Investors treat chief executives who attended private school as a safer bet, even though the companies they run perform no better than those led by state-educated counterparts. A new study exposes what amounts to a perception gap between how financial markets price in leadership pedigree and what that pedigree actually delivers.
Researchers at the University of Surrey analyzed decades of US corporate data and found that stock volatility at firms led by privately educated CEOs ran about 5% lower than at comparable companies with state-educated leaders. The catch: there was no meaningful difference in how these two groups of executives actually performed, made decisions, or handled crises.
The lower volatility reflects investor confidence in private school backgrounds, not superior business outcomes. According to the study, published in the European Financial Management journal, financial markets appear to be confusing privilege with competence when faced with uncertainty about a leader's true capabilities.
"People like to think markets are purely rational, but our findings show that perception still plays a powerful role," said Dr Christos Mavrovitis, a senior lecturer in finance and accounting at Surrey and co-author of the research. "A chief executive's background can shape how investors feel about a company, even when it has no real impact on how that company is run."
The effect weakens over time as investors accumulate actual performance data. It also diminishes at firms with heavy analyst coverage or substantial institutional ownership, suggesting that better-informed investors rely less on social signals and more on hard evidence.
The research gains weight against the backdrop of UK corporate leadership. A 2025 report by the Sutton Trust, a social mobility charity, found that among FTSE 100 chief executives educated in Britain, only 34% attended state comprehensive schools. Nearly 37% went to private institutions. The disparity is starker for board chairs. This comes despite private school education accounting for just 7% of the general UK population.
The findings suggest that investor psychology, not operational reality, drives market perceptions of leadership quality tied to educational background. Companies run by privately educated executives appear less risky to the market simply because they look more stable to investors predisposed to trust them.
Author James Rodriguez: "This study nails something every newsroom knows but few can prove: markets reward the signaling of competence as much as actual competence, and that gap leaves room for advantage that has nothing to do with performance."
