SEC

What Is the SEC?

Congress created the SEC in 1934, five years after the 1929 crash wiped out investors who had bought shares on rumours, borrowed money and almost no reliable information. The Securities Act of 1933 had just required companies to register new offerings. The Securities Exchange Act of 1934 extended the rules to trading on exchanges and set up a commission to enforce both laws.

The design is simple to describe. The SEC does not decide which investments are good or bad, and it does not approve a company’s business plan. It requires the company to tell the truth, in a standard format, and then lets investors decide. A stock can be risky and still fully legal, while a safe-sounding investment sold with false claims is a violation.

Five commissioners run the agency, appointed by the president for staggered five-year terms, and no more than three can come from the same party. Beneath them sit divisions that review company filings, oversee exchanges and brokers, supervise funds and bring enforcement cases. Its jurisdiction covers securities in the broad sense: stocks, bonds, fund shares and any other instrument the law treats as an investment contract.

How Does the SEC Work?

Most of the SEC’s work happens through filings. A company going public files a registration statement with audited accounts and a list of risk factors. After listing, it files an annual 10-K, quarterly 10-Q reports and an 8-K within four business days of major events such as a merger or a chief executive leaving. All of it goes onto EDGAR, a free public database, which is why a trader anywhere can read the same numbers a Wall Street analyst sees.

Funds follow a parallel regime. The Investment Company Act of 1940 governs every US mutual fund and ETF, setting rules on custody, leverage, pricing and conflicts of interest. Advisers who manage client money register under a separate 1940 law and must act in their clients’ best interest.

Enforcement is the second half. The SEC investigates insider trading, accounting fraud, market manipulation such as a pump and dump, and unregistered offerings. It files civil cases in federal court or before its own administrative judges, and the Department of Justice can bring criminal charges on the same facts.

How the SEC Decides What Is a Security

Whether a product falls under SEC rules often comes down to one Supreme Court case. In the 1946 case SEC v. Howey, a Florida company sold strips of orange grove to buyers who had no plan to farm them and simply collected a share of the profits. The Court ruled the arrangement was an investment contract, and the four-part Howey test it created still applies to new products, crypto tokens included.

The test asks whether there is an investment of money, in a common enterprise, with an expectation of profit, derived from the efforts of others. Picture a startup that raises $20 million by selling tokens before its network exists, telling buyers the team will build the product and that the token should rise in value as usage grows. Buyers paid money, their fortunes rise and fall together, they expect profit, and that profit depends on the team’s work, so all four prongs are met.

Under that reading, the sale is an unregistered securities offering. The issuer could face an order to return the $20 million, a penalty and a requirement to register the tokens, which is roughly what happened to many projects after the 2017 initial coin offering boom.

Courts do not always read the test the same way. In SEC v. Ripple Labs, a federal judge ruled in July 2023 that XRP sold directly to institutions was a security, while XRP sold anonymously on exchanges to retail buyers was not, because those buyers could not know they were funding Ripple. The case ended in August 2024 with a $125 million civil penalty, far below the roughly $2 billion the SEC had sought.

Why Is the SEC Important for Traders?

SEC decisions move prices because they decide who can access a market. When the SEC approved the first US spot bitcoin ETFs on 10 January 2024, pension funds, advisers and brokerage customers gained a regulated way to hold bitcoin exposure through an ordinary stock account. Enforcement cuts the other way: a lawsuit naming a token as a security can lead US exchanges to delist it within days.

Disclosure rules also create the calendar traders work around. Earnings arrive in scheduled 10-Q and 10-K filings, large shareholders must report stakes above 5%, and company insiders must disclose their own trades. Those filings turn private information into public data at set moments, which is why prices often jump on filing days.

The limitation is that the SEC mostly acts after the damage. Harry Markopolos sent the SEC detailed warnings about Bernie Madoff from 2000 onward, yet the fraud ran until Madoff confessed in December 2008, with paper losses of about $65 billion. Regulation by enforcement also leaves gaps in fast-moving markets such as crypto, where rules have shifted with changes in agency leadership and projects often learned their status only from a lawsuit.

Key Takeaways

• The SEC is the US federal regulator for securities markets, created in 1934 to enforce disclosure rules for companies, exchanges, brokers and funds.
• Its model relies on disclosure rather than approval: an investment can be risky and legal, but it cannot be sold with false or missing information.
• The Howey test decides whether a product is an investment contract, and it applies to crypto tokens as much as to orange groves.
• SEC approvals and lawsuits change who can access a market, which is why ETF decisions and token cases move prices.
• Enforcement usually comes after harm is done, so SEC oversight does not replace your own research into what you buy.
