Buy-side Firms Use TCA to Measure Execution Performance

By Brian Mitchell, Dale Brooksbank, Ian Firth
“Does your firm use TCA to measure execution performance and if yes, how effective a tool do you find it?”
Ian Firth, Aviva Investors, responds
Aviva Investors both subscribes to and supports the use of Transaction Cost Analysis (TCA). We acknowledge there are limitations, both with available systems and market data. We aim to identify trends and ways to improve our trading strategies, and we have spent a great deal of time and resources to continually improve the process we operate. The key to efficient TCA is accurate data and efficient time stamping. This will demonstrate where within the cycle of the order there are inefficiencies. All of our equity trades are subject to review, although a small number may fall out due to the fact specific markets and benchmarks in those markets are not provided/supported.
Trades are loaded on a daily basis and there is commitment from dealers and our in-house execution analyst to ensure that as much information as possible is attached to clearly identify specific trades. Regular reports with details and exceptions are sent to portfolio teams and management to monitor the ongoing performance of dealers, brokers and execution venues. We compare against various benchmarks, with Implementation Shortfall (IS) being our primary benchmark. There is greater discipline in recording all attributes, whether price limits, volume restrictions or direction from the fund manager, in order to identify exceptions and where appropriate identify these trades.
We have seen, and continue to see, an improving trend to our execution capability. We are able to easily identify outliers and explain the reasons for these. Improving results have helped with our profile and we have been able to distribute the results of our trading capability to end clients. We have received positive feedback from our clients, both direct and end, due to the results and the knowledge applied to explain said processes and results.
Brian Mitchell, Gartmore, responds
Yes; Gartmore’s monitoring and analysis of dealing efficiency is aimed at helping to reduce trading costs, identifying potential deficiencies and helping to ensure that our investment processes are in line with the highest market standards for buy-side best execution.
As part of our effort to ensure cost effective execution, we perform detailed TCA and within that we focus, amongst other things, on both the explicit and implicit costs of trading. Explicit costs include equity commission rates, ticket charges and local taxes. Implicit costs, which can account for more than 85% of overall implementation costs, include: (i) market impact (the cost of the bid/offer spread plus the price movement in excess of the bid/offer spread needed to trade the required volume immediately); and (ii) opportunity cost (the performance impact of not instantaneously completing the execution of an order).
While we use broker-led TCA offerings, (across our cash equities, PT and Algo business flows), we do not solely rely on them, given the potential lack of impartiality. It is also difficult to compare trades transacted by competing brokers, as most will inevitably use differing methodologies. We currently use an independent TCA service to help analyse in detail the true impact of equity trade implementation on client accounts and to analyse Broker / Dealer performance, sending them all trade data from our OMS on a weekly basis.
