Cboe''s Weekly Market Recap: June 6th To 10th Exciting developments occurred on the Cboe Global Markets Inc. (BATS: CBOE ) this week. Lending a throwback to its earliest days, Cboe celebrated the grand opening of its new trading floor in Chicago, where it was founded in 1973 as the first listed options exchange in the United States. Located in the historic Chicago Board of Trade (CBOT) Building, Cboe''s new trading floor occupies more than 40,000 square feet on the seventh and eighth floors, with double-height floor-to-ceiling windows that overlook Chicago''s historic LaSalle Street financial district. The exciting initiative is a mesh of past and present, combining the open outcry trading methods that defined the early 1990s with today’s cutting-edge technology. "Our new and enhanced trading floor offers a vibrant, technology-driven environment that seamlessly integrates both open outcry and electronic trading mechanisms to provide our customers a truly unrivaled, world-class trading experience. We believe this dynamic new space will serve our customers and investors well — now and for years to come,” said Chris Isaacson, executive vice president and chief operating officer at Cboe Global Markets.
