Properties of a Valid Investment Benchmark
In order to determine the success of an investment strategy it must be compared to a benchmark. A valid benchmark should possess the following qualities:
- Unambiguous - the identities and weights of securities or factor exposures should be clearly defined
- Investable - could the investment be placed in the benchmark itself rather than being managed actively
- Measurable - the return should be readily available or calculable
- Appropriate - the benchmark should reflect the manager’s style or expertise
- Reflective of current investment opinions - an equity manager has opinions (positive or negative) on equities but may have no opinions on fixed income securities. The latter should not be included in a valid benchmark.
- Specified in advance - all interested parties should know the benchmark and its constituents before an evaluation period begins
- Owned - the manager is willing to accept responsibility for performance relative to the benchmark
