The correct answer is D, A bank money market deposit account. Under the Securities Act of 1933 and related SEC regulations, most investment instruments are classified as securities and are subject to federal securities laws. However, certain banking products are specifically excluded.
A bank money market deposit account is a banking product, not a security. It is typically offered by banks, insured by the FDIC (within limits), and regulated by banking authorities rather than the SEC. Because of this, it is exempt from securities registration requirements.
In contrast, the other choices are all considered securities. A debenture (choice A) is an unsecured corporate bond and clearly falls under the definition of a security. A fund of funds (choice B) is an investment company that invests in other mutual funds and is regulated as a security. A unit investment trust (UIT) (choice C) is also an investment company product registered under the Investment Company Act of 1940.
The key takeaway for the SIE exam is that banking products (like deposit accounts and CDs) are generally not securities, while investment products issued by corporations or investment companies are securities. Thus, choice D is correct.
