The NYSE Group Inc. announced that the U.S. Securities and Exchange Commission has cleared the way for full implementation of its NYSE Hybrid Market.

The SEC recently issued final approval of several pending rule filings allowing for full Phase III implementation of the new system, the NYSE said. The exchange will begin immediate expansion of the rollout process to the complete list of NYSE-traded issues beginning with 399 securities on Dec. 6.

The final Phase III rollout, which is expected to conclude in early January 2007, will mark the inclusion of all eligible NYSE listed issues available for trading in the Hybrid Market. The system is supposed to combine the market quality benefits of specialist and floor broker expertise with the speed and certainty of electronic executions.

The exchange will announce securities added during this process on the NYSE’s website as they enter the system.
