In 1946, SEC v W.J. Howey Co. (328 U.S. 293) ruled the meaning of “security” as used in the provision of § 2(1) of the Securities Act of 1933 defining “security” as : “For purposes of the Securities Act, an investment contract (undefined by the Act) means a contract, transaction, or scheme whereby a person invests his money in a common enterprise and is led to expect profits solely from the efforts of the promoter or a third party, it being immaterial whether the shares in the enterprise are evidenced by formal certificates or by nominal interests in the physical assets employed in the enterprise.”
There are three components:
1. expectation of profits
2. a common enterprise
3. depends “solely” for its success on the efforts of others.
