A simple definition of a security is any proof of owner ship or debit that has been
assigned a value and may be sold. (Today, evidence of ownership is likely to be a
computer file, while once it was a written piece of paper.) For the holder, a security
represents an investment as an owner, creditor or rights to ownership and which the
person hopes to gain profit. Examples are stocks, bonds and options.
The securities and Exchange Act of 1934
provides the more complicated definitions.
