What Is Securities Law? A Complete Guide to Securities Regulation in the United States

Introduction

Securities law is the body of law that regulates the creation, offering, sale, trading, and disclosure of investments such as stocks, bonds, and other financial instruments.

In simple terms, securities law is designed to make investment markets more transparent and to protect investors from fraud, deception, manipulation, and significant undisclosed risks.

It governs questions such as:

  • What is a security?
  • When may a company sell stock to investors?
  • What information must an issuer disclose?
  • When must a securities offering be registered?
  • What securities offerings are exempt from registration?
  • What conduct constitutes securities fraud?
  • What is insider trading?
  • Who regulates securities markets?
  • What information must public companies periodically disclose?
  • When can investors sue?
  • What powers does the Securities and Exchange Commission have?

In the United States, securities regulation is primarily federal, although state securities laws—commonly called blue sky laws—also play an important role.

Cornell Law School’s Legal Information Institute provides a useful overview of securities law and its principal federal statutes, explaining that the central purpose of securities regulation is to address investors’ informational needs and promote informed investment decisions.

The subject can appear complicated because it involves corporations, finance, administrative law, contracts, fraud, corporate governance, and litigation simultaneously. But its underlying structure is relatively coherent.

At its core, securities law asks a fundamental question:

What information should investors have, and what conduct should the law prohibit, before and during the process of investing other people’s money?


1. What Is a Security?

The first question in securities law is often the most important:

Is the financial arrangement actually a security?

A security may take many forms, including:

  • common stock;
  • preferred stock;
  • bonds;
  • debentures;
  • certain notes;
  • investment contracts;
  • interests in certain investment arrangements;
  • options and other securities-related instruments; and
  • certain other financial interests defined by federal law.

Stock is the easiest example.

When an investor purchases shares of a corporation, the investor acquires an ownership interest in the company.

A bond is different.

A bond generally represents a debt obligation: the investor lends money to an issuer in exchange for a promise of repayment, usually with interest.

But securities law is not limited to traditional stocks and bonds.

Some arrangements that do not look like conventional securities may nevertheless fall within the statutory definition.

This is why determining whether something is a security is often a major legal issue.


2. Substance Over Labels

A company cannot necessarily avoid securities regulation simply by giving an investment a different name.

Courts generally examine the substance and economic reality of an arrangement rather than relying exclusively on the label chosen by the parties.

This becomes particularly important with investment contracts.

The U.S. Supreme Court developed the famous Howey test in SEC v. W.J. Howey Co. to determine whether an arrangement constitutes an investment contract.

Cornell’s explanation of the Howey test identifies the familiar elements of an investment of money in a common enterprise with an expectation of profits derived primarily from the efforts of others.

The principle is important because financial innovation constantly creates arrangements that do not fit neatly into traditional categories.

A legal system based entirely on labels would quickly become obsolete.


3. Why Does Securities Law Exist?

The central justification for securities regulation is information.

Investors usually know much less about a company than the company’s management.

Imagine that a corporation wants to raise $100 million by selling shares.

Management may know:

  • the company’s financial condition;
  • its debts;
  • its business plans;
  • pending litigation;
  • major contracts;
  • regulatory problems;
  • risks facing the company;
  • executive compensation;
  • expected acquisitions; and
  • significant weaknesses in its business.

A prospective investor may know very little.

This creates an information imbalance.

Securities law attempts to address that imbalance by requiring disclosure of important information and prohibiting deceptive conduct.

The objective is not to guarantee that investors make profitable investments.

That distinction is essential.

Securities law generally does not promise investors that their investments will succeed.

Instead, it seeks to make the decision-making environment more honest and informed.


4. The Historical Origins of Federal Securities Law

Modern federal securities regulation emerged largely from the economic crisis surrounding the stock market crash of 1929 and the Great Depression.

Before the federal securities framework developed, investors could encounter:

  • exaggerated promotional claims;
  • inadequate financial information;
  • fraudulent securities offerings;
  • manipulation;
  • speculative schemes; and
  • conflicts of interest.

The stock market crash demonstrated the consequences of an environment in which investors could make enormous financial decisions without reliable information.

Congress responded with major federal legislation.

Two statutes became the foundation of modern federal securities regulation:

  1. the Securities Act of 1933; and
  2. the Securities Exchange Act of 1934.

The distinction between them is fundamental.


