The U.S. Securities and Exchange Commission is a federal agency that regulates the U.S. stock market. By helping the U.S. economy, the SEC contributes to the high standard of living we enjoy today. Thanks to the SEC, the government has drastically reduced the chance of our country experiencing another Great Depression.

Formation History

In 1934, Congress created the SEC to restore the public’s confidence in financial markets after the 1929 stock market crash. The first chairman was Joseph Kennedy, President John F. Kennedy's father.

The Securities Exchange Act of 1934 created the SEC itself. But it couldn't have succeeded with the Securities Act of 1933. It required public corporations to register their stock sales. That meant they had to identify who the major holders were. 

Before the Act, a small group would hold a majority share of stocks. They could manipulate the markets without anyone knowing. The 1935 Public Utility Holding Company Act eliminated holding companies more than twice removed from the utilities whose stocks they held. 

That meant holding companies could no longer obscure the intertwined ownership of public utility companies. The act allowed the SEC to break up large utility combinations into smaller, geographically based companies. It also created the local federal commissions to regulate utility rates. 

The SEC's Current Role

The SEC maintains confidence in the U.S. stock market. That's critical to the strong functioning of the U.S. economy. It does this by providing transparency into the financial workings of U.S. companies. It makes sure investors can get accurate and consistent information about corporate profitability.

This allows investors to have a basis for determining a fair stock price for the company. Without this transparency, the stock market would be vulnerable to sudden shifts as hidden information came out. This lack of transparency was the reason for Enron’s failure. That wasn't a failure on the part of the SEC, it happened because Enron lied in its information submissions to the SEC.

The Commission prosecutes offenders like Enron. It also punishes insider trading, deliberate manipulation of the markets, and selling stocks and bonds without proper registration.

Some have concerns that the SEC is becoming less effective during the Trump administration. From February through September 2017, the agency collected $127 million in corporate civil penalties in 15 cases. That's much lower than the $702 million collected from 43 cases during the same period in 2016.


The SEC has five commissioners, appointed by the U.S. president. They have the support of 3,100 staff located in 18 offices across the country. 

The SEC is made up of five different divisions: 

  1. The Division of Corporation Finance reviews corporate filing requirements. It makes sure companies submit documents that are complete and accurate. That allows investors to understand a company's health.
  2. The Division of Trading and Markets maintains the standards that regulate the stock markets. It oversees the securities exchanges and securities firms. It also maintains surveillance over the industry's self-regulatory organizations. These include the Financial Industry Regulatory Authority, the Municipal Securities Rulemaking Board and clearing agencies that facilitate trade settlement. 
  3. The SEC has a division that oversees the Securities Investor Protection Corporation (SIPC). This private, non-profit corporation insures customers' investment accounts in case a brokerage company goes bankrupt. The Division of Investment Management regulates investment management companies, including mutual funds and variable annuities. It reviews documents submitted under the Sarbanes-Oxley Act of 2002.
  4. The Division of Enforcement investigates and prosecutes violations of securities laws and regulations. It conducts its investigations privately. It can use a formal order of investigation to subpoena witnesses to testify and produce relevant documents. The division presents its findings to the SEC Commission, which allows it to file a case in federal court. Often the Commission settles the case out of court.
  5. The Division of Economic and Risk Analysis provides economic and risk analyses to the other divisions. It predicts how proposed SEC rules would affect the markets and the economy. It reviews the overall risk in the markets. It provides early identification of potentially fraudulent activities. 

Impact on the U.S. Economy

The SEC increases transparency, consistency, and trust in the U.S. stock market. That's a big reason why the New York Stock Exchange is the most sophisticated and popular exchange in the world. This transparency attracts much business to U.S. financial institutions, including banks, and legal firms

It also makes it easier for companies to orchestrate their initial public offerings of stock. Many companies take their stock to the public markets when they have grown large enough to need equity financing for their next phase of development. The ease of going public helps U.S. companies grow larger and faster than those of other countries with less developed markets.

The SEC Commissioner sits on the Financial Stability Oversight Council. The Dodd-Frank Wall Street Reform Act established the council after the 2008 financial crisis. It looks for weaknesses in the financial markets that could create another crisis.

How the SEC Affects You

The SEC affects you by making it safer for you to buy stocks, bonds, and mutual funds. It does not regulate hedge funds or derivatives. The SEC provides a great depth of information to help you invest. 

Dodd-Frank required the SEC to study the financial literacy of the average American investor. It found that most investors don't understand the basics of how the markets or the economy work. It suggested ways to improve investors' knowledge.

A very useful SEC resource is It serves as an advocate for investors, providing basic education on topics such as how the markets work, asset allocation, and a review of different retirement plans. It also has a section on how to select a broker. You can find out if your broker is registered. It also gives you five steps to avoid investor fraud.

The site provides financial planning tools and can tell you how much money you need to retire. You can find out how fees impact your investments, and you can even learn how to manage the finances of an incapacitated parent.
