A new study by global trading network Liquidnet has found significant differences in the volatility of block trades in the Australian market minutes before execution, depending on where trades are executed. Higher volatility implies information leakage, which may cause a significant impact on performance for institutional investors.
Since FINRA began publishing ATS volume, brokers and other analysts have used the data in various ways to rate or rank the various trading venues. However, we believe that none of the analysis presents this data in a way that is relevant to asset managers. To help fill this void, Liquidnet has developed the Dark Pool Value Index that ranks each ATS based on the factors that are most meaningful to an institutional investor (market share, market share symbol rank, and trade size by symbol).
