Who is an insider in the stock market?

The word insider has a specific meaning in market rules. This guide explains who counts as an insider, why the definition is wide and what duties come with being one.

Quick answer

An insider is any person who has access to a company's unpublished price-sensitive information, or who is connected to the company in a way that gives such access. This includes employees, directors and others linked to the company. Insiders face strict rules on when and how they can trade the company's shares.

Key takeaways

  • An insider has access to secret price-sensitive information.
  • It includes employees, directors and connected people.
  • The definition is deliberately wide.
  • Insiders face strict trading restrictions.
  • Being an insider brings legal duties.

What is an insider?

An insider is a person who has access to a company's unpublished price-sensitive information, or who is connected to the company in a way that could give such access. The focus is on access to secret, market-moving information.

So an insider is not only a senior executive. Anyone who, through their role or connection, can reach secret information about the company may be treated as an insider.

Who can be an insider?

Insiders can include employees at many levels, directors, promoters and professionals who work with the company, such as auditors or advisers. Even close connections of these people can sometimes be covered.

The definition is wide on purpose. Secret information can leak through many routes, so the rules cast a broad net to catch anyone who might misuse it.

Why is the definition so wide?

A narrow definition would be easy to dodge. If only top bosses were insiders, secret information could be passed to others who then trade freely. A wide definition closes this gap.

PersonCould be an insider?
Employee with accessYes
DirectorYes
Adviser to the companyYes

By covering a broad range of people, the rules make it harder to escape responsibility simply by using a go-between to trade.

What duties do insiders have?

Insiders must not trade while holding secret price-sensitive information. They may face a closed trading window before major news, and some must get pre-clearance before dealing in the company's shares.

They must also help keep secret information secure, following the company's code of conduct designed to prevent misuse.

What should investors know?

If you ever come into secret company information, for example through work, you may be treated as an insider and must not trade on it. This applies even to casual access.

Understanding who is an insider helps you avoid crossing into insider trading. Any investment decision should be your own after proper research using public information.
