A security is an investment or financial claim, such as a stock or bond, whose precise legal status depends on its rights, offering, and governing law.
A security is an investment or financial claim, such as a share, bond, fund interest, option, or investment contract, that gives its holder economic or contractual rights. The precise legal meaning depends on the instrument, transaction, and jurisdiction. A product does not become a security merely because it can gain value, and calling it a token, membership, note, commodity, or contract does not necessarily keep it outside securities law.
This page uses security in the financial and legal sense, not to mean cybersecurity, collateral, or physical safety.
| Category | Typical holder right | Examples | Main risk question |
|---|---|---|---|
| Equity security | Residual ownership, possible voting rights, and dividends if declared | Common shares, some preferred shares | How much value remains after senior claims? |
| Debt security | Contractual interest and principal payments | Government bonds, corporate bonds, notes | Can the issuer pay on time, and where does the claim rank? |
| Fund or pooled interest | Proportionate interest in a managed pool or investment company | Mutual fund shares, ETF shares, limited partnership interests | What assets, fees, leverage, liquidity, and manager risks sit underneath? |
| Derivative security | Exercise, payment, or delivery rights linked to another asset or measure | Listed options, warrants, some convertible or structured products | What drives the payoff, and can the position expire or lose all value? |
| Investment contract | Rights arising from an investment arrangement rather than a conventional certificate | Fact-specific ventures or schemes | Do the transaction’s economic realities satisfy the governing legal test? |
These categories can overlap. A convertible bond combines a debt claim with an equity conversion right, while a preferred share can contain debt-like payment or redemption features.
An Issuer creates or becomes obligated under a security. Investors provide capital or acquire the security from another holder. The governing documents define the resulting rights.

The diagram is illustrative. A secondary-market buyer pays the selling holder rather than the issuer, and an intermediary may be the registered holder while the investor remains the beneficial owner.
| Term | Scope | Important boundary |
|---|---|---|
| Security | Investment or financial claim within a particular legal or market framework | Not every asset or contract is a security |
| Financial Instrument | Broader contractual category used in finance and accounting | Can include receivables, payables, deposits, derivatives, and equity instruments that are not discussed as securities in every context |
| Financial asset | Cash, an equity holding, or a contractual right to receive cash or exchange financial instruments on favorable terms under an applicable accounting framework | Accounting classification is not the same as securities-law status |
| Collateral | Property or rights supporting an obligation | A security can serve as collateral, but collateral is not what the word security means here |
| Security interest | Legal interest in collateral that secures payment or performance | Distinct from an investment security |
| Investment product | Broad commercial term for securities and other regulated or contractual products | Deposits, insurance, commodities, or collectibles may follow different rules |
The answer is jurisdiction-specific. Some statutes list conventional instruments such as stocks, bonds, debentures, notes, transferable shares, and investment contracts. Courts and regulators may also examine the economic substance of an arrangement rather than rely only on its label.
In U.S. federal law, section 2(a)(1) of the Securities Act contains a broad list of instruments and interests. For an investment contract, the Supreme Court’s Howey framework examines an investment of money in a common enterprise with a reasonable expectation of profits derived from the essential managerial efforts of others. Applying that framework is fact-sensitive. Other named instruments, including some notes, can require different analysis.

This is a review sequence, not a legal test for every country. A conclusion that an asset itself is not a security also does not automatically resolve whether an offer, contract, wrapper, intermediary activity, or derivative involving it is regulated.
First determine whether the instrument or transaction is a security. Then determine how its offer and sale comply with applicable law.
| Question | What it addresses |
|---|---|
| Is it a security? | Instrument or transaction classification |
| Is the offering registered? | Whether a regulatory registration statement covers the offer and sale |
| Does an exemption apply? | Whether the security or transaction can be offered without full registration, subject to conditions |
| Is the security restricted? | Whether resale limitations apply after issuance |
| Is ownership registered? | Whose name appears on issuer or transfer-agent records |
An exempt offering can involve a security. A security sold in a registered offering can later be held in street name. A Registered Security may refer to ownership form rather than regulatory offering status.
A security’s legal status does not tell an investor how easily it can be sold.
A private security may be transferable only with consent. An unlisted security may trade actively over the counter. A listed security can become illiquid. A government savings bond can be a security while lacking ordinary secondary-market transferability. Use Marketable vs. Non-Marketable Securities for the full comparison.
A company issues $50 million of five-year bonds. Each bond has a $1,000 face amount, pays stated interest, and promises principal at maturity. The bonds are issued under governing documents and sold to investors.
The bond is economically a debt claim and is conventionally treated as a security. That conclusion does not answer the remaining questions:
Calling the bond an “investment security” adds little without this contract and market information. Its value depends on promised cash flows, issuer credit, interest rates, optionality, liquidity, and recovery expectations.
Suppose a promoter sells digital memberships that provide access to a future platform and also markets the opportunity around profits expected from the promoter’s continuing development and management. The word “membership” does not settle the classification.
A reviewer would examine the rights sold, purchaser motivation, use of proceeds, representations or promises, managerial efforts, transfer arrangements, and applicable legal tests. The result could differ if the product is sold solely for immediate consumptive use without an investment arrangement. This example illustrates why substance and transaction facts matter; it does not classify any actual product.
Security valuation depends on the claim rather than the label:
Face value, issue price, carrying amount, fair value, and market price answer different questions. None is automatically the amount an investor will recover.
