The research method applied was the panel data model with fixed effects (with or without a robust estimator) and random effects.Findings: Determinants that have a major and statistically significant impact on the analyzed dependent variables are: the unemployment rate, the real interest rate, the beta in Sharpe’s Single-Index Model and the implied volatility of the S&P 500 index and the EURO STOXX50 index.Research limitations/implications: Insights about the strength and direction of influence of these variables on stock return volatility are a valuable addition to the existing body of knowledge that investors resort to when making decisions relating to the capital market.Limitations: The main limitation of this study lies in the fact that the results of the analysis apply solely to the banking sector.Originality/value: Insights about the strength and direction of influence of these variables on stock return volatility are a valuable addition to the existing body of knowledge that investors resort to when making decisions relating to the capital market.
