Investing is when you put your money "to work for you," another way to think of investing is when you put your money "at risk." You buy an investment like a stock or bond with the hope that its value will increase over time. Although investing comes with the risk of losing money, should a stock or bond decrease in value, it also has the potential for greater returns than you'd receive by putting your money in a bank account.