5. The Securities Act of 1933

The Securities Act of 1933 primarily regulates the initial offering and sale of securities.

In simplified terms, it focuses on the process through which securities enter the market.

Suppose a corporation decides to sell shares to investors for the first time in a public offering.

The Securities Act may require registration with the Securities and Exchange Commission unless an exemption applies.

The purpose is primarily disclosure.

The issuer must provide investors with material information about:

  • the company;
  • its financial condition;
  • the securities being offered;
  • management;
  • the risks involved; and
  • other information required by federal law.

Cornell’s overview of the Securities Act of 1933 explains that the statute uses registration and disclosure requirements to help investors make informed decisions.


6. Registration Is the General Rule—but Not the Absolute Rule

A common misunderstanding is:

“Every securities offering must be registered with the SEC.”

That is not correct.

The general framework requires registration of securities offerings unless an exemption applies.

Congress and the SEC have created numerous exemptions.

These can include certain:

  • private offerings;
  • limited offerings;
  • offerings to particular categories of investors;
  • transactions that do not involve a public offering;
  • securities exempted by statute; and
  • transactions qualifying under SEC regulations.

This distinction is extremely important in business law.

A private company raising money from investors may not necessarily conduct a registered public offering.

Instead, the company may rely on an exemption if it satisfies the applicable requirements.


7. Private Placements

A private placement is a securities offering that does not involve a traditional public offering.

Private companies frequently raise capital through private securities offerings.

For example:

A technology startup raises $5 million from a group of venture capital funds and qualified investors.

The company may seek to structure the transaction under an exemption from federal registration requirements.

One important framework is Regulation D, which provides exemptions for certain private offerings.

Cornell’s overview of Regulation D explains that it governs certain private placements under federal securities law.

Private offerings remain subject to legal requirements.

An exemption from registration does not necessarily mean:

“Anything is permitted.”

Anti-fraud rules and other requirements may still apply.


8. Rule 506 and Private Capital Raising

Rule 506 is particularly important in private capital markets.

It allows qualifying issuers to conduct certain private offerings without registering the securities under the ordinary public-offering process.

Rule 506 is divided into different regulatory pathways, including Rule 506(b) and Rule 506(c).

The details matter.

For example, rules concerning:

  • accredited investors;
  • non-accredited investors;
  • disclosure;
  • solicitation;
  • verification;
  • resale restrictions; and
  • filing requirements

can differ depending on the exemption used.

The broader lesson is that securities regulation frequently turns on statutory and regulatory exemptions rather than on a simple public-versus-private distinction.


9. The Securities Exchange Act of 1934

The Securities Exchange Act of 1934 addresses a different stage of the securities system.

The 1933 Act focuses heavily on the initial offering of securities.

The 1934 Act primarily addresses securities trading and the ongoing regulation of the securities markets.

It regulates areas such as:

  • securities exchanges;
  • broker-dealers;
  • public company reporting;
  • insider trading;
  • market manipulation;
  • proxy solicitation;
  • tender offers; and
  • securities fraud.

Cornell’s overview of the Securities Exchange Act of 1934 describes the statute as primarily governing secondary-market transactions and establishing the SEC.

This creates a useful distinction:

Securities Act of 1933Securities Exchange Act of 1934
Initial offeringsSecondary markets
IssuersPublic companies and market participants
RegistrationOngoing reporting
Prospectus/disclosurePeriodic disclosure
Primary marketTrading markets
Securities offeringsExchanges and broker-dealers

The distinction is not absolute, but it provides an essential conceptual foundation.


10. The Securities and Exchange Commission

The Securities and Exchange Commission (SEC) is the principal federal agency responsible for administering and enforcing federal securities laws.

The SEC has broad responsibilities.

It:

  • adopts securities regulations;
  • reviews certain registration statements and filings;
  • regulates securities exchanges;
  • regulates various market participants;
  • investigates potential violations;
  • brings enforcement actions;
  • seeks civil penalties;
  • seeks injunctions and other remedies;
  • oversees self-regulatory organizations; and
  • provides regulatory guidance.

The SEC therefore occupies a central position in the American securities system.

But the SEC is not itself the source of all securities law.

Its authority comes from statutes enacted by Congress.

The relationship can be understood as:

Congress → statutes → SEC rulemaking → market regulation and enforcement


11. Primary Markets

A primary market is where securities are sold by an issuer to investors.

