In a new report, Execution Quality in the NYSE Market, Celent analyzes over 12 billion orders over the period of July 1, 2012 to September 30, 2012. In total, the report by Anshuman Jaswal, senior analyst with Celent’s Securities & Investments group, measures and ranks 155 market participants according to their execution speed and prices obtained for incoming orders.
