Investor

Definition
An investor is any party that makes an investment.

Overview
The term has taken on a specific meaning in finance to describe the particular types of people and companies that regularly purchase equity or debt securities for financial gain in exchange for funding an expanding company. Less frequently, the term is applied to parties who purchase real estate, currency, commodity derivatives, personal property or other assets.

The term implies that a party purchases and holds assets in hopes of achieving capital gain or cash flow, not as a profession or for short-term income.
