New York, May 8, 2006 – NYSE Group, Inc.

NYSE InfoTools offers investors the capability to actively monitor the composition of executed order flow in real-time and compare that with historic norms, making this product a one-of-a-kind information tool.  By improving transparency and investors’ ability to assess NYSE market trends on a real-time, end-of-day and archived basis, NYSE InfoTools is a unique information product for in-depth trading volume analysis of the world’s largest and most liquid marketplace.  The initial release of the InfoTools menu of products consists of:

ReTracSM
ReTrac, or Retail Tracker, is available as a real-time datafeed providing investors the ability to identify retail share volume as it is executed on the NYSE and allowing investors to determine the amount of volume, on a stock-by-stock basis, that is attributable to retail order flow.  The ReTrac end-of-day file contains a summary of that day’s ReTrac activity, and for each stock it further categorizes the retail volume into buys and sells.

ProTracSM
ProTrac, or Program Tracker, is available as a real-time datafeed providing investors the ability to identify program trading share volume as it is executed on the NYSE and allowing investors to determine the amount of program trading volume, on a stock-by-stock basis, that is attributable to program trading order flow.  The ProTrac end-of-day file contains a summary of that day’s program trading activity, and for each stock it further categorizes the program trading activity into the amount that was executed as part of index arbitrage program trading strategies from that of all non-index arbitrage program trading strategies.