Suppose a corporation issues new shares and sells them to investors.

The corporation receives the capital.

That is a primary-market transaction.

The money flows from investors to the issuer.

For example:

Investors purchase newly issued shares for $50 million.

The corporation receives $50 million to fund its business.

Primary markets are therefore closely connected to corporate finance.

Companies use securities offerings to raise capital for:

  • expansion;
  • research;
  • acquisitions;
  • debt repayment;
  • infrastructure;
  • hiring;
  • technology; and
  • general corporate purposes.

12. Secondary Markets

A secondary market is where investors trade securities that have already been issued.

Suppose:

Maria buys 100 shares of Company X.

Later, Maria sells those shares to David.

Company X generally does not receive the proceeds from that resale.

The transaction occurs between investors.

That is a secondary-market transaction.

Examples of secondary-market venues include securities exchanges and over-the-counter markets.

Secondary markets are essential because they provide liquidity.

An investor is more willing to purchase a security if there is a reasonable possibility of selling it later.


13. Disclosure

Disclosure is one of the central concepts in securities law.

The law requires issuers and other market participants to disclose certain information in circumstances defined by federal securities laws and regulations.

The underlying principle is straightforward:

Investors should have access to material information necessary to make informed investment decisions.

Disclosure can concern:

  • financial statements;
  • material business risks;
  • management;
  • executive compensation;
  • significant litigation;
  • major transactions;
  • financial condition;
  • business operations;
  • ownership;
  • governance; and
  • other material developments.

But securities law does not require companies to disclose literally everything.

The legal concept of materiality is therefore extremely important.


14. Materiality

A fact is generally considered material when there is a substantial likelihood that a reasonable investor would consider it important in making an investment decision, or that disclosure of the fact would significantly alter the total mix of available information.

Materiality is therefore not synonymous with:

“Anything that might possibly interest an investor.”

Instead, it concerns information significant enough to matter to the investment decision.

Consider two examples.

Example One

A company is negotiating a major acquisition that could transform its business.

That may be material.

Example Two

The company changes the brand of its office coffee.

That is unlikely to be material.

The concept of materiality therefore acts as a boundary between meaningful securities information and ordinary corporate detail.


15. Securities Fraud

Securities law prohibits various forms of fraud and deception.

A securities fraud claim may involve:

  • false statements;
  • misleading statements;
  • material omissions;
  • deceptive schemes;
  • manipulation; or
  • other prohibited conduct.

One of the most important anti-fraud provisions is Section 10(b) of the Securities Exchange Act, together with SEC Rule 10b-5.

Cornell’s explanation of Rule 10b-5 describes its prohibition on deceptive schemes and material misstatements or omissions in connection with the purchase or sale of securities.

Securities fraud is therefore not limited to someone literally inventing a false number.

Misleading half-truths and material omissions can also create serious legal consequences.


16. Insider Trading

Insider trading concerns securities transactions involving material nonpublic information under circumstances prohibited by securities law.

Imagine that a corporate executive knows that the company is about to announce a massive undisclosed loss.

Before the announcement, the executive sells shares.

The executive may have obtained an unfair informational advantage.

That is precisely the type of problem securities law seeks to address.

The legal analysis of insider trading can become highly technical.

It can involve:

  • material nonpublic information;
  • insiders;
  • fiduciary duties;
  • tipping;
  • tippees;
  • misappropriation;
  • trading;
  • scienter; and
  • statutory and judicial doctrines.

The fundamental principle, however, is straightforward:

Securities markets cannot function fairly if participants secretly exploit material information in ways prohibited by law.


17. Market Manipulation

Securities law also addresses manipulation.

Market manipulation occurs when someone intentionally interferes with market forces to create a misleading appearance of supply, demand, price, or trading activity.

Examples may include schemes involving:

  • artificial trading;
  • coordinated price manipulation;
  • deceptive transactions;
  • false market signals; or
  • other conduct designed to distort securities prices.

Manipulation is different from simply making a bad investment prediction.

A person is generally allowed to be wrong.

The problem is intentionally creating a false market reality.


18. Public Company Reporting

Public companies may have continuing reporting obligations under federal securities laws.

Depending on the issuer and circumstances, required filings can include:

  • annual reports;
  • quarterly reports;
  • current reports concerning significant events;
  • proxy materials;
  • beneficial ownership reports; and
  • other regulatory filings.

