@Parmnparsley - Stocks and bonds are both investments, but they are very different. Stocks are shares of ownership in the equity of a company. Bonds are loans to companies or governments, essentially the same as ownership of a country or company’s debt.
Bond’s have a set return, or coupon rate, that is paid when the bond matures. Bonds are usually safer than stocks, mainly because they are paid before stocks if the company fails. Organizations can default on bonds though, making some bonds safer than other bonds. Most investors consider U.S. treasury bonds safe investments, but this low risk also means lower returns.
The article and Babalaas distinguished the difference between a few types of stocks. Stocks are usually higher risk than bonds, but this also means the reward is better.
