What Is a Security?

A security is an investment that can be bought or sold on financial exchanges or other platforms. The investment’s monetary value is determined when traded. Investors can earn money by buying a security at a low price and selling it at a high price.

Categories of Securities 

The following are common categories of securities:

Equity Securities

Equity securities, or stocks, represent partial ownership in a company:

• Equity securities might pay dividends, which are distributions of the company’s profits.

• Each security’s value can fluctuate based on the company’s performance and market conditions.

• Investors can earn returns through capital gains if the equity security’s value increases.

• If an issuer files for bankruptcy, shareholders are paid after all debts have been settled.

Debt Securities

Debt securities involve lending money to a company, government, or other entity in exchange for regular interest payments and the return of the principal amount by the maturity date:

• Examples of debt securities include bonds and Treasury notes.

• Debt securities do not grant ownership or voting rights.

• Investors are repaid regardless of the issuer’s performance.

• The securities might be secured, meaning backed by collateral, or unsecured.

• If an issuer goes bankrupt, secured debt has priority.

Hybrid Securities

Hybrid securities combine elements of debt and equity securities, including the following:

• Equity warrants: Options giving shareholders the right to buy the stock at a set price on a specified date.

• Convertible bonds: Bonds that can be converted into shares of stock under predefined conditions.

• Preferred stock: Stocks that allow shareholders to receive interest, dividends, and other capital returns before other stockholders.

Derivatives

Derivatives are financial contracts whose value is derived from the price of an underlying asset, which could be a commodity, such as gas, gold, or coffee, or a currency, bond, or stock:

• Options and futures contracts are examples of derivatives that let investors speculate on price movements without directly owning the underlying asset.

• Companies and institutional investors often use derivatives to hedge against price fluctuations in underlying assets.

• Derivatives can be traded over the counter or on exchanges.

How Securities Are Traded

Securities are traded in public and private markets:

• The first time a company issues equity securities is through an initial public offering (IPO).

• Afterward, any newly issued shares are considered secondary offerings.

• Secondary offerings are sold in the primary market, where securities are first created and issued.

Public Market

Publicly traded securities are listed on stock exchanges, where issuers offer a liquid, regulated market for buying and selling shares to attract investors. These securities can also be traded over-the-counter (OTC), where transactions take place between buyers and sellers.

After securities have been issued, they can be resold in the secondary market, also known as the aftermarket. Investors buy and sell shares for cash or capital gains.

Private Market

Securities can be sold through private placements, meaning they are offered to a select, qualified group of investors rather than the general public. Some companies choose a combination of both public and private placements when raising capital.

How Securities Are Regulated

In the U.S., the Securities and Exchange Commission (SEC) regulates the issuance, trading, and sale of securities. The goal is to enhance transparency, protect investors, and prevent fraud in the financial markets. Public offerings and sales must be registered with the SEC and comply with disclosure requirements.

Self-regulatory organizations (SROs), such as the Financial Industry Regulatory Authority (FINRA), help oversee brokerage firms and trading practices. There are also global regulatory organizations, such as the International Organization of Securities Commissions (IOSCO), which sets international standards for consistency across markets.
