What is the difference between a warrant and an option traded by the CBOE?
解释：
In a warrant, a fixed number of options are issued by a company and the company guarantees that it will satisfy investors when they exercise the options. In an exchange-traded option, the number of options expands as there are more trades and contracts as traders close out their positions. The Options Clearing Corporation administers margins and ensures that investors are able to exercise the options they own.
