What is Stock?
A stock represents a share of ownership in a company, giving you a claim on its assets and earnings. Stocks, also known as equities, are a type of security traded on public exchanges where investors buy and sell them to seek profits through price appreciation or dividends.
Understanding stocks is fundamental to building a diverse portfolio and assessing potential rate of return on your investments.
Key Characteristics
Stocks come with distinct features that influence your investment decisions:
- Ownership and Voting Rights: Common stockholders typically have voting rights, allowing you to influence corporate decisions, unlike preferred stockholders who usually do not vote.
- Dividend Payments: Some stocks pay regular dividends, especially dividend stocks, while others reinvest earnings for growth.
- Types of Stocks: Common stock offers capital growth potential with higher risk; preferred stock provides more stable income but less upside.
- Market Capitalization: Stocks are categorized by size, such as large-cap, mid-cap, and small-cap, each with unique risk and growth profiles. See our guide on best large-cap stocks for examples.
- Risk Level: Stocks vary from stable blue-chip companies to volatile pennystocks, which carry higher risks and speculative potential.
How It Works
When you buy stock, you purchase a fractional ownership stake in a company, entitling you to a share of profits through dividends or capital gains as the stock price rises. Stocks trade on exchanges where prices fluctuate based on supply, demand, and company performance.
Investing in stocks requires evaluating factors such as company fundamentals, market conditions, and your personal investment goals. Incorporating factor investing strategies can help identify stocks with desirable characteristics like value, momentum, or quality.
Examples and Use Cases
Stocks span various industries and investment styles, allowing you to tailor your portfolio:
- Technology: Ownership in companies like Apple offers exposure to innovation and growth potential.
- Airlines: Stocks such as Delta provide insight into the industrial and transportation sectors.
- Mid-Cap Opportunities: Mid-sized firms balancing growth and stability can be found in our best mid-cap stocks guide.

Important Considerations
Stock investing involves risks such as market volatility and potential loss of principal, so it's essential to assess your risk tolerance and diversify your holdings. Evaluating stocks across sectors and sizes can help mitigate risks associated with economic cycles.
Before investing, understand the specific characteristics of each stock type and consider how dividends, voting rights, and company fundamentals align with your financial objectives.
Final Words
Stocks offer a way to share in a company’s growth and income but come with varying levels of risk depending on type and market factors. Assess your risk tolerance and investment goals before selecting common or preferred shares to build a portfolio that aligns with your financial plan.
Frequently Asked Questions
Stock represents shares of ownership in a company, giving investors a claim on its assets and earnings. People invest in stocks to potentially earn money through price appreciation, dividends, or both, although investing in stocks carries risks like market volatility and possible loss of principal.
Common stock gives shareholders voting rights and potential for higher returns through capital gains, but dividends are not guaranteed and holders are last in line during liquidation. Preferred stock usually does not include voting rights but offers fixed dividends with priority over common stock, providing more stability but less growth potential.
Stocks are classified by market capitalization, which is the total value of a company's outstanding shares. Categories include large-cap (over $10 billion), mid-cap ($2–$10 billion), small-cap (under $2 billion), mega-cap (over $200 billion), and micro-cap (under $300 million), each with different risk and growth characteristics.
Growth stocks are shares in companies expected to grow earnings rapidly, often reinvesting profits and rarely paying dividends, which makes them higher risk but with potentially higher rewards. Value stocks, on the other hand, are considered undervalued compared to their fundamentals and may offer appreciation potential as the market recognizes their true worth.
Income stocks pay regular dividends and usually come from stable sectors like utilities or real estate. They appeal to investors seeking steady income rather than rapid growth, offering lower volatility and consistent payouts.
Market sectors group stocks by industry based on classification standards like the Global Industry Classification Standard. This helps investors understand the economic area a company operates in, such as technology, healthcare, or financials, which can affect stock performance and investment strategies.
Investors in stocks face risks like market volatility, where prices can fluctuate widely, and the potential loss of their invested principal. Additionally, factors such as company performance, economic conditions, and sector trends can impact stock value.
