University of Strathclyde Leads Groundbreaking Analysis of UK Stock Market Dynamics
The University of Strathclyde has produced research that sheds new light on how wealth is generated in the British stock market. Academics at the institution’s Department of Accounting and Finance examined nearly five decades of data from UK-listed companies and uncovered a striking pattern of concentration in real wealth creation.
This work, led by Professor Jonathan Fletcher with co-author Michael O’Connell, forms part of the university’s ongoing commitment to rigorous, policy-relevant finance research. Strathclyde Business School continues to strengthen its reputation as a centre for excellence in accounting and finance education across the United Kingdom.
Background on the Research Team and Institution
Strathclyde Business School, based in Glasgow, is one of the United Kingdom’s established providers of business education. Its Department of Accounting and Finance delivers undergraduate, postgraduate and doctoral programmes that prepare students for careers in investment analysis, corporate finance and financial regulation.
Professor Jonathan Fletcher brings extensive expertise in empirical finance to the project. His research focuses on portfolio performance, asset pricing and market efficiency. Michael O’Connell, a researcher at the same department, contributed to the detailed data analysis that underpins the study.
The university’s location in Scotland places it at the heart of a vibrant higher-education landscape that supports both teaching excellence and applied research with national and international reach.
Scope and Methodology of the Study
The researchers analysed every stock listed on the London Stock Exchange, including the Alternative Investment Market and the former Unlisted Securities Market, between January 1975 and December 2024. They applied the methodology developed by US scholar Hendrik Bessembinder to measure real wealth creation—the excess return above what could have been earned in safer assets such as UK Treasury bills.
This approach allowed the team to isolate genuine value creation rather than nominal price movements. The study period spans major regulatory changes, including the 1986 Big Bang deregulation of the London Stock Exchange, providing a natural experiment for examining shifts in market behaviour.
Key Findings on Wealth Concentration
Across the full sample, only 3.1 per cent of stocks generated all the aggregate real net wealth created by the UK market. The total stood at more than £305 billion. Just 46.5 per cent of individual stocks produced positive real wealth creation over their lifetimes.
The top three contributors were Shell, BP and HSBC. The top ten stocks together accounted for a substantial share of the overall figure. Wealth creation became markedly more concentrated after the 1986 Big Bang, with small-capitalisation stocks playing an increasingly prominent role in recent sub-periods, including post-Brexit and post-Covid intervals.
In the pre-Big Bang era, the majority of stocks delivered higher real buy-and-hold returns than UK Treasury bills, indicating a broader distribution of positive outcomes. Post-deregulation, this pattern reversed for most companies.

Implications for UK Investors and Markets
The findings challenge conventional assumptions about stock-market investing. Rather than a broad field of steady performers, the market appears dominated by a small number of high-impact companies. This concentration has implications for portfolio construction, index-tracking strategies and the expectations placed on active fund managers.
Equal-weighted portfolios of the highest-wealth-creating stocks showed some performance benefits in the study, although value-weighted approaches did not. The results underscore the difficulty of stock selection and the importance of understanding long-term wealth-creation patterns.
UK universities, including Strathclyde, play a vital role in equipping future finance professionals with the analytical skills needed to navigate such market realities.
Contribution to Higher Education in Finance
Research of this nature directly enriches the curriculum at institutions such as the University of Strathclyde. Students in accounting and finance programmes gain exposure to cutting-edge empirical methods and real-world market data. Doctoral candidates can build on the dataset for further investigation into market efficiency, corporate governance and regulatory impacts.
The study also highlights opportunities for interdisciplinary collaboration between finance academics and colleagues in economics, law and data science—areas where UK higher-education providers increasingly seek to differentiate themselves.
Broader Economic and Policy Context
High concentration of stock-market wealth creation raises questions about capital allocation, corporate governance and the distribution of economic gains. Policymakers and regulators may consider these patterns when reviewing listing rules, disclosure requirements and investor-protection measures.
Strathclyde’s research contributes to an evidence base that informs debate within the UK financial-services sector and among professional bodies such as the Investment Association and the Financial Conduct Authority.
Future Research Directions and University Leadership
The University of Strathclyde continues to invest in data-intensive finance research. Future projects could extend the analysis to international markets, incorporate environmental, social and governance factors, or examine the role of institutional investors in driving concentration.
Such work reinforces the United Kingdom’s position as a global leader in financial research and education, attracting international students and fostering partnerships with industry.

Student and Career Opportunities
Graduates from Strathclyde’s finance programmes benefit from exposure to research that addresses live market questions. Roles in investment banking, asset management, equity research and regulatory bodies increasingly value candidates who understand long-term wealth-creation dynamics.
The university maintains strong links with employers across the UK financial sector, supporting placement opportunities and graduate employment outcomes.
Conclusion and Outlook
The University of Strathclyde’s study provides a clear, data-driven picture of how wealth has been created in the UK stock market over half a century. Its findings invite reflection on market structure, investment strategy and the role of higher education in advancing financial understanding.
As UK universities continue to produce world-class research, institutions such as Strathclyde demonstrate the value of sustained academic inquiry into the mechanisms that shape national prosperity.
