Values-aligned investing is growing because the problems driving it are growing. Climate change, resource depletion, and widening inequality are no longer future risks. They are present-day existential issues that threaten the livelihoods of billions.
The Intergovernmental Panel on Climate Change (IPCC) projects global warming of 2.7°C by 2100 under current policies — nearly double the Paris Agreement target of 1.5°C. Physical climate risk and carbon transition risk are now embedded in corporate valuations, insurance markets, and regulatory frameworks. Investors who exclude these factors from portfolio analysis are not insulated from them.
In response, interest in sustainable investing has grown massively, especially with Gen Z and Millennial investors. According to the Morgan Stanley Sustainable Signals Survey, 99% and 97% of GenZ and Millenial investors report interest in shifting capital to sustainable investing. With a $124 trillion intergenerational wealth transfer coming their way, this is a structural demand shift, not a cyclical trend.
Self-directed investors who want to act on these realities face a practical problem. Most screening tools available to retail investors rely on aggregate third-party ESG ratings that bundle unrelated factors into a single score. Ziggma provides a five-step workflow built on granular, company-level impact data to close this gap.

The performance evidence clearly counters the long-standing misconception that values-aligned investing entails sacrificing returns. With that notions dismissed, the practical question becomes how to implement values-aligned investing with the precision required to ensure a portfolio reflects actual values — not just labels.
The following five steps show how Ziggma gives self-directed investors the tools to screen, score, optimise, track, and measure impact across every holding.


The Ziggma stock screener filters by specific, measurable impact data. Aggregate ratings from MSCI and Sustainalytics bundle unrelated factors into a single composite score. A tobacco company with strong governance can outscore a clean-energy firm with weak lobbying disclosure. Ziggma filters by individual data points instead: carbon intensity, net-zero target date, Ziggma Fair Labour Score, and Ziggma Controversy Score. Available Ziggma themes include Climate Action, No Vice Stocks, Happy Employees, and Fossil-Fuel-Free. Each theme targets one measurable variable.
Use the Ziggma impact stock screener to build your initial shortlist.
Ziggma scores every holding on two independent dimensions: financial quality and real-world impact. The Ziggma Stock Score processes millions of fundamental data points. The Impact Score rates corporate behaviour across four dimensions: Climate Action, Sustainable Resource Use, Fair Labour Practices, and Accountability. Impact data is provided by ACA Ethos, Ziggma's impact data partner. Both scores appear side by side for every holding on the Ziggma platform.
For example, The Ziggma High Conviction 2026 model portfolio holds a Ziggma Score of 94 out of 100. LAUR (Laureate Education) and NVDA (NVIDIA) each score 100. KEYS (Keysight Technologies) scores 79 — the lowest in the portfolio and still above the quality threshold. The Ziggma Impact Score for the portfolio is 70. KEYS, NVDA, and NXT (Nextracker) achieve Profound Ziggma Impact status. MU (Micron Technology) is the only Mixed-impact holding.
The Ziggma Portfolio Optimizer rebalances any portfolio against multiple simultaneous objectives: a Ziggma Score floor, a Ziggma Impact Score floor, and a Ziggma Beta Risk Factor ceiling. This removes the need to screen alternatives manually.
The Ziggma High Conviction 2026 model portfolio carries a Ziggma Beta Risk Factor of 1.50x — above the market baseline of 1.0. The Ziggma Portfolio Checkup flags this automatically. The Ziggma Portfolio Optimizer can surface lower-beta alternatives while maintaining the portfolio's Ziggma Score of 95 and Ziggma Impact Score of 70.
The Ziggma free portfolio tracker links directly to brokerage accounts — including Robinhood, Fidelity, and Schwab — and syncs holdings automatically. Manual data entry is not required. Ziggma monitors the Ziggma Score, Ziggma Impact Score, and Ziggma Beta Risk Factor in real time. Multiple accounts consolidate into one dashboard.
The Ziggma High Conviction 2026 model portfolio is available as a virtual portfolio that any Ziggma user can save and track. It provides a live benchmark for self-directed investors building values-aligned portfolios. Account linking and virtual portfolios are available during the Ziggma 7-day free trial.
The Ziggma Portfolio Checkup delivers a full health assessment on one screen. Ziggma flags concentration risk automatically using the Herfindahl-Hirschman Index (HHI). The Ziggma Global Warming Potential (GWP) gauge shows the implied temperature pathway of a portfolio's holdings under current emissions trajectories. The Ziggma Controversy Score surfaces reputational risk alongside financial metrics.
The Ziggma High Conviction 2026 model portfolio registers a Ziggma GWP of 2.29°C. The Paris Agreement target is 1.5°C. The Ziggma Controversy Score is 39 out of 100, with 328 controversies tracked across the portfolio in the past two years.
Net-zero target dates appear holding-by-holding in the Ziggma Impact tab. Microsoft (MSFT) targets 2030. Keysight Technologies (KEYS) and Mastercard (MA) target 2040. AbbVie (ABBV) and Micron Technology (MU) target 2050. NVIDIA (NVDA), Nextracker (NXT), Laureate Education (LAUR), and Insulet (PODD) have not declared net-zero targets.
Aggregate ESG ratings from MSCI and Sustainalytics are the dominant data source for most impact-labelled investment products. These ratings measure the financial risk to a company from ESG factors — not the company's impact on the world. The distinction matters.
Two companies in the same sector can receive identical composite ratings for entirely different reasons. A fossil fuel company with strong governance and good lobbying disclosure can outscore a renewable energy firm with a weak compliance function. This is not an edge case. It is a structural feature of how composite ratings work.
Greenwashing risk is highest when investors rely on opaque composite scores without access to underlying data. An investor who excludes fossil fuels but holds a high-rated energy company deriving most of its revenue from oil extraction has not achieved their objective. They have held a label.
Ziggma uses ACA Ethos impact data — company-level measurements scored independently across Climate Action, Sustainable Resource Use, Fair Labour Practices, and Accountability. Nothing is bundled into a composite. The Ziggma Impact Score exposes each dimension separately for every holding. Investors can identify the source of any score and respond to it.
The case for values-aligned investing has moved beyond ethics. It is now a capital allocation thesis.
Companies that operate sustainably — reducing emissions, managing resources efficiently, treating employees and suppliers fairly — tend to demonstrate the operational discipline that drives long-term financial performance. The Schroders and Oxford Saïd Business School study found this connection is statistically significant and independent of traditional financial risk factors.
The $124 trillion intergenerational wealth transfer has the potential to redirect a meaningful share of global capital toward companies that meet the environmental and social standards of a new generation of investors. Companies that fail to adapt face simultaneous exposure: capital pressure from shifting investor preferences, regulatory pressure from climate disclosure requirements, and reputational pressure from increasing public transparency.
The aggregate effect of this reallocation stands to reward companies that operate sustainably and penalize those that do not. Self-directed investors who act early gain both the financial performance advantage identified in the research and the portfolio alignment they are seeking.
Ziggma provides the scoring, screening, and tracking infrastructure to make this shift with precision — through granular data-based scoring backed with an extensive set of empiriral data on corporate environmental and social performance.
