The Chicago Board of Options Exchange. Want to buy options? No need to go to the Windy City. The CBOE is an exchange that lets you buy and sell options. They sell more than a million contracts a day, since they are pretty much the biggest options exchange around. All the options sold there are the basic calls and puts and all are American-style (which means you don’t have to wait until the day of expiration to exercise your option). Created in 1973, the CBOE is also busy creating e-trading and other financial tech products.
