What is the term for investment actions that have specific legal requirements and restrictions?

The term "regulated transactions" refers to investment actions that are subject to specific legal requirements and restrictions. This encompasses a wide range of activities in the financial markets that must comply with regulations set forth by securities authorities and organizations, such as the SEC.

These regulations can include rules about transparency, reporting, conduct, and the types of investments that can be made, which serve to protect investors and ensure fair market practices. Regulated transactions may involve securities offerings, trading practices, and compliance with anti-fraud provisions, among others, all of which are designed to create a stable and trustworthy investment environment.

In contrast, the other terms do not encapsulate the concept of legal frameworks governing transactions. Margin trading involves borrowing funds to purchase securities and carries its own set of risks and regulations, but it does not broadly cover all investment actions. Speculation refers to high-risk investments aimed at substantial returns without guaranteed safety, but it also does not imply adherence to legal requirements. Fiduciary duties involve the obligations owed by one party to another, particularly in a trustee relationship, but this is not a direct reference to the regulated nature of investment transactions. Hence, "regulated transactions" accurately describes investment actions within the legal framework of financial regulations.
