The Securities and Exchange Commission (SEC) is responsible for enforcing securities laws created by Congress. The SEC makes sure that any individual or company trying to sell securities fully discloses information about the securities being sold. This gives investors an opportunity to evaluate the security and make an informed decision to invest in it or not.
The SEC was formed in 1934 by Congress as part of the Securities Exchange Act of 1934. The SEC also ensures securities markets function in an orderly manner. As well, it oversees corporate takeovers since any company looking to take over another must register with the SEC.
