Benchmark To Show Winning Returns

By David Allison AAA

How has your investment performance been for the last one, five and 10 years? Unfortunately, when asked that question, investors often provide casual observations like "OK", or "pretty good". The truth is that most investors have no idea how they are doing because they have no benchmark against which they compare their investment portfolio's performance.

When was the last time you played golf, tennis, basketball, or any other competitive sport? Did you walk away saying we did "OK" compared to the other team? No - you kept score! Shouldn't you be keeping score the same way when investing? The most efficient way to do this is to employ an investment benchmark and compare it to the performance of your investment portfolio. Read on to find out how to do this.

Setting Benchmarks
What's an appropriate benchmark? A good investment benchmark will have the following characteristics:

  1. It will be appropriate and will be agreed upon in advance.
    The benchmark you select should be consistent with your risk/return objectives and constraints. There should also be an understanding in advance between you and the investment manager that the agreed upon benchmark is representative of the manager's underlying investment strategy and that he or she takes responsibility for the risk-adjusted performance of your portfolio as compared to your benchmark. (For related reading, see Personalizing Risk Tolerance.)

  2. It will be investable.
    You should be able to forgo active management and invest in the benchmark. Do not compare your investment performance to a benchmark that you cannot replicate in the real world. Benchmarks that contain a lot of small, illiquid securities or that have high turnover should be scrutinized. A good way to judge whether your benchmark can be replicated in the real world is to see if there is an index fund or an exchange-traded fund (ETF) available that matches your selected benchmark.

  3. It will be properly weighted.
    If you are using an index as a benchmark, you should make sure that the index is weighted to reflect a passive (buy-and-hold) investment strategy. Market cap weighted indexes, such as the S&P 500 Index, do not require constant rebalancing and are consistent with a passive investment strategy. Other popular weighting schemes, such as price-weighting or equal-weighting, require constant rebalancing and are not consistent with a passive investment strategy. (For more insight, see Market Cap, Equal Weight And Fundamental Indexing.)

  4. It will be transparent and easy to understand.
    The benchmark you use should have clear, published rules governing things like the criteria used for adding and deleting holdings from the benchmark.It should also have historic holdings and performance data available. This will allow you and your investment manager to better match a benchmark to your investment goals; it will also assist the manager with the portfolio management process.

Different Types of Investment Benchmarks
There are several different types of benchmarks that should be considered when looking for the right one against which to compare your portfolio.

  1. Absolute Benchmark: This is simply a rate of return objective. An example of this would be a minimum required rate of return or actuarial return. This type of benchmark is easy to monitor and understand, and can be agreed upon in advance. The downside is that it can lack passive investable alternatives.

  2. Style Specific Indexes: These indexes represent a specific area or manager discipline in an asset class category. An example of these would be large or small cap and value or growth indexes. Because these indexes are concentrated in one area, their exposure to certain sectors or stocks may be too narrow. This narrow exposure may cause some investment managers to deem these style-specific indexes inappropriate as benchmarks.

  3. Broad Market Indexes: These Indexes reflect a broad market, be it a domestic stock, bond index, or a global stock. Most people are familiar with these indexes. Some examples would be the S&P 500, Russell 3000, Lehman Aggregate, the MSCI World and the MSCI Europe, Australasia and Far East (EAFE) indexes. Many investment managers' disciplines are not this broad, which could make the benchmark a poor match for their investment strategies.

  4. Investment Manager Universe Average: This is the average investment manager performance from a broad universe of managers with the same discipline. This type of benchmark is good for comparing your investment manager to his or her peers, but it is not investable because the average investment manager in the universe is not known in advance. This type of benchmark is prone to survivorship bias as poor performing managers/mutual funds are always fired/closed over time.

  5. Custom Benchmark: This benchmark is made up of one or more indexes or groups of securities weighted to reflect an investor's optimal asset allocation, style mix, or investment strategy. For example, a portfolio with a 60% U.S. stock and 40% U.S. government bond split could be assigned a custom benchmark made up of 60% of the Standard and Poor's 500 Index and 40% of the Lehman U.S. Treasury Index. Custom benchmarks are great for investors with more complex investment objectives and constraints and investment managers with narrow niche strategies. Custom benchmarks can be time-consuming to build and rebalance, but are usually worth the effort.

Conclusion
Comparing the risk-adjusted performance of your investment portfolio to an investment benchmark helps quantify the value that you or your investment manager add by pursuing active investment management. With the recent proliferation of indexes and the creation of ETFs, there are now many combinations of benchmarks that can be matched to reflect your investment objectives. Because investing should always be viewed as a marathon and not a sprint, you need to have patience in trying to best your chosen benchmark - and be prepared to be humbled if it proves to be tough to beat.
