A businessperson (also business person, businessman, business man, businesswoman, or business woman) is someone involved in business, in particular undertaking of activities, commercial or industrial, for the purpose of generating revenue from a combination of human, financial, and physical capital that further fuels economic development and growth. An entrepreneur is an example of a business person. Though the term usually refers to founder, owner, or majority shareholder of a business, sometimes the term can mean someone who is involved in the upper level management role of a corporation, company, organization, or agency. Sometimes it can also mean someone employed in a (usually) profit-oriented enterprise. The term businessperson/man/woman almost always refers to someone with a “white collar” occupation.
Publicly and privately held for-profit corporations confer corporate titles or business titles on company officials as a means of identifying their function and responsibility in the organization. In addition, many non-profit organizations, educational institutions, partnerships, and sole proprietorships also confer corporate titles.
An investor is a person who allocates capital with the expectation of a financial return. The types of investments include: gambling and speculation, equity, debt securities, real estate, currency, commodity, derivatives such as put and call options, etc. This definition makes no distinction between those in the primary and secondary markets. That is, someone who provides a business with capital and someone who buys a stock are both investors. Since those in the secondary market are considered investors, speculators are also investors. According to this definition there is no difference.
