Analyzing Investment Performance with Alpha & Beta

Alpha and beta provide key insights into whether the active management of an investment strategy is truly adding value or merely adjusting the strategy’s exposure to risk. Understanding alpha and beta can help you assess whether a strategy is outperforming on a risk-adjusted basis.

What is Beta?

Beta measures the sensitivity of a strategy to market movements, which is the most common way to assess the systematic risk of a strategy compared to its benchmark. If the strategy returns move perfectly in sync with the benchmark return, then the strategy’s beta, as compared to that benchmark, is one (i.e., they are perfectly correlated). A beta greater than one means that the strategy is more sensitive (or volatile) than its benchmark while a beta less than one means it is less sensitive (less volatile) than its benchmark. A beta of zero means that the strategy is uncorrelated to the benchmark, while a negative beta means that it is negatively correlated with the benchmark. We will explain this more, but first let’s discuss how it works.

How to Calculate Beta

Beta is calculated as the covariance of the strategy and the market (benchmark) divided by the variance of the market (benchmark).

If every time the benchmark goes up 1%, the strategy goes up 1.2%, and every time the benchmark goes down 1%, the strategy goes down 1.2%, then the beta is 1.2. This means that the portfolio has increased its systematic risk (perhaps through adding leverage, but otherwise replicating the index). In this case, the portfolio manager has increased the strategy’s systematic risk and volatility as compared to the benchmark, but the manager has not “added alpha.” This strategy will outperform on the upside but will underperform on the downside.

Conversely, if every time the benchmark goes up 1%, the strategy goes up 0.8%, and every time the benchmark goes down 1%, the strategy goes down 0.8%, then the beta is 0.8. This means that the portfolio has decreased its systematic risk (perhaps through adding cash, but otherwise replicating the index). In this case, the portfolio manager has decreased the strategy’s systematic risk and volatility as compared to the benchmark and, as a result, the strategy is expected to underperform the benchmark on the upside and outperform on the downside.

Betas can also be negative; in which case the strategy is negatively correlated with the benchmark and would move in the opposite direction. For example, we would expect a strategy with a beta of -0.5 to go down 0.5% for every 1% increase in the benchmark. Betas can also be zero, indicating that the strategy’s movements are uncorrelated with the movements of the benchmark. Market neutral strategies generally strive to have a beta of zero to eliminate systematic risk from the management of the strategy. This is often achieved through a mix of long and short positions.

Beta vs. Standard Deviation

When analyzing performance, there are two types of risk: systematic and unsystematic risk.  Beta is a measure of systematic risk (i.e., market risk) and standard deviation is a measure of total risk. While beta is focused on correlation with the market or the strategy’s benchmark, standard deviation is focused on the variability of returns. This variability is a combination of systematic risk (market risk) and unsystematic risk (company-specific risk).

Both measures can be used in assessing risk-adjusted returns. Beta is used as the denominator in the Treynor Ratio, which measures how much excess return is generated per unit of systematic risk and is used to show the volatility the investment adds to a fully diversified portfolio. Standard deviation is used as the denominator in the Sharpe Ratio, which helps investors understand their returns as compared to the total risk of the portfolio. In contrast with Treynor, Sharpe is often used to compare fully diversified strategies against each other. For more information on systematic risk verses total risk, check out our article on Investment Performance & Risk Statistics.

What is Alpha?

Jensen’s alpha measures how much the strategy outperformed its expected return, with the expected return determined based on the Capital Asset Pricing Model (CAPM).

How to Calculate Alpha

To determine if the portfolio manager has “added alpha,” you can calculate Jensen’s alpha for the strategy. Using CAPM, the expected return is determined by the risk-free rate plus the beta-adjusted benchmark return. Specifically:

Jensen’s Alpha is then determined by subtracting the expected return from the actual return. Specifically:

If the portfolio manager is truly “adding alpha” (through stock selection, over/underweighting sectors, etc.) and not just increasing systematic risk in their active management, then the strategy’s Jensen’s alpha should be positive.

A positive Jensen's Alpha means the manager is consistently beating the market. A negative Jensen's Alpha means the manager is consistently under-performing. Demonstrating positive alpha over a sustained period of time demonstrates to clients and prospects of the strategy that the active investment decisions made by the portfolio manager resulted in an increased return without increasing systematic risk.

It is important to note that Jensen's Alpha is part of a regression and usually is accompanied by t-statistics and p-values to test significance levels. In other words, looking at Alpha without testing for statistical significance should be used with caution. If Alpha is positive but not statistically significant, it may not actually mean the manager outperformed on a risk-adjusted basis.

