This study aims to analyze the effect of firm size, profitability, leverage, and free float ratio on stock price volatility in companies listed in the IDX30 index on the Indonesia Stock Exchange during the 2020–2024 period. A quantitative approach is employed using panel data regression analysis with Eviews 12 software. The research sample consists of 12 companies selected through purposive sampling. The results show that partially, firm size and profitability have a significant effect on stock price volatility. In contrast, leverage and free float ratio do not have a significant effect. However, simultaneously, all four independent variables significantly influence stock price volatility. These findings provide empirical contributions to investors and capital market participants by identifying key fundamental factors that influence stock price fluctuations. %Z Dr. Darmawan, SPd., MAB
