// eli5Imagine a lemonade stand that's so popular the owner wants to sell pieces of it to other kids. Each piece is called a stock. When you buy a stock, you own a tiny part of that business. If the lemonade stand makes more money, your piece becomes more valuable! The stock market is like a big marketplace where people buy and sell these pieces of companies all day long [1][3]. It started way back in 1602 when a big trading company in Amsterdam decided to let people own pieces of their business [2].
