NYSE & CBOE to Lay Down Their Swords This is an intriguing idea that I hadn't been aware of before. The NYSE & CBOE have a llong history of fighting bitterly then making up, and this might be another example of that. Imagine what the resulting exchange would look like, and how dominant it would be. An NYSE/Euronext/CBOE exchange might would be a powerhouse in stocks, options AND futures. They would definitely be the dominant exchange in the U.S. and would even have enough muscle to take on the CBOT/CME monstrosity.
