It is important for both the monetary policy makers and investors to understand the impact of monetary policy shocks to real asset prices. This paper used the event-study method to test the intraday effects of monetary policy shocks on Australian stock market return in different dimension. The results show that a 25-basis-point rate cut target surprise is associated with 0.62% to 0.7% increase to the whole Australian stock market index. The results of industry indexes show that the industry indexes react differently to monetary policy shocks and path surprise is never significant in all event windows. This paper also tested the speed of stock market reacting to monetary policy shocks. The results suggest that all stock market indexes stop reacting to monetary policy shock after 90 to 120 minutes the monetary policy decision is announced. Lastly, the study of individual stocks shows that the size and market to book ratio factors do not affect magnitude of individual stock reaction to monetary policy shock.
