Business Finance-Full disclosure law

Federal regulation developed as a direct result of the debacle in the securities markets during the early 1930s. The first major pieces of legislation were the Securities Act of 1933 and the Securities Exchange Act of 1934. These are concerned with issuing and trading securities. The 1933 act covers new issues of securities, and the 1934 act is devoted to trading in existing securities. To administer these acts, the Securities and Exchange Commission (commonly called the SEC) was established.
