Stockbrokers have two roles to play on AIM in that they can act for companies which are quoted on AIM or they can act for investors who wish to deal in AIM securities.
All companies on AIM must also have a broker and this will be a member firm of the Stock Exchange. If there is no registered market maker then the role of the broker will include using its best endeavours to find matching business. However, generally speaking, the role of the broker will be more wide ranging than this and will include the publication of research on the company, dealing in the company’s shares on behalf of institutional and private investors, raising finance from investors and providing corporate finance advice.
