EOBs continue to dominate the Nasdaq market for the covered shares. But their cumulative share has declined slightly from 78% to 77% since the last survey in March 2014, while that of market-makers has grown from 21% to 22% during this period.

In a new report, Execution Quality in the NASDAQ Market, Celent analyzes over 18 billion orders over the period of June 1, 2014 to August 31, 2014. The report, authored by Anshuman Jaswal, a senior analyst with Celent’s Securities & Investments practice, measures and ranks 130 market participants according to their execution speed and prices obtained for incoming orders.

BATS Exchange, NYSE Arca, and Two Sigma Securities are the leading venues, as shown in the Figure below. Some of the other leading market centers include Citadel Derivatives, G1 Execution Services (formerly E*Trade Capital), EDGA Exchange, and BATS-Y Exchange. Different types of market centers, such as market-makers and EOBs, often tend to be grouped in clusters, as indicated by the color coding.

The overall ranking for EOBs in Nasdaq is shown in Table 1. The leading EOBs in terms of price improvement are BATS Exchange, NYSE Arca, and EDGX Exchange. Comparing the speed of execution, BATS Y-Exchange, NYSE Arca, and Nasdaq MC are the leading market centers. Similarly, overall across the two categories of price and speed, NYSE Arca, BATS Y-Exchange, and EDGX & EDGA Exchanges seem to be the better performers among the major EOBs in the current survey.

Comparing the ranking and comparison of the leading market makers in Table 2, Interactive Brokers, G1 Execution Services, and Citadel Derivatives are the best performers for price improvement. Comparing for the average speed of execution, BNY Capital Markets, Knight Securities, and G1 Execution Services are among the better performing firms. Overall, G1 Execution Services, Knight Securities, and UBS Securities are the leading market makers across price and speed rankings.
