An investor is a person who allocates financial capital with the expectation of a future return (profit) or to gain an advantage (interest). Through this allocated capital the investor usually purchases some species of property. Types of investments include equity, debt, securities, real estate, infrastructure, currency, commodity, token, derivatives such as put and call options, futures, forwards, etc. This definition makes no distinction between the investors in the primary and secondary markets. That is, someone who provides a business with capital and someone who buys a stock are both investors. An investor who owns stock is a shareholder.
