Stocks vs Bonds: What's the Difference?

Learn the basics of stocks and bonds, and how they work together in your investment portfolio.

What Are Stocks?

When you buy stocks (also called shares or equities), you're buying a small piece of ownership in a company. If the company does well, your shares become more valuable. Many companies also pay dividends – a share of their profits distributed to shareholders. Stocks offer high growth potential but come with more risk because share prices can be volatile.

What Are Bonds?

Bonds are loans you make to governments or companies. In return, they promise to pay you interest (the coupon) and return your capital at the end of the term (maturity). UK government bonds are called gilts. Corporate bonds are issued by companies. Bonds are generally less risky than stocks but offer lower potential returns. They provide steady income and help stabilize portfolios.

How Stocks Make Money

You profit from stocks in two ways: capital growth (share price increases) and dividends (income payments). Over the long term, most stock returns come from capital growth, though dividend income is valuable too, especially in retirement. Stock returns vary hugely year-to-year but have historically delivered strong long-term growth.

How Bonds Make Money

Bonds provide returns through regular interest payments and potential capital gains. If you hold a bond to maturity, you get your money back plus all the interest. If you sell before maturity, the bond's value might have changed based on interest rate movements. When interest rates fall, existing bonds become more valuable, and vice versa.

Risk Differences

Stocks can fall 50% or more during severe market crashes, though they've always recovered given time. Individual companies can fail completely. Bonds from stable governments (like UK gilts) are very safe but offer lower returns. Corporate bonds carry more risk than government bonds but pay higher interest to compensate. The trade-off is always risk versus return.

Why Hold Both?

Most investors hold both stocks and bonds because they behave differently. When stocks fall dramatically, bonds often hold steady or even rise in value. This balance reduces portfolio volatility without giving up too much growth. A classic balanced portfolio is 60% stocks and 40% bonds, though the right mix depends on your age, goals, and risk tolerance.

Stocks for Growth, Bonds for Stability

Think of stocks as the growth engine and bonds as the stabilizer. Younger investors with decades until retirement can afford higher stock allocations because they have time to ride out volatility. As you approach retirement, increasing bond allocations provides stability and reduces the risk of needing to sell stocks during a market crash.

How to Invest in Each

You can buy individual stocks and bonds, but most investors use funds. Stock funds (index trackers or actively managed) provide instant diversification across hundreds of companies. Bond funds similarly spread risk across many bonds. Using funds is simpler, cheaper, and less risky than trying to pick individual securities yourself.
