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.
