When you’re first getting into investing, it’s natural to wonder whether your portfolio is actually performing well. However, “good” performance is relative and your returns only have meaning when compared to something else. That’s where benchmarking comes in.
Benchmarking is simply the process of comparing your investment performance to a relevant standard. And while it can sound technical, the basics are easy to understand and useful, whether you're a new investor or refining your long-term strategy.
What Is a Benchmark?
A benchmark is a reference point or a market index that represents the type of assets you hold. It serves as the measuring stick for determining whether your portfolio is underperforming, matching or outperforming the broader market.
Three of the most commonly used benchmarks for the U.S. stock market include:
- The S&P 500: An index that tracks the performance of about 500 large-cap U.S. stocks.
- The Dow Jones Industrial Average: Tracks the performance of the largest 30 companies, also commonly referred to as “Blue Chip” stocks.
- The Nasdaq Composite: This index tracks the performance of over 3,000 companies, heavily focused on technology.
If your portfolio is mostly U.S. stocks, comparing your performance to the S&P 500 offers a clearer picture than comparing it to a bond index.
Why Benchmarking Matters
Benchmarking is a simple way to understand how well your portfolio is really performing. Without a clear comparison point, it’s difficult to know whether your returns reflect strong decision-making or just broader market movement. By using a benchmark, you gain an objective view of your strategy’s performance.
- Evaluate Your Performance. It’s easy to feel confident when your portfolio is up, but benchmarking helps you determine whether your returns are due to skill, market movements or luck. This lens can help you refine your strategy and understand how your approach stacks up against the broader market.
- Identify Gaps or Imbalances. If your portfolio consistently trails its benchmark, it could signal issues worth looking into. You might be taking on too much concentration in one sector or holding assets that don’t complement one another. Benchmarking brings those blind spots into focus so you can make informed adjustments.
- Stay Focused on Long-term Strategy. Benchmarks help you tune out the noise and stay grounded in a strategy aligned with your goals and risk tolerance. This long-term perspective is essential for avoiding emotional decisions and staying disciplined as markets fluctuate.
How to Choose the Right Benchmark
Choosing the right benchmark is essential because not all comparisons are meaningful. A benchmark should reflect the types of assets you hold and the level of risk you’re comfortable with. When your benchmark aligns with your portfolio, your performance evaluation becomes more accurate.
- Match the asset mix. A benchmark should mirror the overall structure of your portfolio. For example, if your allocation is 60% U.S. stocks and 40% bonds, a benchmark with similar blend can provide the most accurate comparison.
- Use more than one benchmark if needed. Portfolios that include international stocks, small caps or real estate often can’t be correctly evaluated using a single index. Using multiple benchmarks allows you to pinpoint the performance of each asset type and understand where the strengths or weaknesses are.
- Avoid mismatches. Using a benchmark that doesn’t reflect your portfolio’s components can lead to misleading assumptions. An overly aggressive benchmark may make your performance appear weaker than it truly is, while an overly conservative one can create an overly positive sense of success. Aligning your benchmark with your portfolio’s actual characteristics ensures that comparisons remain accurate.
How Often Should You Benchmark Your Portfolio?
Benchmarking works best when you follow a consistent schedule. However, make sure they’re realistic. Frequent check-ins can create unnecessary stress, while too little oversight can cause you to miss trends that matter. Reviewing your performance quarterly or annually provides a balanced view of how your portfolio is tracking over time. Finding the right cadence helps you stay informed without becoming overwhelmed.
