Investing: How It Works & Where to Start

Investing is one way to put money to work for long-term goals. Learn the basics of stocks, bonds, ETFs, index funds, retirement accounts, diversification, risk and compound growth with this beginner-friendly investing guide.

What Is Investing?

Investing means putting money into an asset with the expectation that it may produce a return over time. Depending on the investment, that return can come from an increase in value, interest, dividends or other income.

Common investments include stocks, bonds, mutual funds and exchange-traded funds (ETFs). Investor.gov also identifies additional investment categories such as Treasury securities, annuities and certain alternative investments.

Important: Investing is different from keeping money in a savings account. Investments can lose value, sometimes substantially. Your goals, time horizon and ability to tolerate losses should be considered before investing.

How Does Investing Work?

The basic idea is simple: you purchase an investment, hold it, and hope it generates a return over time. The actual result can be positive or negative.

For example, if you buy shares of a company and the share price increases, your investment may be worth more than you originally paid. A company may also distribute dividends. A bond may pay interest according to its terms.

Investment returns are not guaranteed. Investor.gov explains that all investments involve risk and that investors should understand both the potential return and the risks associated with an investment.

Common Types of Investments

Different investments have different characteristics, risks, potential returns and costs. Understanding the basic categories can make it easier to research investments that fit your goals.

Stocks vs. Bonds vs. Funds

These terms describe different ways to invest. A fund can contain many underlying investments, while an individual stock or bond represents a more specific investment.

Investment Basic idea What to consider
Stocks Ownership interest in a company. Price volatility, company performance and diversification.
Bonds Debt investment in which an issuer borrows money. Interest-rate risk, credit risk and maturity.
Mutual funds A pooled portfolio holding multiple investments. Fees, holdings, strategy and diversification.
ETFs A fund whose shares trade on an exchange. Fees, holdings, strategy, liquidity and trading costs.

No investment category is automatically appropriate for every investor. Consider the investment's purpose, risk, fees and diversification before investing.

Saving vs. Investing

Saving and investing serve different purposes. Savings are often used for short-term needs and emergencies where accessibility and stability are important. Investing is generally used for longer time horizons where you can accept fluctuations in value.

Saving Investing
Common purpose Near-term expenses and emergency reserves Longer-term financial goals
Value stability Generally designed for stability Can fluctuate
Access Usually highly accessible Depends on the investment and account
Potential return Usually lower potential return Potential for greater long-term growth, with investment risk

Before investing money you may need soon, consider whether you have enough cash available for emergencies and near-term expenses. PaycheckMint's emergency fund guide can help you plan that part of your finances.

Investment Risk and Return

Risk is the possibility that an investment will lose value or produce a different return than expected. Different investments carry different types and levels of risk.

Your investment choices should take into account your time horizon and risk tolerance. Someone investing for a goal many years away may have a different ability to handle market fluctuations than someone who expects to need the money soon.

Why higher potential returns can involve more risk

There is no guaranteed investment that provides a high return without risk. When evaluating an investment, look at what could cause you to lose money as well as what could produce a gain.

Investor.gov recommends understanding an investment's risks, fees and liquidity before investing.

What Is Diversification?

Diversification means spreading your money among different investments rather than relying on one company, security, sector or asset class.

The goal is to reduce the impact that one investment or part of the market can have on your overall portfolio. However, diversification does not guarantee a profit or prevent losses.

Investor.gov notes that asset allocation can involve dividing investments among asset classes such as stocks, bonds and cash, while diversification can spread holdings within those classes.

Simple example: Instead of putting all your investment money into one company's stock, a diversified portfolio might contain a broader mix of investments. The exact mix depends on the investor's goals, time horizon and risk tolerance.

Compound Growth and Long-Term Investing

Compound growth occurs when your investment earns returns and those returns remain invested, allowing future returns to build on a larger balance.

Time can be an important part of long-term investing because contributions and investment returns may accumulate over many years. However, actual investment returns vary, and historical performance does not guarantee future results.

Investing for Retirement

Retirement investing often happens through tax-advantaged accounts such as workplace 401(k) plans and individual retirement arrangements (IRAs).

A traditional 401(k) generally allows eligible employees to make elective contributions through payroll, while plans may also provide employer contributions. Some plans offer designated Roth contributions.

IRAs include traditional and Roth IRAs. The IRS explains that traditional IRA contributions may be deductible if eligibility requirements are met, while Roth IRA contributions are generally not deductible and qualified Roth distributions can be tax-free.

How to Start Investing

There is no universal investing strategy. A useful starting process is to understand your financial position and then match your investment choices to your goals and time horizon.

1
Define your goal

Identify what you're investing for, such as retirement, a long-term purchase or another financial goal.

2
Determine your time horizon

Consider when you expect to need the money. A longer horizon can change how you evaluate market fluctuations.

3
Build your cash foundation

Consider emergency savings and high-priority financial obligations before committing money to investments.

4
Learn about investment types

Understand stocks, bonds, funds, fees, risk and diversification before choosing investments.

5
Choose an appropriate account

Depending on your goal, this might include a taxable brokerage account or a retirement account such as a 401(k) or IRA.

6
Invest consistently and review

Track your contributions, costs and allocation and review your plan as your goals or circumstances change.

Common Investing Mistakes to Avoid

Investing without a goal

Your investment choices should have a purpose. A retirement portfolio and money needed for a near-term expense may require different considerations.

Ignoring fees

Investment expenses can reduce returns over time. Review expense ratios, account fees, trading costs and other charges that may apply.

Putting everything into one investment

Concentrating your money in one company or narrow area can expose you to greater concentration risk.

Expecting guaranteed returns

Investments can lose value. Be cautious of claims that promise unusually high or guaranteed returns with little or no risk.

Making decisions based only on past performance

Past performance does not guarantee future results. Consider the investment's underlying strategy, costs, risks and role in your overall plan.
