In finance, a "share" refers to a unit of ownership in a company, corporation or fund. Shares can be bought and sold on stock exchanges, other trading platforms, or privately if it is a private company.

When a company is formed, it is divided into shares, and each share represents a portion of the ownership of the company. Shareholders own a part of the company proportional to the number of shares they hold.

Owning shares in a company can provide investors with various benefits, including the potential for capital appreciation, dividend income, and voting rights at shareholder meetings. Shares are an important part of the financial system and play a key role in allowing companies to raise capital and investors to participate in the growth and success of businesses.
