Investment Company Act of 1940

Definitions, fund types, registration, and operating rules under the Investment Company Act.

The Investment Company Act of 1940 is one of the most important statutes for Series 6 because it governs the product family at the center of the license. Mutual funds, closed-end funds, UITs, and related pooled vehicles all make more sense once you understand that this law is about how investment companies are structured, registered, and operated for investor protection.

Series 6 questions often hide this statute inside product details. Instead of naming the Act directly, they test fund classification, board and custody protections, valuation discipline, or limits on affiliated activity. The better instinct is to think, “This is a rule about how the fund itself must exist and operate,” which points you back to the 1940 Act.
