Quick Answer
A benchmark must match the portfolio's investment style, asset class, and risk profile, or the comparison misleads. Benchmark types include market index, peer group, absolute return, and custom blend, alongside common named indices such as the S&P 500, Russell 2000, MSCI EAFE, and the Bloomberg U.S. Aggregate Bond Index.
Choosing the right benchmark matters: the wrong one can make a mediocre manager look brilliant or a skilled manager look terrible. This page covers benchmark types, common named benchmarks, index weighting methods, and how to select the right benchmark for a given portfolio.
What Are the Benchmark Types?
- Market index benchmark compares performance to a representative index, such as the S&P 500 or Russell 2000
- Peer group benchmark compares a manager's performance to other managers in the same investment category, such as ranking among large-cap growth managers
- Absolute return benchmark targets a fixed return regardless of market conditions, such as CPI plus 3%. Common for hedge funds and liability-driven portfolios (like pension funds) that must meet a specific return obligation
- Custom blend benchmark combines multiple indices weighted to match a portfolio's actual asset allocation, such as 60% S&P 500 and 40% Bloomberg U.S. Aggregate Bond Index for a 60/40 balanced portfolio
What Are the Common Equity Benchmarks?
| Benchmark | What It Covers | Weighting |
|---|---|---|
| S&P 500 | 500 large-cap US stocks | Market-cap weighted |
| Russell 2000 | 2,000 small-cap US stocks | N/A |
| Wilshire 5000 | Total US equity market | N/A |
| MSCI EAFE | Developed international markets (ex-US, ex-Canada) | Market-cap weighted |
| NASDAQ Composite | All NASDAQ-listed stocks | N/A |
| Dow Jones Industrial Average (DJIA) | 30 large-cap US stocks | Price-weighted |
| Consumer Price Index (CPI) | Inflation | N/A (used for real return comparison) |
Key points:
- Market-cap weighted means larger companies have more influence on the index's return
- Price-weighted means higher-priced stocks have more influence, regardless of company size
- The Wilshire 5000 is the broadest US equity benchmark, often used as a proxy for the total US stock market
- The MSCI EAFE excludes the US and Canada, making it the standard international developed-market benchmark
- The CPI is used as a benchmark for comparing real (inflation-adjusted) returns
Exam Tip: Gotchas
- The DJIA is price-weighted, NOT market-cap weighted. The S&P 500 is market-cap weighted. If the exam asks which index uses price weighting, the answer is the Dow Jones Industrial Average.
What Is the Common Fixed-Income Benchmark?
- Bloomberg U.S. Aggregate Bond Index ("the Agg"): covers the broad investment-grade US bond market. This is the standard fixed-income benchmark.
How Do Index Weighting Methods Work?
| Method | How It Works | Example |
|---|---|---|
| Market-cap weighted | Larger companies have more influence | S&P 500, MSCI EAFE |
| Price-weighted | Higher-priced stocks have more influence | DJIA |
| Equal-weighted | All components weighted equally | S&P 500 Equal Weight Index |
How Do You Select the Right Benchmark?
The benchmark must match the portfolio's investment style, asset class, and risk profile. Using an inappropriate benchmark is misleading and overstates or understates manager performance.
- A small-cap portfolio should be measured against the Russell 2000, not the S&P 500
- An international equity fund should be measured against MSCI EAFE, not a domestic index
- A bond portfolio should be measured against the Bloomberg Aggregate, not an equity index
Exam Tip: Gotchas
- The exam will test whether you can select the appropriate benchmark for a given portfolio. A manager of a small-cap value fund should NOT be compared to the S&P 500 (large-cap blend). Always match the benchmark to the portfolio's style and asset class.
What Should You Check on Exam Day?
- The four benchmark types: market index, peer group, absolute return, and custom blend
- Absolute return benchmarks (such as CPI plus 3%) target a fixed return, common for hedge funds and liability-driven portfolios
- Custom blend benchmarks combine indices to match a portfolio's actual allocation
- The DJIA is price-weighted; the S&P 500 and MSCI EAFE are market-cap weighted
- Match the benchmark to the portfolio's investment style, asset class, and risk profile: small-cap to Russell 2000, international to MSCI EAFE, bonds to the Bloomberg U.S. Aggregate
