Securities Regulation & Enforcement

Get Started


This guide is meant to help you find laws and information on securities law issues; the goal is to provide useful, but not exhaustive, resources. Research requires analysis and synthesis of information, and no one resource will likely provide sufficient information or data on any given topic.

While conducting your research, you may want to explore: 

For many of the relevant databases, you will need your Harvard Key or University ID and PIN.  For others, you may need to register with your Harvard email address to gain access.  If you have any trouble accessing a database, please contact the library.

Legal Database Practice Centers

The following legal research databases all contain Practice Centers or Practice Areas focusing on the regulation of securities. While each database provides links to relevant statutes, regulations, administrative guidance, and case law, they each offer a different array of secondary sources and practice tools. As a result, it is a good idea to consult as many as possible.

Primary Sources of Law

Statutes, Regulations, and Cases


Investing in stocks, bonds, and other securities is different from putting savings in a bank account, as investments can lose value. The laws, rules, and regulations that govern the U.S. securities industry are designed to provide investors with access to certain basic information about an investment before they invest in it and while they continue to own it. The primary U.S. federal regulators are the Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC); however, individual states also have securities divisions that govern securities sold within the state.  

Below are links to a number of publicly available sources of statutes, rules, and regulations concerning the regulation of securities. You can also use various legal research databases (e.g., Bloomberg Law, Lexis, and Westlaw) to access these law and other resources.

The SEC's website also contains a useful summary on researching federal securities laws (including explanations and links to publicly available resources).

US Statutes

The official codified version of federal securities law appears in Title 15 of the U.S. Code, specifically in sections 77 through 80. (Note: Most practitioners refer to the section numbers of the Acts instead of citations to the Code.)

The SEC's website contains a lot of useful information regarding the laws listed above.

Congressional Committees

State Statutes (a/k/a "Blue Sky Laws")

NOTE: The origin of the term "blue sky laws" is a bit uncertain. See footnote 59 of this article by Jonathan R. Macey and Geoffery P. Miller if you are curious about some of the competing theories.

Federal Regulatory Agencies

There are two (2) main federal agencies regulating and overseeing securities markets and transactions in the US:

US Regulations

SEC rules are found in Chapter II of Title 17 (Commodities and Securities Exchanges). Different parts of the chapter correspond to specific topics, and each part is divided into sections that correspond to rule numbers.

For example:

  • 1933 Act Rule 144 is 17 C.F.R. § 230.144
  • 1934 Act Rule 10b–5 is 17 C.F.R. § 240.10b–5

The SEC's website contains a lot of useful information regarding various rules and regulations.

Regulatory Guidance

In addition to issuing regulations, the SEC releases a variety of interpretive guidance designed to clarify its interpretation of the securities laws and regulations. Although interpretive releases do not have the force of law, they can be very persuasive. You can find interpretive guidance on the SEC's website, under the "Regulation" tab (see "Other Notices and Orders" and "Staff Interpretations").

You can also find interpretive guidance in: 

  • Westlaw (in the "Securities Enforcement & Litigation" Practice Area, under "Administrative Decisions & Guidance"),
  • Lexis Advance (in the "Securities Law" Practice Area, under "Administrative Materials"), and/or
  • Bloomberg Law (in the "Securities" Practice Center, under "Agency & SRO Materials").

NOTE: "SRO" stands for "Self-Regulating Organization."

See "Finding Regulatory Information, Corporate Disclosures, Law Firm Memos, and More" on the "Useful Tools" page.


Legal research platforms (e.g., Westlaw, Lexis Advance, and Bloomberg Law) often allow you to focus your case law searches on specific areas of law. For example, Westlaw allows you to limit cases by the Topic of Securities, Lexis Advance allows you to select the Practice Area of Securities Law, and Bloomberg Law allows you to search Securities Court Opinions. By doing this, you can focus your case law research on the cases most likely to be relevant to your research question.

Required Disclosures (EDGAR)

The SEC's EDGAR (Electronic Data Gathering, Analysis, and Retrieval) System

Companies (and other entities) required to register with the SEC are required to make disclosure filings with the SEC using its Electronic Data Gathering, Analysis, and Retrieval – a/k/a "EDGAR" – system. These filings contain a wealth of information, both about the companies (or individuals) making the filings and as "real life" examples of drafting in a broad range of situations. For additional information on using EDGAR as a research tool, please see:

Subscription legal research platforms provide more robust searching capabilities, especially for searching across companies:

  • Lexis Securities Mosaic (can also access via Lexis Advance - browse by Practice Center => Securities; then launch Securities Mosaic under "Real Time SEC EDGAR, SEDAR, and UK Filings")
  • Westlaw (see Practice Area => Securities Enforcement & Litigation => EDGAR Filings & Disclosures)
  • Bloomberg Law
    • Click on the "Browse" link (to the left of the search bar), then select "Corporate & Transactional."
      • To search for EDGAR filings, click on "EDGAR Search"
      • To search follow SEC disclosure issues, click on "EDGAR Comment Threads"
      • To search for No-Action Letters, click on "SEC No-Action Letters"
    • Construct your search using the template provided
    • For guidance in constructing searches, click on "Example Searches" instead of selecting a specific type of search

SEC's Enforcement Division

The Division of Enforcement is the "police force" of the SEC. It's job is to gather evidence of possible violations of securities laws and regulations and recommend prosecution when necessary. Civil actions can be brought against regulatory violators in U.S. District Court or as an administrative proceeding with an administrative law judge (ALJ). With respect to possible criminal violations, the Division of Enforcement can recommend that state or federal criminal prosecutors bring charges. ALJ decisions may be appealed to the SEC Commissioners and ultimately to a U.S. Court of Appeals.
