ESG Investing Without Sacrificing Returns: How Values-Based Portfolios Are Built

When the Rockefeller Brothers Fund (RBF) announced in September 2014 that it was divesting from fossil fuels, the timing was almost too neat. The fund had been built with the Standard Oil fortune. The family stewarding that fortune had decided the way it was invested needed to reflect what the family now believed. What followed was less dramatic than the critics predicted. Over the next five years, the RBF’s portfolio returned an average of 7.76% annually, beating a 70/30 benchmark that still included coal, oil, and gas.

Many families hesitate to align their portfolios with their values because they expect a financial trade-off. That hesitation is understandable. It traces back to a real pattern in early Environmental, Social, and Governance (ESG) products, where narrow exclusion screens applied to concentrated fund structures underperformed in certain periods. The lesson from that era is about how those portfolios were built, not whether values and returns can coexist. When ESG screening is applied at the portfolio level, the performance gap disappears.

The Performance Trade-Off Assumption Comes From How Early ESG Products Were Constructed

Early ESG investing relied almost entirely on negative screening. It excluded certain sectors like tobacco and fossil fuels. It shrank the investment universe and called it “values-aligned.” The problem was concentration.

Removing entire sectors without adjusting for the resulting factor exposure left many early ESG funds overweight in a narrow slice of the market. When those sectors underperformed, the funds lagged. That lag became the data point critics cited, and it stuck.

Well-constructed ESG portfolios operate differently. Screens are applied across a broad investment universe. The construction process then accounts for the factor exposures each exclusion creates. The goal is a portfolio that reflects the family’s values while maintaining the diversification long-term returns rely on. Discipline governs any well-built portfolio. The values layer adds specificity to the process, but it doesn’t change the underlying standard.

How Negative and Positive Screening Work Inside a Portfolio

ESG screening at the portfolio level is more granular than fund-label investing suggests. Two approaches are in active use, and most sophisticated portfolios combine them.

Negative screening removes sectors or companies that conflict with the family’s values. The screen is defined by the family and reviewed as the portfolio changes over time.

Positive and best-in-class screening takes a different approach. Instead of removing sectors entirely, this approach selects companies with strong environmental, social, or governance practices. The portfolio reflects the family’s values through what it holds. Some sectors written off by broad exclusion screens contain companies that pass rigorous ESG criteria. Best-in-class screening finds them.

Combining both approaches, defined by the family before construction begins, is what separates a values-aligned portfolio from one that simply carries an ESG label. The result reflects the family’s actual criteria across every position it holds.

What the Research Says About ESG Factors and Portfolio Risk

The performance debate in ESG investing has generated academic research over the past decade. The most consistent finding is that strong ESG factors correlate with lower regulatory and reputational risk. That correlation contributes to more stable earnings profiles over time.

A widely cited meta-analysis by Friede, Busch, and Bassen in the Journal of Sustainable Finance and Investment reviewed approximately 2,200 individual ESG performance studies. Roughly 90% of those studies found a relationship between ESG criteria and financial performance, and a large majority showed the relationship was neutral or positive. Poor outcomes clustered in studies using narrow or poorly built screens.

The practical implication for investment management and portfolio construction is direct. Performance differences stem from sector concentration and construction quality. ESG portfolios with clearly defined screens and values-based diversification don’t sacrifice return potential.

How Kirk Capital Builds and Monitors a Values-Based Portfolio

At Kirk Capital Advisors, the values conversation happens before the portfolio construction conversation. A family defines its exclusion criteria and positive priorities. That definition gives Kirk Capital’s advisory team the specific criteria to build against. The resulting portfolio reflects those values precisely.

Screens are applied at the portfolio level rather than through ESG-labeled funds alone. ESG-labeled funds often carry higher expense ratios and limited tax-loss harvesting flexibility. They may include factor exposures the family didn’t anticipate. Building screens directly into the portfolio preserves control over costs and tax efficiency, and it determines how the portfolio actually behaves.

Once built, the portfolio is monitored for drift over time. Companies change. Industries shift. A company that passed the family’s screens at the start may not pass the same criteria five years later. Ongoing monitoring keeps the portfolio aligned with the family’s current values.

The Family’s Definition of Values Comes Before Any Portfolio Decision

ESG has no universal definition. What qualifies as values-aligned investing varies from family to family. One family’s priorities may center on environmental criteria. Another family’s focus might be on governance or labor practices. A portfolio built from a fund manager’s interpretation of ESG reflects that manager’s values. The family’s own values may not appear anywhere in the construction.

Portfolio-building starts with the family’s own definition. Families need to name the sectors or behaviors to exclude, the positive criteria that matter, and what they want the portfolio to stand for. Every construction decision follows from that. The KIRK Confidence Experience℠ is built around this sequence.

The bottom line? The performance trade-off in ESG investing is a portfolio construction problem. Poorly built portfolios underperform. Well-built ones track the market. Families who get this right define their values first, apply screens at the portfolio level, and monitor for drift over time.
