Nasdaq announced that it has completed the implementation of all securities into its new trading platform, SuperMontage.

The transfer over to the new system began on October 14. Now, all 3,950 securities listed on Nasdaq trade on SuperMontage. “Our new trading platform, SuperMontage, illustrates how Nasdaq technology can offer trading opportunities more efficiently, quickly and transparently to investors,” said Wick Simmons, chairman and CEO. “It offers the most comprehensive picture of any market ever for all market participants.”

Rick Ketchum, president and deputy chairman, Nasdaq, said, “SuperMontage has been very well-received by the securities industry. Our next generation securities platform is designed to provide investors, traders and our listed companies with the fairest, fastest, most liquid and dependable market possible.”

Participants in SuperMontage today include the entire market making community — approximately 300 firms; ECNs including Archipelago, Bloomberg Tradebook, BRUT, The Track ECN, Attain, and NextTrade; and The Chicago Stock Exchange.

Nasdaq says that in its early stages, the new trading platform is demonstrating greater depth of liquidity and use of the reserve feature by market participants. In one sample study based on the November 11-13 time period, aggregate depth has increased more than 50%. Execution speed has improved to about 1/10th of a second. 93% of marketable orders are fully or partially executed, up from 63% pre-SuperMontage.

SuperMontage was launched on October 14 with five securities. The remaining securities were transitioned over the following seven weeks, culminating in the final group of stocks being implemented on December 2.
