Securities

Definition

A fungible, negotiable financial instrument that holds some type of monetary value.

Deep Dive

Securities are fungible, negotiable financial instruments that represent some type of monetary value. They typically fall into three main categories: equity securities (representing ownership in a company, like stocks), debt securities (representing a loan made by an investor to a borrower, like bonds), and derivative securities (whose value is derived from an underlying asset or index, like options and futures). These instruments are fundamental to financial markets, enabling governments and corporations to raise capital while providing investors with opportunities to grow wealth through various risk-return profiles.
