Share vs. Stock: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on October 24, 2023
A share represents ownership in a specific company, while stock is a general term for ownership in any company.

Key Differences

A share can be best understood as a unit of ownership in a particular company. When an individual buys a share, they are buying a portion of that specific company, making them a shareholder. Stock, on the other hand, is a more general term that refers to ownership in any company or the collective shares of multiple companies.
When discussing investments, people often use the term "buying stock" to refer to the act of purchasing ownership in a company. However, what they're technically purchasing are shares of that company. If someone says they have stock in the tech sector, it means they have shares in one or more tech companies.
The value of a share is determined by several factors, including the company's performance, the economy, and market speculation. In contrast, the term "stock" does not have a specific value by itself, but it refers to the collective value of shares in a company or sector.
Companies issue shares to raise capital, and these shares are then traded on stock exchanges. The word stock can be used to describe the overall market, such as when one refers to the "stock market," meaning the collective trading of many companies' shares.
It's essential to recognize that while all shares are stocks, not all stocks are shares. A share is specific to one company, whereas stock is a broad term that can encompass the ownership certificates of many companies.
