Bloomberg Study Finds Automated Equity Trading Results in Improved Performance

Press Release from Bloomberg Professional Services

NEW YORK, March 13, 2024 /PRNewswire/ -- Bloomberg today announced the results of a study that analyzed performance and execution costs from trades automated using Rule Builder (RBLD), Bloomberg's multi-asset automated trading solution. The research, which examined data from Bloomberg's Transaction Cost Analysis (BTCA) solution, found that both U.S. and European equity trading desks that used RBLD saw an overall performance (combination of automated and manual orders) increase  of 30% and 36% respectively, compared to Non-RBLD firms trading manually.

The study evaluated anonymized data from BTCA covering 23 million orders between January 1, 2022, and December 31, 2023. Specifically, the data analyzed included the arrival price or Implementation Shortfall benchmark, normalized by the weighted average based on each trade's notional value in USD. Implementation Shortfall refers to the difference between the decision price and the final execution price of a trade.

Analysis of U.S equity trades showed that orders that used RBLD outperformed manual orders by 38%. In European equity markets, orders using RBLD showed a 68% performance improvement compared to manual orders. The use of RBLD also resulted in less performance variation, which provides traders with more consistent and predictable results.

The study also found that RBLD can help better predict and manage trade costs. Analyzing orders based on their size compared to the average daily volume (ADV) showed that orders using RBLD consistently performed better than manually routed orders in both U.S. and European equity markets across a range of order sizes. In the US, automated orders using RBLD outperformed manual orders by 25% (0-0.5% ADV), 35% (0.5-1% ADV), and 47% (1.0-2.0% ADV). Similarly, in Europe, the trend showed outperformance by 51% (0-0.5% ADV), 39% (0.5-1% ADV), and 84% (1.0-2.0% ADV).
