ALTERNATIVE INVESTMENT MARKET (AIM)
Alternative Investment Market ( AIM)
Aim is designed as a separate market for the shares of smaller growing companies that are not yet ready for a full listing on the London Stock Exchange. It allows them access to investment capital without the cost and regulatory burdens of a full listing on the main market. The Aim is usually used as a stepping stone to the main market. Financial Services Glossary
The shares of companies on the AIM can be risky because the companies don't have long track records and if you want to sell your investment there are not always buyers for your shares. However, there is a potential for big rewards. Financial Services Glossary