Why it's Important to Understand Alpha and Beta

Alpha and beta are widely used statistics that help managers of active investment strategies demonstrate their skill. Comparing strategy returns to benchmark returns without accounting for risk will not provide the full picture. Adjusting for systematic risk will help isolate the return achieved from increasing exposure to the market versus the return that is achieved through investment decisions that increased return without increasing systematic risk exposure.

Adjusting for total risk, rather than only for systematic risk is also important when demonstrating skilled active management. As mentioned earlier, check out Longs Peak’s articles on Investment Performance & Risk Statistics as well as the Sharpe Ratio and the Sortino Ratio to learn more about this.

From Compliance to Growth: How the GIPS® Standards Help Investment Firms Unlock New Opportunities

For many investment managers, the first barrier to growth isn’t performance—it’s proof.
When platforms, consultants, and institutional investors evaluate new strategies, they’re not just asking how well you perform; they’re asking how you measure and present those results.

That’s where the GIPS® standards come in.

More and more investment platforms and allocators now require firms to comply with the GIPS standards before they’ll even review a strategy. For firms seeking to expand their reach—whether through model delivery, SMAs, or institutional channels—GIPS compliance has become a passport to opportunity.

The Opportunity Behind Compliance

Becoming compliant with the GIPS standards is about more than checking a box. It’s about building credibility and transparency in a way that resonates with today’s due diligence standards.

When a firm claims compliance with the GIPS standards, it demonstrates that its performance is calculated and presented according to globally recognized ethical principles—ensuring full disclosure and fair representation. This helps level the playing field for managers of all sizes, giving them a chance to compete where it matters most: on results and consistency.

In short, GIPS compliance doesn’t just make your reporting more accurate—it makes your firm more credible and discoverable.

Turning Complexity Into Clarity

While the benefits are clear, the process can feel overwhelming. Between defining the firm, creating composites, documenting policies and procedures, and maintaining data accuracy—many teams struggle to find the time or expertise to get it right.

That’s where Longs Peak comes in.

We specialize in simplifying the process. Our team helps firms navigate every step—from initial readiness and composite construction to quarterly maintenance and ongoing training—so that compliance becomes a seamless part of operations rather than a burden on them.

As one of our clients put it, “Longs Peak helps us navigate GIPS compliance with ease. They spare us from the time and effort needed to interpret what the requirements mean and let us focus on implementation.”

Real Firms, Real Impact

We’ve seen firsthand how GIPS compliance can transform firms’ growth trajectories.

Take Genter Capital Management, for example. As David Klatt, CFA and his team prepared to expand into model delivery platforms, managing composites in accordance with the GIPS standards became increasingly complex. With Longs Peak’s customized composite maintenance system in place, Genter gained the confidence and operational efficiency they needed to access new platforms and relationships—many of which require firms to be GIPS compliant as a baseline.

Or consider Integris Wealth Management. After years of wanting to formalize their composite reporting, they finally made it happen with our support. As Jenna Reynolds from Integris shared:

“When I joined Integris over seven years ago, we knew we wanted to build out our composite reporting, but the complexity of the process felt overwhelming. Since partnering with Longs Peak in 2022, they’ve been instrumental in driving the project to completion. Our ongoing collaboration continues to be both productive and enjoyable.”

These are just two examples of what happens when compliance meets clarity—firms gain time back, confidence grows, and new business doors open.

Why It Matters—Compliance as a Strategic Advantage

At Longs Peak, we believe compliance with the GIPS standards isn’t a cost—it’s an investment.

By aligning your firm’s performance reporting with the GIPS standards, you gain:

  • Access to platforms and institutions that require GIPS compliant firms.
  • Credibility and trust in an increasingly competitive landscape.
  • Operational efficiency through consistent data and documented processes.
  • Scalability to support multiple strategies and distribution channels.

Simply put: compliance fuels confidence—and confidence drives growth.

Simplifying the Complex

At Longs Peak, we’ve helped over 250 firms and asset owners transform how they calculate, present, and communicate their investment performance. Our goal is simple: make compliance with the GIPS standards practical, transparent, and aligned with your firm’s growth goals.

Because when compliance works efficiently, it doesn’t slow your business down—it helps it reach further.

Performance reporting has two common pitfalls: it’s backward-looking, and it often stops at raw returns. A quarterly report might show whether a portfolio beat its benchmark, but it doesn’t always show why or whether the results are sustainable. By layering in risk-adjusted performance measures—and using them in a structured feedback loop—firms can move beyond reporting history to actively improving the future.

