Boston, MA, USA September 19, 2007

An extensive study from Celent compares and ranks execution venues for Nasdaq stocks.

In a study that analyzes data for over 8 billion orders and over 300 billion shares in the Nasdaq and the NYSE, Celent compares and ranks the leading market centers in a new report by Octavio Marenzi, CEO of Celent.

In terms of the overall ranking, Instinet and NYFIX were found to achieve the best prices, with Nasdaq MC in third place. Lehman Brothers, previously one of the slowest execution venues, shot to first place in terms of speed.
