Four federal laws do most of the work. Know which one governs the new issue, the trading market, the fund and the adviser.
Four Acts, one idea: disclosure
The Securities Act of 1933 is often called the truth in securities law. It has two aims: investors get financial and other significant facts about securities offered for public sale, and fraud in selling them is banned. Registration is the main tool. The facts let investors, not the government, judge the offering. The SEC requires the information to be accurate but does not guarantee it. A buyer who loses money has recovery rights if she can prove the disclosure was incomplete or inaccurate.
The Securities Exchange Act of 1934 created the SEC. It covers the trading markets and the people in them. It gives the SEC power to register, regulate and oversee brokerage firms, transfer agents, clearing agencies and self-regulatory organizations such as the exchanges and FINRA. It lets the SEC require periodic reports from companies whose securities trade publicly, and it governs the proxy materials used to ask shareholders for their votes.
Two 1940 Acts finish the set. The Investment Company Act regulates companies, such as mutual funds, that invest in securities and sell their own shares to the public. It aims to limit conflicts of interest and focuses on disclosure and on fund structure and operations, but it does not let the SEC direct a fund’s investments or judge their merits. The Investment Advisers Act regulates firms paid to advise others about securities; generally the larger advisers, and advisers to registered funds, register with the SEC.
Disclosure only works if people can read it. Registration statements and prospectuses become public shortly after filing, and filings by U.S. companies are on the SEC’s EDGAR database, free. When a question asks what the SEC promises, the answer is accurate disclosure backed by enforcement. It is not a profit, and it is not an approval of quality.

Try it: Cover the table. Name the Act that governs each of four events: a company selling new shares to the public; a listed company filing its yearly report; a mutual fund describing its investment policies; a firm charging a fee for stock advice. Then say in one sentence what none of the four Acts promises an investor.
The closest contrast
1933: the new issue.
1934: the market after it.
This decides most “which Act” questions. If securities are being offered for sale, think 1933. If they already trade, or the question is about a broker-dealer, an exchange, an SRO or ongoing reports, think 1934.
Worked example
Nerys Hollingworth buys shares in a company’s new public offering and later holds them in her brokerage account while the company files its annual report.
- Before the sale, the 1933 Act applies: the company registers the offering and gives buyers a prospectus with the significant facts.
- The SEC reviews the filing for disclosure compliance. It does not decide whether the shares are a good buy.
- Once the shares trade, the 1934 Act applies: her broker-dealer is registered with the SEC, and the company files periodic reports.
- She can read every filing free on EDGAR. If the registration statement or prospectus for the offering left out important facts, the 1933 Act gives her recovery rights if she can prove it.
