In the context of financial assets, an equity is a share in the ownership of a publicly quoted company. For most companies there are two types of equity: ordinary shares, which have voting rights, and preference shares, which do not. Owners of preference shares rank ahead of ordinary shareholders in a liquidation. Equities are also referred to as "stocks" or "shares".

There are a number of advantages to owning shares in a business in this way. The stock exchange will have rules on how listed companies prepare and publish their accounts, how they disseminate 'price-sensitive' information, on the numbers of shares that are available to the public, and other such issues. Although itself a private business, any recognised exchange will be an essential part of business regulation in the country in which it operates.
