What Is the SEC?
The Securities and Exchange Commission is an independent federal agency established in 1934 to restore trust in markets after the 1929 crash and the abuses that preceded it. Its mission rests on the principle of full and fair disclosure: companies can sell securities to the public as long as they tell investors the truth about their operations, financial condition, risks, and management.
Five commissioners appointed by the president lead the agency, with one serving as chair and a maximum of three drawn from any single political party. Major divisions include Corporation Finance, which reviews company filings, Trading and Markets, which oversees exchanges and broker-dealers, Enforcement, which investigates violations, and Investment Management, which regulates funds and advisers.
What the SEC Regulates
Public companies must register securities offerings and file ongoing disclosures, including annual 10-Ks, quarterly 10-Qs, current-event 8-Ks, and proxy statements, all freely available through the EDGAR database. The agency reviews IPO registration statements before shares can be sold and can force companies to amend disclosures it finds inadequate.
The enforcement side pursues insider trading, accounting fraud, market manipulation, and disclosure violations, with the power to levy civil fines and bar individuals from the securities industry, while criminal matters are referred to the Department of Justice. Landmark laws have expanded the agency's reach over time, from the Sarbanes-Oxley Act's audit reforms in 2002 to Dodd-Frank's post-crisis mandates in 2010.
Why the SEC Matters in Finance Careers
Analysts live inside SEC filings. Comparable company analysis pulls share counts and financials from 10-Ks and 10-Qs, while precedent transaction work relies on merger proxies and 8-Ks. IPO teams spend months responding to SEC comment letters on the S-1 registration statement before a deal can price.
Compliance with SEC rules also shapes daily life on Wall Street, from restricted lists and information barriers at banks to the marketing rules governing how funds advertise performance. Knowing what the SEC requires, and where to find filings on EDGAR, is a basic professional skill that interviewers assume candidates already have.
