DEI commitment linked to S&P 500 outperformance

A UC Berkeley researcher has published findings suggesting S&P 500 companies that maintained diversity, equity and inclusion programmes outperformed peers that scaled back or abandoned them, even as political pressure mounted to abandon DEI initiatives.

The study arrives at a moment when US corporate DEI has become a flashpoint. The incoming Trump administration has signalled opposition to DEI policies, and some companies have already responded by rolling back programmes, citing legal and political risk.

The Berkeley research counterarguments that narrative. Rather than a liability, the data suggests sustained DEI commitment correlated with stronger financial performance – though the research does not establish causation. The professor behind the work advises companies to distinguish between performative DEI (surface-level commitments without resource or structural change) and substantive diversity initiatives tied to business outcomes.

This creates a practical tension for boards: political pressure is real and carries reputational and legal risk; so does abandoning programmes if the correlation between DEI and performance holds. The question isn't whether DEI "works" – it's whether companies have the conviction to defend the business case when the political wind shifts.

The findings matter most for institutional investors and audit committees weighing governance trade-offs. If DEI programmes genuinely correlate with performance, then abandoning them on political grounds becomes a fiduciary question, not just an HR one.

What would shift a company's calculus: stronger peer pressure from investors, or clearer legal protection from discrimination claims tied to active DEI?

Is conceding to the Trump administration on DEI a recipe for business success?
