Main / Glossary / Security


In the realm of finance, security refers to a tradable financial instrument that holds value and is considered an investment. Securities are commonly bought and sold on various financial markets, providing individuals and institutions the opportunity to diversify their portfolios and potentially earn returns. This dictionary entry aims to provide a comprehensive understanding of different types of securities and their characteristics within the context of finance, billing, accounting, corporate finance, business finance bookkeeping, and invoicing.

Characteristics and Types of Securities:

1. Stocks:

Stocks, also known as shares or equity, represent ownership in a company. By purchasing stocks, investors become partial owners, or shareholders, of the company and have a claim on its assets, earnings, and voting rights. Stocks are often traded on public stock exchanges and can generate returns through capital appreciation and dividend payments.

2. Bonds:

Bonds are debt instruments issued by corporations, governments, or other entities to raise capital. When purchasing a bond, investors effectively lend money to the issuing entity in return for periodic interest payments and the full repayment of the principal amount at maturity. Bonds are considered fixed-income securities and are generally less volatile than stocks, making them an attractive option for risk-averse investors.

3. Mutual Funds:

Mutual funds are investment vehicles that pool money from multiple investors to invest in a diversified portfolio of securities, such as stocks, bonds, or a combination of both. Professional fund managers make investment decisions on behalf of the investors, aiming to achieve specific investment objectives. Mutual funds offer investors the opportunity to access a wide range of securities without directly owning them, providing diversification and professional management.

4. Exchange-Traded Funds (ETFs):

Similar to mutual funds, ETFs also offer investors the opportunity to access a diversified portfolio of securities. However, unlike mutual funds, ETFs can be bought and sold on stock exchanges throughout the trading day, just like individual stocks. ETFs are designed to track specific indexes, sectors, or asset classes and provide investors with the ability to gain exposure to a specific market segment while maintaining the benefits of diversification.

5. Options:

Options are derivative securities that provide the holder the right, but not the obligation, to buy or sell an underlying asset at a predetermined price within a specified period. This underlying asset can be a stock, index, bond, or even a physical commodity. Options are commonly used for hedging, speculation, or income generation purposes, offering investors flexibility and the potential for significant returns.

6. Futures:

Futures contracts are agreements to buy or sell an asset, such as commodities or financial instruments, at a predetermined price at a future date. Futures are standardized contracts traded on regulated exchanges, allowing market participants to speculate on the future price movements of the underlying asset or engage in hedging strategies. Futures contracts are often used by producers, consumers, and investors to mitigate the risks associated with price volatility.


Securities play a vital role in the world of finance, providing individuals and institutions with opportunities to invest, diversify their portfolios, and manage risk. Understanding the various types of securities is crucial for making informed investment decisions and achieving financial goals. Whether buying stocks to gain ownership in a company, investing in bonds to earn fixed income, or trading options and futures for risk management or profit potential, the world of securities offers a wide array of possibilities for both individual and institutional investors. By staying informed and consulting with financial professionals, investors can navigate the complex landscape of securities to build wealth and achieve financial success.
