Activist Investor Interventions: A Path to Stock Performance Improvement
Recent research published in the Financial Analysts Journal suggests that activist investor interventions with small, newly public companies can have a positive impact on their stock performance. The study, titled “Shareholder Activism in Small-Cap Newly Public Firms,” by Emmanuel R. Pezier and Paolo F. Volpin, showcases how engagements with these companies led to 8% to 10% in cumulative abnormal returns. The key takeaway is that these returns were attributed to the activism itself, not stock picking.
In a conversation with Pezier, an associate scholar at Saïd Business School, University of Oxford, conducted for the CFA Institute Research and Policy Center, we delve deeper into the implications of this study and its significance in the world of finance.
