A hallmark of the IAA is the required registration of virtually all investment advisers. Much verbiage, however, has gone into exactly what constitutes an investment adviser and corollary—investment advice. The act defines an investment adviser as "any person who, for compensation, engages in the business of advising others, either directly or through publications or writings, as to the value of securities or as to the advisability of investing in, purchasing, or selling securities, or who for compensation and as part of a regular business, issues or promulgates analyses or reports concerning securities." The SEC further refined its definition of an adviser in its Release 1092, which stated that the "giving of advice need not constitute the principal business activity or any particular portion of the business activities in order for a person to be an investment adviser." Release 1092 went on to state that the "giving of advice need only be done on such a basis that it constitutes a business activity occurring with some regularity. The frequency of the activity is a factor, but is not determinative."
