CBOE retains exclusivity

摘要

Cook County Circuit Judge William Maki ruled on July 8 that the Chicago Board Options Exchange (CBOE) would continue to have exclusive licenses on its index options products.rnThe battle goes back to 2006 when the International Securities Exchange (ISE) moved to list stock index options on the S&P 500 (SPX) and Dow Jones Industrial Average (DJX), both of which CBOE held exclusive licenses to list.