Why a Feedback Loop Matters

Clients, boards, and oversight committees want more than historical returns. They want to know whether:

·        performance was delivered consistently,

·        risk was managed responsibly, and

·        the process driving results is repeatable.

A feedback loop helps firms:

·        define expectations up front instead of rationalizing results after the fact,

·        monitor performance relative to objective appraisal measures,

·        diagnose whether results are consistent with the manager’s stated mandate, and

·        adjust course in real time so tomorrow’s outcomes improve.

With the right discipline, performance reporting shifts from a record of the past toa tool for shaping the future.

Step 1: Define the Measures in Advance

A useful feedback loop begins with clear definitions of success. Just as businesses set key performance indicators (KPIs) before evaluating outcomes, portfolio managers should define their performance and risk statistics in advance, along with expectations for how those measures should look if the strategy is working as intended.

One way to make this tangible is by creating a Performance Scorecard. The scorecard sets out pre-determined goals with specific targets for the chosen measures. At the end of the performance period, the manager completes the scorecard by comparing actual outcomes against those targets. This creates a clear, documented record of where the strategy succeeded and where it fell short.

Some of the most effective appraisal measures to include on a scorecard are:

·        Jensen’s Alpha: Did the manager generate returns beyond what would be expected for the level of market risk (beta) taken?

·        Sharpe Ratio: Were returns earned efficiently relative to volatility?

·        Max Drawdown: If the strategy claims downside protection, did the worst loss align with that promise?

·        Up- and Down-Market Capture Ratios: Did the strategy deliver the participation levels in up and down markets that were expected?

By setting these expectations up front in a scorecard, firms create a benchmark for accountability. After the performance period, results can be compared to those preset goals, and any shortfalls can be dissected to understand why they occurred.

Step 2: Create Accountability Through Reflection

This structured comparison between expected vs. actual results is the heart of the feedback loop.

If the Sharpe Ratio is lower than expected, was excess risk taken unintentionally? If the Downside Capture Ratio is higher than promised, did the strategy really offer the protection it claimed?

The key is not just to measure, but to reflect. Managers should ask:

·        Were deviations intentional or unintentional?

·        Were they the result of security selection, risk underestimation, or process drift?

·        Do changes need to be made to avoid repeating the same shortfall next period?

The scorecard provides a simple framework for this reflection, turning appraisal statistics into active learning tools rather than static reporting figures.

Step 3: Monitor, Diagnose, Adjust

With preset measures in place, the loop becomes an ongoing process:

1.     Review results against the expectations that were defined in advance.

2.     Flag deviations using alpha, Sharpe, drawdown, and capture ratios.

3.     Discuss root causes—intentional, structural, or concerning.

4.     Refine the investment process to avoid repeating the same shortcomings.

This approach ensures that managers don’t just record results—they use them to refine their craft. The scorecard becomes the record of this process, creating continuity over multiple periods.

Step 4: Apply the Feedback Loop Broadly

When applied consistently, appraisal measures—and the scorecards built around them—support more than internal evaluation. They can be used for:

·        Manager oversight: Boards and trustees see whether results matched stated goals.

·        Incentive design: Bonus structures tied to pre-defined risk-adjusted outcomes.

·        Governance and compliance: Demonstrating accountability with clear, documented processes.

How Longs Peak Can Help

At Longs Peak, we help firms move beyond static reporting by building feedback loops rooted in performance appraisal. We:

·        Define meaningful performance and risk measures tailored to each strategy.

·        Help managers set pre-determined expectations for those measures and build them into a scorecard.

·        Calculate and interpret statistics such as alpha, Sharpe, drawdowns, and capture ratios.

·        Facilitate reflection sessions so results are compared to goals and lessons are turned into process improvements.

·        Provide governance support to ensure documentation and accountability.

The result is a sustainable process that keeps strategies aligned, disciplined, and credible.

Closing Thought

Markets will always fluctuate. But firms that treat performance as a feedback loop—nota static report—build resilience, discipline, and trust.

A well-structured scorecard ensures that performance data isn’t just about yesterday’s story. When used as feedback, it becomes a roadmap for tomorrow.

When you're responsible for overseeing the performance of an endowment or public pension fund, one of the most critical tools at your disposal is the benchmark. But not just any benchmark—a meaningful one, designed with intention and aligned with your Investment Policy Statement(IPS). Benchmarks aren’t just numbers to report alongside returns; they represent the performance your total fund should have delivered if your strategic targets were passively implemented.

