Investing Through Benchmarking

How are your investments performing? What is happening to the principal value of your portfolio when interest rates change? What are the appropriate risk and returns that can be expected for the types of funds you are investing? Did your portfolio perform up to expectations? How were these expectations derived and communicated? The answers to these questions and many more are an integral part of effective investment management. Benchmarking is the process that provides performance analysis and creates a method to communicate expectations and results.

Public fund investors are confronted with many challenges including uncertain cash flows, volatile interest rates, regulatory changes, and fiduciary responsibility. Public fund objectives require that liquidity needs be satisfied while preserving capital and simultaneously achieving market rates of return. Most governmental entity investment policies identify the objectives and the securities used to meet these objectives. However, seldom do such policies establish a process or a procedure to monitor risk and measure returns. Benchmarking is a step in the investment management process that addresses risk management, yield enhancement, and the monitoring of investment returns versus expectations.

What is a benchmark?

A benchmark is a composite of securities with specific maturity and asset class characteristics that represent a portion of the financial market universe. Investors can simulate the expected risk and return of various benchmarks to determine the most appropriate structure for their portfolio. A benchmark index has the following characteristics:

  1. Contains a composite of securities maintained within specific parameters
  2. Provides information
  3. Is rule-based, not managed
  4. Can be measured
  5. Remains relatively stable in regards to duration and asset allocation.

How do you use a benchmark?

Investors use benchmarks to assess the performance of their portfolio and to oversee incremental changes to that portfolio. Example of benchmarks. Many short-term public fund investors use the Treasury zero- to three-year index or the Treasury zero to five year , as a benchmark for core balances, because they reflect the maturity structure, quality, and market exposure consistent with their investment objectives and policy. These Treasury indices are a composite measurement of every U.S. Treasury note in the market from 1 day to three years or five years in maturity. ICE Bank of America Merrill Lynch provides the data.

History illustrates that, over longer periods of time, having investments exposed longer out on the yield curve results in greater returns, but this comes with a risk of periodic market price declines that must be considered when determining appropriate exposure. We believe the best risk adjusted returns for conservative investors with relatively low price volatility comes from this sector of the curve. In addition, the 1.4 year to 2 year average maturity of the index falls within the guidelines of most investment policies and is an appropriate exposure for public fund idle cash balances. It is important to note that this type of benchmark is appropriate for idle funds (core funds) not for funds needed for liquidity purposes (liquidity funds).

Decision-making Using a Benchmark

An investor’s portfolio structure is adjusted relative to the benchmark depending on the market outlook or the entity’s specific needs. We suggest establishing a minimum and maximum exposure (duration) around the benchmark as part of the strategy to achieve enhanced market rates of return. As new money is available, the maturity selection of the new investment would be dictated by the current and targeted overall portfolio exposure (duration) relative to the benchmark. Is outperforming the benchmark the key to this process? No. The key to the process is to establish a disciplined approach to placing investment funds out longer on the yield curve so as to enhance returns over longer periods of time, while controlling risk. The goal is not to significantly outperform the index, but to achieve the return of the index or enhance it by using conservative portfolio management tools. These tools may include the following:

  • Either being shorter or longer than the duration of the benchmark. An acceptable difference between the duration of the benchmark and the portfolio is predetermined. The greater the acceptable range around the duration of the benchmark, the greater the return variable.
  • Investing at a particular point on the yield curve. A barbell structure (combination one-year notes and three-year notes) will outperform a benchmark when the yield curve flattens and bullet structure (all two-year notes) will outperform a benchmark when the yield curve steepens.
  • Investing in asset classes outside the benchmark issues; e.g., adding U.S. agency obligations or asset backed securities to a generic U.S. Treasury portfolio. This tool should be considered after credit quality variation is taken into account.

Are there other benefits to benchmarking?

Yes. The benchmarking process provides a discipline to the investment management process and helps reduce the “shoot from the hip” syndrome to emotional swings in the market. But most importantly, it communicates to all the expected returns and risk associated with the portfolio based on the historical performance of the benchmark and the acceptable level of variance from the benchmark. This process will reduce the probability of results that are significantly outside an expected range, which should enhance the risk management process for those with fiduciary responsibilities.

Benchmarking provides the public fund investor with a clear sense of direction, accountability, and tools to balance risk and return. This disciplined strategy can be clearly communicated to pool participants, boards, and other interested parties. This increase in communication alone is a significant step in the development of the investment management process.

Investment advisors are available to assist internal investment officers in designing, managing, and reporting portfolio characteristics relative to the appropriate benchmark. Most public fund advisors are sensitive to implementing a cost beneficial relationship in providing these types of services.
