CBOE stands for the Chicago Board Options Exchange. It's like a big store where people can buy and sell options. Options are like special coupons that allow you to buy or sell something, like a stock or a commodity, at a certain price.
People use options for different reasons. Some people use them to protect themselves if the price of something goes down. Others use them to try to make money by guessing if the price of something will go up or down in the future.
The people who work at CBOE help make sure that everyone is playing fair and following the rules when they buy and sell options. They also help people know what options are available to buy and sell, and what the prices are. This helps everyone make informed decisions and trade safely.
