Trade Ideas from Equity Sales Specialists Significantly Outperform Market in 2006



    FactSet Research Systems (NYSE: FDS) announced today that the
    latest figures from its Alpha Network database show ideas generated by
    equity sales personnel across the network produced a total return of
    19.1% in 2006, outperforming their benchmark by over 10%.

    These figures include all long and short recommendations as
    promoted to clients by the brokers using the Alpha Network, a leading
    alpha capture system designed to communicate trade ideas between the
    sell-side and their clients. Nearly 4,000 institutional salespeople
    globally use Alpha Network as their main channel for communicating and
    measuring investment ideas. While approximately 7,000 ideas are
    created per month, fund managers receive only those ideas targeted
    towards their own investment strategy, from only those brokers they
    have selected. Alpha Network also enables fund managers to measure the
    performance of individual brokers, overall or by sector, to identify
    the best performing brokers in their networks.

    "Most fund managers recognize a significant talent among brokers
    for generating alpha but don't have an effective way of capturing
    their ideas," says Henning Holter, Director of FactSet AlphaMetrics.
    "As our findings show, the Alpha Network strategy of fund managers
    selecting brokers, setting clear guidelines for recommendations, and
    systematically tracking and rewarding idea generation produces
    convincing alpha that may be translated into strong investment
    returns."

    The results are true across fund managers who use Alpha Network.
    Though managers differ on investment strategies and their chosen
    network of brokers, they commonly benefit from more focused and
    relevant ideas, leading to better performing recommendations. The
    system has produced equally impressive results for the equity sales
    personnel who submit ideas, as their performance and value are
    objectively captured and rewarded.

    "Using Alpha Network to promote their best ideas - with full
    transparency and recognition - seems to have a positive impact on
    brokers' focus and commitment to ideas," says Holter. "We believe this
    strategy is a major contributor to raising the quality of investment
    ideas and to ensuring that ideas are both actionable and relevant to
    clients."
