What is the stock market?

Companies need money to grow, and there’s a way for them to get it: the stock market. They can sell a little piece of their company, called a share or stock, to regular people. If the company grows, those people get to keep some of the money it makes. Of course, there’s no guarantee that a company will grow — that’s what makes putting your money in the stock market risky. On this week’s episode, we’ll explain how it all works with the help of some Dutch spice traders, comfy sneakers, a bull ... and a bear! Got a money problem?
