This study examines the impact of macroeconomic variables on the stock price index of the Egyptian stock exchange EGX30 by analyzing quarterly data from January 2015 to December 2022. To give better results through the use of data published by the Central Bank of Egypt on those variables, the independent variables consisted of (Exchange rate, GDP, inflation rate) while EGX30 represented the dependent variable, and since all variables are fixed at the first difference, the ARDL model is therefore applied to verify the short-term and long-term common integration of the study variables using E views 10. The study followed the analytical descriptive approach, and the economic measurement method, and the results indicate that stock prices on the stock exchange in the long term are significantly affected when the exchange rate rises in the short term, inflation is among the most influential variables on the price index. While other variables are not as important to equity prices, the central bank should be vigilant during high inflation rates because this hurts investment and the stock market.
