Difference Between LSE and AIM?

The Alternative Investment Market (AIM) is a sub-segment of the London Stock Exchange (LSE). AIM was created with the goal of helping smaller or riskier companies have access to capital via the public markets. These are companies that would not qualify to be listed on the LSE.

Is the Alternative Investment Market (AIM) a Recognized Stock Exchange?

The Alternative Investment Market (AIM) is regulated by the London Stock Exchange (LSE), which is a recognized stock exchange. Companies listed on AIM adhere to AIM Rules for Companies, not the Listing Rules of the LSE.

Can Americans Buy on the London Stock Exchange?

Yes, Americans can buy assets on the London Stock Exchange. They can do so via American depository receipts, opening up foreign accounts with brokers and trading through them, or trading contracts for difference (CFD).

The Bottom Line

Meeting the listing requirements of large stock exchanges can be difficult for smaller companies, yet, these companies still have a need to access exchanges in order to raise capital. The Alternative Investment Market (AIM) of the London Stock Exchange (LSE) caters to small companies, providing them with the opportunity to list their shares and raise capital for their business needs.