For example, the familiar:

  • Form 10-K generally provides an annual report;
  • Form 10-Q provides quarterly reporting; and
  • Form 8-K is used for certain significant current events.

These filings give investors continuing access to information after the initial offering.

Securities regulation therefore does not end when a company first sells its securities.


19. Securities Exchanges and Broker-Dealers

Securities markets depend on intermediaries.

Broker-dealers help facilitate transactions between buyers and sellers.

Securities exchanges provide organized trading venues.

These market participants are subject to extensive regulatory requirements.

The regulatory framework addresses issues such as:

  • registration;
  • recordkeeping;
  • financial responsibility;
  • trading practices;
  • customer protection;
  • supervision;
  • disclosure; and
  • market integrity.

The SEC also oversees self-regulatory organizations, including FINRA, which plays a major role in regulating broker-dealers.


20. State Securities Laws: Blue Sky Laws

Federal securities law does not eliminate state securities regulation.

States have their own securities statutes, commonly called blue sky laws.

These laws can regulate:

  • securities offerings;
  • broker-dealers;
  • investment professionals;
  • fraud;
  • registration;
  • exemptions; and
  • enforcement.

The relationship between federal and state securities law can be complicated.

Federal law may preempt certain state requirements in particular circumstances, while state law may continue to apply in others.

Therefore, a securities transaction can potentially involve both federal and state regulation.


21. Securities Law and Corporate Law

Securities law and corporate law overlap, but they are not the same thing.

Corporate law generally governs the internal structure and operation of the corporation.

It addresses questions such as:

  • Who owns the corporation?
  • What powers do directors have?
  • What rights do shareholders possess?
  • How are officers appointed?
  • How are corporate decisions made?

Securities law, by contrast, focuses heavily on the relationship between issuers, investors, and securities markets.

It addresses questions such as:

  • Can the company sell securities?
  • What must it disclose?
  • Is the offering registered?
  • Does an exemption apply?
  • Can insiders trade?
  • Has the market been manipulated?
  • Has an investor been defrauded?

The two bodies of law therefore overlap but serve different purposes.


22. Securities Law and Contract Law

Securities transactions also involve contracts.

For example, an investor may sign:

  • a subscription agreement;
  • a purchase agreement;
  • a shareholder agreement;
  • a private-placement agreement; or
  • a bond agreement.

Contract law may govern the agreement between the parties.

But securities law may impose additional obligations that cannot simply be contracted away.

A company cannot necessarily say:

“The investor agreed that the company could lie.”

Contractual language does not automatically eliminate mandatory securities-law requirements.

This illustrates a broader principle:

Securities law operates partly as a regulatory framework around private transactions, rather than merely as a set of contractual rules.


23. Securities Law and Corporate Finance

Securities law is also closely connected to corporate finance.

A company has several broad methods of obtaining capital.

It can:

  • borrow money;
  • issue shares;
  • issue bonds;
  • obtain venture capital;
  • conduct a private placement;
  • conduct a public offering; or
  • use other financing structures.

Each financing method creates different legal consequences.

For example:

Equity financing may give investors ownership rights.

Debt financing generally creates an obligation to repay.

Securities law becomes particularly important when these financial claims are offered or traded as securities.


24. Initial Public Offerings

An initial public offering (IPO) occurs when a private company offers its securities to the public for the first time.

An IPO involves substantial legal and financial preparation.

The company may need to address:

  • registration;
  • disclosure;
  • financial statements;
  • corporate governance;
  • underwriting;
  • risk factors;
  • executive compensation;
  • litigation;
  • capitalization;
  • securities exchange requirements; and
  • continuing reporting obligations.

The IPO illustrates how securities law connects corporate law, finance, accounting, investment banking, and regulatory law.


25. Exempt Securities and Exempt Transactions

Another important distinction is between:

  • exempt securities, and
  • exempt transactions.

An exempt security may fall outside certain registration requirements because of the type of instrument involved.

An exempt transaction may involve a security that would ordinarily be regulated but is sold through a transaction qualifying for an exemption.

This distinction can become technically important when analyzing a securities offering.

The correct question is therefore not merely:

“Is this exempt?”

It is:

“What requirement is being avoided, and what specific statutory or regulatory exemption provides the basis?”


