Abstract: This study investigates the effect of firm characteristics on stock price volatility (SPV) of listed firms in Nigeria, utilising longitudinal research design and data from 40 firms across the manufacturing, financial services, and oil and gas sectors between 2011 and 2022. Using generalised linear models (GLM), the results indicate varied associations between these variables and SPV. DPR, EVOL, EPS, and BDI have a significant negative impact on SPV, highlighting the role of dividend consistency, stable earnings, and independent governance in reducing stock price fluctuations. Conversely, LEV is positively associated with SPV, suggesting that higher leverage amplifies volatility. Meanwhile, SIZE, ASG, and ROA exhibit no significant effect on SPV during the study period. The results underscore the importance of profitability, financial stability, and governance in mitigating investment risks. Firms are advised to optimise their capital structures, maintain consistent dividend policies, and strengthen board independence to minimise SPV and attract investors.

Keywords: stock price volatility; SPV; dividend payout ratio; earnings volatility; earnings per share; EPS; firm size; asset growth; return on assets; generalised linear models; GLM; Nigeria.