And yet, many asset owners still find themselves working with benchmarks that don’t quite match their objectives—either too generic, too simplified, or misaligned with how the total fund is structured. Let’s walkthrough how to build more effective benchmarks that reflect your IPS and support better performance oversight.

Start with the Policy: Your IPS Should Guide Benchmark Construction

Your IPS is more than a governance document—it is the road map that sets strategic asset allocation targets for the fund. Whether you're allocating 50% to public equity or 15% to private equity, each target signals an intentional risk/return decision. Your benchmark should be built to evaluate how well each segment of the total fund performed.

The key is to assign a benchmark to each asset class and sub-asset class listed in your IPS. This allows for layered performance analysis—at the individual sub-asset class level (such as large cap public equity), at the broader asset class level (like total public equity), and ultimately rolled up at the Total Fund level. When benchmarks reflect the same weights and structure as the strategic targets in your IPS, you can assess how tactical shifts in weights and active management within each segment are adding or detracting value.

Use Trusted Public Indexes for Liquid Assets

For traditional, liquid assets—like public equities and fixed income—benchmarking is straightforward. Widely recognized indexes like the S&P 500, MSCI ACWI, or Bloomberg U.S. Aggregate Bond Index are generally appropriate and provide a reasonable passive alternative against which to measure active strategies managed using a similar pool of investments as the index.

These benchmarks are also calculated using time-weighted returns (TWR), which strip out the impact of cash flows—ideal for evaluating manager skill. When each component of your total fund has a TWR-based benchmark, they can all be rolled up into a total fund benchmark with consistency and clarity.

Think Beyond the Index for Private Markets

Where benchmarking gets tricky is in illiquid or asset classes like private equity, real estate, or private credit. These don’t have public market indexes since they are private market investments, so you need a proxy that still supports a fair evaluation.

Some organizations use a peer group as the benchmark, but another approach is to use an annualized public market index plus a premium. For example, you might use the 7-year annualized return of the Russell 2000(lagged by 3 months) plus a 3% premium to account for illiquidity and risk.

Using the 7-year average rather than the current period return removes the public market volatility for the period that may not be as relevant for the private market comparison. The 3-month lag is used if your private asset valuations are updated when received rather than posted back to the valuation date. The purpose of the 3% premium (or whatever you decide is appropriate) is to account for the excess return you expect to receive from private investments above public markets to make the liquidity risk worthwhile.

By building in this hurdle, you create a reasonable, transparent benchmark that enables your board to ask: Is our private markets portfolio delivering enough excess return to justify the added risk and reduced liquidity?

Roll It All Up: Aggregated Benchmarks for Total Fund Oversight

Once you have individual benchmarks for each segment of the total fund, the next step is to aggregate them—using the strategic asset allocation weights from your IPS—to form a custom blended total fund benchmark.

This approach provides several advantages:

  • You can evaluate performance at both the micro (asset class) and macro (total fund) level.
  • You gain insight into where active management is adding value—and where it isn’t.
  • You ensure alignment between your strategic policy decisions and how performance is being measured.

For example, if your IPS targets 50% to public equities split among large-, mid-, and small-cap stocks, you can create a blended equity benchmark that reflects those sub-asset class allocations, and then roll it up into your total fund benchmark. Rebalancing of the blends should match there balancing frequency of the total fund.

What If There's No Market Benchmark?

In some cases, especially for highly customized or opportunistic strategies like hedge funds, there simply may not be a meaningful market index to use as a benchmark. In these cases, it is important to consider what hurdle would indicate success for this segment of the total fund. Examples of what some asset owners use include:

  • CPI + Premium – a simple inflation-based hurdle
  • Absolute return targets – such as a flat 7% annually
  • Total Fund return for the asset class – not helpful for evaluating the performance of this segment, but still useful for aggregation to create the total fund benchmark

While these aren’t perfect, they still serve an important function: they allow performance to be rolled into a total fund benchmark, even if the asset class itself is difficult to benchmark directly.

The Bottom Line: Better Benchmarks, Better Oversight

For public pension boards and endowment committees, benchmarks are essential for effective fiduciary oversight. A well-designed benchmark framework:

  • Reflects your strategic intent
  • Provides fair, consistent measurement of manager performance
  • Supports clear communication with stakeholders

At Longs Peak Advisory Services, we’ve worked with asset owners around the globe to develop custom benchmarking frameworks that align with their policies and support meaningful performance evaluation.