26. Securities Law Remedies

Violations of securities laws can produce several types of consequences.

Depending on the statute and circumstances, remedies may include:

  • rescission;
  • damages;
  • civil penalties;
  • disgorgement;
  • injunctions;
  • administrative sanctions;
  • bars from serving as officers or directors;
  • trading restrictions; and
  • criminal penalties in appropriate cases.

The SEC can bring enforcement actions.

Government prosecutors may pursue criminal violations.

Private investors may also have private rights of action in certain circumstances.

Not every securities-law violation creates a private lawsuit.

That distinction is extremely important.


27. Federal Enforcement and Private Litigation

Securities law therefore has two important enforcement dimensions.

Public enforcement

Government agencies such as the SEC can investigate and bring enforcement actions.

Private enforcement

Certain federal securities statutes allow private plaintiffs to sue when statutory requirements are satisfied.

Private securities litigation may arise from:

  • securities fraud;
  • misleading registration statements;
  • unlawful sales;
  • disclosure violations; or
  • other statutory violations.

Private securities litigation is often complex because federal statutes impose detailed requirements concerning:

  • standing;
  • causation;
  • materiality;
  • scienter;
  • reliance;
  • damages;
  • pleading;
  • limitations periods; and
  • class actions.

28. The Importance of Scienter

Some securities claims require proof of scienter, meaning a particular level of wrongful intent or knowledge.

This is important because securities law does not treat every mistake as fraud.

Consider two situations.

Situation One

A company accidentally makes a minor accounting error.

Situation Two

Corporate executives knowingly falsify financial statements to inflate the stock price.

These situations are morally and legally different.

The second may involve scienter and securities fraud.

The exact mental-state requirement depends on the claim being asserted.


29. Securities Regulation and Risk

Securities law does not eliminate investment risk.

This distinction should always be kept in mind.

A perfectly lawful investment can lose money.

A company may:

  • fail;
  • lose customers;
  • face competition;
  • experience declining profits;
  • suffer an economic shock; or
  • become insolvent.

None of these events automatically establishes a securities-law violation.

Securities regulation attempts to prevent fraudulent or legally prohibited manipulation of investment decisions, not ordinary economic uncertainty.

This is why disclosure is so important.

The investor must ultimately decide whether the disclosed risk is worth taking.


30. A Practical Securities-Law Analysis

When confronted with a securities-law problem, a useful sequence is:

Step 1: Identify the instrument

Ask:

What exactly is being offered or traded?

Is it:

  • stock?
  • bond?
  • note?
  • investment contract?
  • partnership interest?
  • digital asset?
  • derivative?
  • another financial instrument?

Step 2: Determine whether it is a security

Apply the applicable statutory definition and, where relevant, judicial tests such as Howey.

Step 3: Identify the transaction

Is this:

  • an initial offering?
  • a private placement?
  • a secondary-market sale?
  • a resale?
  • a public offering?

Step 4: Identify the applicable statute

Consider:

  • Securities Act of 1933;
  • Securities Exchange Act of 1934;
  • other federal securities statutes;
  • SEC regulations; and
  • state securities laws.

Step 5: Determine whether registration is required

If so, ask whether an exemption applies.

Step 6: Examine disclosure

Was required information provided?

Were material facts omitted?

Were statements misleading?

Step 7: Examine conduct

Was there:

  • fraud?
  • manipulation?
  • insider trading?
  • an unlawful offering?
  • an unauthorized transaction?

Step 8: Identify the regulator

Determine whether the SEC, FINRA, a state regulator, or another authority has jurisdiction.

Step 9: Determine available remedies

Finally, ask whether the consequences include:

  • SEC enforcement;
  • administrative sanctions;
  • civil liability;
  • private litigation;
  • rescission;
  • damages; or
  • criminal prosecution.

31. Common Misunderstandings

“Securities law exists to guarantee investors profits.”

False.

It is primarily concerned with disclosure, market integrity, and preventing prohibited conduct.

“The SEC approves every investment.”

False.

SEC registration is not the same as government approval of an investment’s quality.

Registration generally concerns compliance with disclosure and regulatory requirements.

“A security must be a stock.”

False.

Stocks are securities, but securities law covers many other instruments and arrangements.

“Private companies do not have to follow securities laws.”

False.

Private companies can still issue securities and may be subject to federal and state securities laws.

