Regulatory Summaries

A quick-reference summary of the main federal laws and FINRA rule themes that reappear across Series 6.

On this page

Series 6 does not require deep securities-law analysis, but it does expect the candidate to recognize which regulatory source controls a problem. This appendix is a routing tool for that purpose.

Rule or lawWhy Series 6 cares
Securities Act of 1933registration and prospectus framework for new issues
Securities Exchange Act of 1934market regulation and broker-dealer oversight
Investment Company Act of 1940rules affecting mutual funds, UITs, and similar products
FINRA communications ruleshow firms supervise retail communications and correspondence
suitability and best-interest standardsrecommendation logic and customer-fit discipline

Key Takeaways

  • The exam often rewards the candidate who picks the right rule family before solving the question.
  • Regulatory summaries are shortcuts, not substitutes for full chapter study.
  • The strongest answer usually connects the rule source to customer protection or supervision.
