Chicago Board Options Exchange to Enter Stock Trading; Partners With Four Firms in Launching CBOE Stock Exchange, LLC

CHICAGO, IL and NEW YORK, NY -- (MARKET WIRE) -- July 27, 2006 --The Chicago Board Options Exchange (CBOE) announced today at a press conference in New York City that it is partnering with Interactive Brokers Group, LLC; LaBranche & Co Inc.; Susquehanna International Group, LLP; and VDM Specialists, LLC to launch the CBOE Stock Exchange, LLC (CBSX), a new securities trading marketplace.

The CBOE Stock Exchange will feature a Hybrid market model that will combine elements of both screen and floor-based trading; and provide a new venue for the trading of New York Stock Exchange, NASDAQ Stock Market, and American Stock Exchange listed securities. CBSX is expected to launch in early 2007, pending final regulatory approval from the Securities and Exchange Commission (SEC).

Hybrid Market Model

CBOE Stock Exchange will employ a Hybrid Trading System, similar to the highly successful Hybrid environment currently being utilized for options trading at CBOE, the largest options exchange in the United States. Hybrid combines the point-and-click functionality of screen-based trading with the versatility of floor trading, providing for a best-of-both-worlds trading experience. CBOE's Hybrid model was created to provide flexibility for all customers, including those who prefer to have their orders negotiated in an open-outcry setting, as well as those who seek a screen-based trading experience. CBOE's Hybrid Trading System has been highly successful in the extremely competitive U.S. options industry. In 2006, CBOE market share of total industry volume has increased seven percentage points during the first six months of the year, climbing from 30% in January to 37% at the end of June.

"We're privileged to be partnering with some of the largest, most respected trading firms in the securities industry to launch this exciting new venture. Collectively, these firms represent significant portions of volume at our nation's securities exchanges and the expertise and liquidity they will bring to the CBSX marketplace will be invaluable," said William J. Brodsky, Chairman and Chief Executive Officer of the Chicago Board Options Exchange. "This venture recognizes the proven success of CBOE's Hybrid market model, which enables professional brokers to represent customer orders in an open outcry environment that is integrated with a state-of-the-art electronic system offering sub-second execution. We believe the CBOE Stock Exchange and its Hybrid market model can extend these same advantages to the stock world by providing it with this economical and proven alternative market."

DPMs & Market Makers

Each stock that is traded on CBSX will have an assigned Designated Primary Market Maker (DPM). CBSX DPMs will be located at a designated trading post on the CBOE trading floor and will have the primary responsibility for maintaining a fair and orderly market in the stock. Additional liquidity will be provided by multiple competing Remote Market Makers (RMMs) who will have the ability to stream quotes and trade electronically from any location; greatly expanding the number of potential participants in the trading universe.

Order Handling

It is anticipated that CBSX will feature a matching algorithm that emphasizes price/time priority. CBOE and CBSX floor brokers will represent orders in the open outcry portion of the Hybrid Trading System. Unlike traditional Specialist roles, CBSX DPMs will not act as agents on behalf of orders.


Products available for trading at CBSX will include the most active 2500 New York Stock Exchange, NASDAQ Stock Market, and American Stock Exchange listed stocks, as well as exchange traded funds (ETFs) and other listed securities.

Trade Engine

CBOEdirect, the highly versatile and incredibly robust trading platform developed by CBOE that currently serves as the trade engine that powers CBOE's Hybrid Trading System; OneChicago, the all-electronic single stock futures exchange that is a joint venture between CBOE, the Chicago Mercantile Exchange (CME) and Chicago Board of Trade (CBOT); and the all-electronic CBOE Futures Exchange (CFE), will serve as the trade engine for CBSX. Built entirely in-house by CBOE, CBOEdirect was constructed to be extremely flexible and easily adaptable for a variety of uses.


Access to CBSX will be assigned through a trading permit program. Any qualified members of CBOE will automatically receive a trading permit and be granted access to CBSX. Non-CBOE members will be issued a permit to trade at CBSX upon completion of a standard membership-application process.

Business Model

CBOE Stock Exchange, LLC is a facility of the Chicago Board Options Exchange, Incorporated. Ownership of CBSX will be divided between CBOE and the partner firms, with approximately 50% of the venture owned by CBOE and 50% owned by the partner firms.

Market Regulation

CBOE's Regulatory Services Division will provide all market surveillance services for CBSX. CBSX will be regulated by the Securities and Exchange Commission (SEC).
