Insider dealing definition

Insider dealing, or insider trading, is an illegal activity that involves making an investment based on information that is not available to the general public.

Insider dealing is not necessarily limited to company managers. Investment brokers, or anyone else with access to insider information about a qualifying investment can be guilty of it.

In the UK, insider dealing has been a criminal offence since 1980 and is currently set out in Part V of the Criminal Justice Act 1993. If prosecuted, insider dealing can result in a fine and/or up to seven years' imprisonment.
