In order to avoid uncertainty and risk in the stock market, it is very important to measure the factors affecting the volatility of stock returns. Research on the volatility of stock returns and investment risk has been carried out around several basic axes related to each other, i.e. the time periods of volatility, the consequences of the volatility of stock returns, its prediction and the factors affecting the volatility of stock returns. The purpose of this research is Identifying factors affecting stock return Volatility Using Meta-Synthesis Method. The research methodology is combined. In the qualitative part, based on the seven steps of Meta-Synthesis proposed by Sandelowski and Barroso (2007) in the time interval from 1980 to 2024, the most important effective factors in this field were identified by examining 221 articles that had obtained the necessary points. In the quantitative part, the known factors were prioritized using the Shannon entropy method. The results showed that various factors influence the volatility of stock returns, all of which can be classified into 9 dimensions and 27 components. Also, based on prioritization, macroeconomic variables, uncertainty of economic policy, global infectious diseases, geopolitical events of war and terrorism, volatility spillover, investors' sentiments, corporate governance and ownership structure are the most important factors affecting the volatility of stock returns.
