This study investigates the impact of monetary policies on stock markets based on a sample of five open countries with growing stock market over the period 2004 to 2014. Using a random effect model for the panel regression coupled with a panel vector error correction model to study the short term and long term relationship between the variables, the findings reveal a negative relation between interest rate and stock return and a direct link between money supply and stock return. The results confirm that both in the short run and long run monetary variables explain changes in stock return.
