Abstract: The objective of this research paper is to investigate the association between internal Corporate Governance (CG) mechanisms and stock price volatility in Egypt as an emerging market. The paper investigates the impact of ownership structure and board structure as internal CG mechanisms on stock price volatility. Data are analyzed using a two-way fixed effects model, a one-step dynamic panel data model, and a panel weighted least squares model. The study concluded that ownership concentration has a negative influence on volatility. Interestingly, an inverted U-shaped relationship between the percentage of ownership by the greatest shareholder and volatility is evidenced. Managerial ownership also showed a negative influence on volatility. As for board structure mechanisms, the findings show that both board size and frequency of board meetings negatively influence volatility, whereas board independence has a positive impact.