“An exempt offering is completely unregulated.”

False.

An exemption may eliminate a particular registration requirement while leaving other legal requirements intact.

“Every securities-law violation allows an investor to sue.”

False.

Private rights of action depend on the specific statute, claim, and applicable legal requirements.

“If an investment loses money, there must have been securities fraud.”

False.

Investment losses can result from ordinary business and market risk.


32. The Deeper Principle: Information and Trust

Securities markets ultimately depend on trust.

An investor buys a share because the investor believes the share represents a genuine economic interest.

A lender buys a bond because the lender believes the issuer will honor its obligations.

A market functions because participants believe that prices are not systematically produced by fraud and manipulation.

Securities law therefore serves an institutional purpose.

It attempts to create a legal environment in which:

capital can move toward businesses, investors can make informed decisions, and markets can function without systematic deception.

This does not require the government to decide which companies deserve investment.

Instead, securities law generally attempts to establish rules under which investors can make their own decisions using reliable information.

That is why the disclosure principle is so central.


33. Securities Law as the Law of Information in Capital Markets

There is a useful way to conceptualize securities law:

Corporate law governs much of the internal organization of the company.

Contract law governs many voluntary agreements between parties.

Commercial law facilitates transactions.

Securities law governs the legal conditions under which investment capital enters and moves through financial markets.

Its central concern is therefore not simply ownership.

It is information, trust, fairness, and market integrity.

That is what makes securities law one of the most important branches of modern business law.

Frequently Asked Questions

What is securities law?

Securities law is the body of federal and state law governing securities offerings, trading, disclosure, market participants, and prohibited conduct such as securities fraud and manipulation.

What is a security?

A security is a financial instrument or investment arrangement falling within applicable statutory definitions. Common examples include stocks and bonds, while certain other arrangements may qualify depending on their legal and economic characteristics.

What are the main federal securities laws?

The two foundational federal statutes are the Securities Act of 1933 and the Securities Exchange Act of 1934.

What does the Securities Act of 1933 regulate?

It primarily regulates the initial offering and sale of securities and establishes registration and disclosure requirements, subject to statutory and regulatory exemptions.

What does the Securities Exchange Act of 1934 regulate?

It primarily regulates secondary-market trading, public-company reporting, securities exchanges, broker-dealers, insider trading, market manipulation, and securities fraud.

What is the SEC?

The Securities and Exchange Commission is the principal federal agency responsible for administering and enforcing federal securities laws.

What are blue sky laws?

Blue sky laws are state securities laws regulating securities offerings, sales, market participants, and fraud within individual states.

What is securities fraud?

Securities fraud generally involves prohibited deceptive conduct connected to securities transactions, such as material misstatements, material omissions, fraudulent schemes, or manipulation.

What is insider trading?

Insider trading generally concerns prohibited securities trading involving material nonpublic information or other conduct that violates applicable securities laws.

Does the SEC guarantee that an investment is safe?

No. Securities regulation does not guarantee investment success. A registered or lawfully offered security can still lose substantial value.

Do private companies have to comply with securities law?

Yes. Private companies can issue securities and may be subject to federal and state securities laws, although particular offerings may qualify for exemptions from registration.

Why is disclosure so important?

Because investors generally have less information about an issuer than the issuer’s management. Securities regulation seeks to reduce this information imbalance and allow investors to make informed decisions.


Conclusion

Securities law is fundamentally about the relationship between investment, information, and trust.

When a company raises money from investors, the investors are making decisions based largely on information about the company and the investment being offered. If that information is materially false or incomplete, the market cannot function fairly.

The American securities-law system therefore developed a framework built around several connected principles:

disclosure, registration, exemptions, market integrity, anti-fraud rules, investor protection, and regulatory oversight.

The Securities Act of 1933 addresses much of the process by which securities enter the market. The Securities Exchange Act of 1934 governs much of what happens afterward, including trading, reporting, exchanges, broker-dealers, and market conduct. The SEC administers and enforces the federal framework, while state blue sky laws provide an additional layer of regulation.

The ultimate objective is not to tell investors which investments will succeed.

It is to create a market in which investors have a meaningful opportunity to decide for themselves.

That distinction captures the philosophy of securities regulation:

The law cannot eliminate investment risk, but it can attempt to prevent deception from becoming part of the price of admission to the market.
