So you’ve started earning a little money—and maybe you’re wondering what to do with it. Saving is smart, but if you want that money to grow, you’ll need to invest it.
Where to start? How about the same place the pros start: with the two traditional investment types: stocks and fixed income, or bonds.
Buying a stock means buying a small piece of a company. Really—when you own shares of stock, you own part of the business, which means you have a claim on a portion of all future earnings. If that company grows and becomes more valuable, your shares go up in value too. That’s called capital appreciation. Some companies also send out part of their profits to shareholders as dividends.
Of course 
 there’s risk. Stock prices can go up or down depending on how the company performs—or how investors think it might perform. That’s the trade-off for potential growth.
And then there are bonds and other fixed-income investments. With fixed-income, instead of owning part of a company, you’re lending your money out. A corporate bond is a loan to a company. A municipal bond is a loan to a city or state. Treasury bonds, notes, and bills are loans to the federal government. And a certificate of deposit (or CD) is basically a loan to a bank.
In return for your loan, you’ll get interest payments—usually at a set rate—and when the bond or CD matures, you get your original investment back. Bonds and other fixed-income investments tend to be more stable than stocks, but they’ve historically offered lower returns. And there’s still risk, especially if the borrower can’t pay you back (a situation called default).
That’s why investors rarely go all-in on just one thing. Diversification means spreading your money across different investments—stocks, bonds, and beyond. That helps balance out the ups and downs of the market to help manage your risk.
Investing might seem intimidating, but learning the basics—and staying tuned to Britannica Money—can put you on the right track 
 and keep you moving toward your financial goals.
