Your wealth is never neutral: How to build a portfolio with purpose and drive real additionality

Why your wealth is already shaping the world, even if you haven’t started investing for impact

Most wealth holders treat impact investing as an elective: a specialized “sleeve” of their portfolio they might get around to once the “real” financial strategy is settled. But money is never neutral. Whether you have an explicit strategy or not, your capital is already in the world, participating in the outcomes of the corporations you own (partially through shares or in full), or lend capital to. If you aren’t intentionally steering that influence, you could be endorsing a status quo that may actually contradict the very values you hold.

The recurring challenge for the next generation of wealth holders stems from a lack of clarity on how to bring good into the world. Sustainable finance is a noisy atmosphere, and it’s easier than ever to mistake a green (or rather, a greenwashed) portfolio for an impactful one. Our research at the Center for Sustainable Finance and Private Wealth (CSP) suggests that to bridge the gap between intention and action, investors like you can move past the comfort of ownership and embrace the discipline of additionality.

The fallacy of the green collector

The most common trap for impact-focused investors is conflating company impact with investor impact.

Company impact is the change in the world caused by a company’s activities, such as a pharmaceutical giant developing life-saving treatments.

Investor impact is the change you induce in that company’s behavior that would not have happened without your capital or engagement.

Consider a fund holding shares in a major pharmaceutical company like Gilead Sciences. While the company has a positive impact by treating HIV patients, your individual purchase of its shares from another investor on the public market likely does not result in a single additional patient receiving treatment. You are only buying the shares from another investor and there is a strong chance the company does not even know it. In this scenario, your company impact is high, but your investor impact is effectively zero.

To be a true impact investor, you must stop being a collector of “good” companies and start being a direct cause of “good” outcomes. Here are three research-backed tips to help you move from passive ownership to an operational blueprint for change.

Tip one: seek out additionality through growth

If you want your capital to be the primary engine of change, you must go where financial markets are least efficient. This is the principle of additionality: providing capital to impactful companies that really need it and cannot easily get it elsewhere.

The most compelling evidence for this is in private markets: venture capital, private equity and private debt. A classic example is Bill Gates’ 2013 investment in Impossible Foods. At the time, the company’s prospects were highly uncertain, and Gates provided vital capital that enabled its rapid initial growth. This investment went beyond “owning” a sustainable product and went on to enable a new market to scale. If you want to enable growth in a similar manner, look for small, young companies with intangible assets or those operating in underdeveloped financial markets.

Tip two: pursue coherence and stop “fooling yourself”

As the physicist Richard Feynman famously noted, “The first principle is that you must not fool yourself — and you are the easiest person to fool.” In wealth management, the easiest way to fool yourself is to maintain a “split personality” portfolio. That means investing for profit in one room and giving for impact in another.

True impact requires coherence: applying the same values and rules consistently across every dollar you own. This means holding your investments to the same rigorous standards as your grants. If you are accepting a financial loss for an investment that delivers an impact that would not pass your own grant committee, you are making an incoherent grant rather than being a true impact investor. The same applies to creating problems with traditional investments on one side, and aiming to clean them up with impact investments or giving on the other.  

By making trade-offs explicit and ensuring your investments are not funding the very problems your philanthropy is trying to solve, you stop leaving “impact value” on the table.

Tip three: harvest the low-hanging impact fruit

You do not have to divest from brown companies to have an impact. In fact, you can often cause more change by staying at the table through shareholder engagement. This is probably the most likely way to have any impact in public markets. Counter-intuitive to some, but true.

Research shows that active owners can drive meaningful improvements in ESG practices by focusing on low-hanging fruit, also known as the improvements that are realistic for a company to implement at a reasonable cost. For example, the asset manager Hermes EOS engaged with Sinopec, a major Chinese oil and gas company, to reduce methane leaks. This dialogue led to a program that saved roughly three million tons of carbon dioxide emissions in one year, which is an impact equivalent to the annual emissions of the entire Bahamas.

If you own public equities, go beyond voting your shares and ensure your asset manager is engaged in high-stakes, documented dialogues with management. Engagement funds do that for you.

Building your operational blueprint

Impact isn’t a feeling, and it certainly isn’t a lecture series. It is a disciplined, operational process. The gap between your intention and your action is where your potential to change the world currently sits.

At CSP, we built the Impact Investing for the Next Generation program to help wealth holders aged 20 to 55 cross that gap. This is a peer-led, conflict-free environment where you take the theory and move to action by building your own Investment Policy Statement (IPS) and joining a global community of investors doing the same work alongside you.
