Stocks and bonds are two of the most common building blocks in investing, but they represent fundamentally different relationships. A stock generally represents ownership in a company, while a bond generally represents money lent to a government, municipality or company.
What owning stock means
Stockholders participate in the financial results of a business through changes in share price and, for some companies, dividends. Stock returns can be strong over long periods, but prices can be volatile and losses can be substantial.
What owning a bond means
A bond is a debt security. The issuer generally promises to pay interest according to stated terms and repay principal at maturity. Bonds differ widely in credit quality, maturity, interest-rate sensitivity and other risks.
Risk and return differ
Stocks are generally associated with greater short-term price volatility and higher growth potential. High-quality bonds are often less volatile than stocks, but they are not risk-free. Bond values can fall when interest rates rise, and issuers can default.
Income characteristics
Some stocks pay dividends, but companies can reduce or eliminate them. Many bonds make scheduled interest payments, although payment structures vary. Investors should not treat either form of income as universally guaranteed.
Why portfolios may hold both
Because stocks and bonds can respond differently to market and economic conditions, combining asset classes may help investors align a portfolio with their goals, time horizon and risk tolerance. The appropriate mix is personal rather than universal.
