Definition:
The Securities and Exchange Commission (SEC) is the primary regulatory authority for the U.S. securities markets. Its mission is to protect investors, maintain fair and efficient markets, and facilitate capital formation. Founded in 1934 in response to the 1929 stock market crash, the SEC enforces securities laws and oversees market participants such as public companies, brokers, exchanges, and investment firms.
Core Functions of the SEC:
- Investor Protection: Ensures full and fair disclosure by public companies to prevent fraud and manipulation
- Market Integrity: Promotes transparent, efficient, and orderly functioning of financial markets
- Regulatory Oversight: Supervises broker-dealers, investment advisers, mutual funds, and exchanges
- Corporate Disclosure: Mandates timely and accurate reporting (e.g., quarterly earnings, material events)
- Enforcement: Investigates violations such as insider trading, accounting fraud, and Ponzi schemes
Key Divisions:
| Division | Responsibility |

| Corporation Finance | Oversees disclosure by public companies |
| Investment Management | Regulates mutual funds, ETFs, and investment advisers |
| Trading and Markets | Monitors broker-dealers, exchanges, and clearing agencies |
