Definitions

In plain terms

Stocks and bonds are common securities. A security has its own rights and identity; its issuer, exchange listing, and ticker are related records rather than the security itself.

Technical

The glossary uses security as an instrument-level entity that may have stable identifiers, one or more listings, a currency denomination, and corporate-action history.

Scope

Legal definitions vary by jurisdiction; this educational definition supports data modeling and does not provide a legal classification.

Examples

  • One class of common stock is a security that may be listed on more than one trading venue.

Common misconceptions

  • A company is not a security, and one company can issue many different securities.
