The study looked at how trading volume and stock return are related in the Malaysian stock market during different economic shocks. They found that there is a significant bidirectional relationship between trading volume and stock return. This means that when trading volume goes up, stock returns also tend to increase. The positive relationship between trading volume and stock return was consistent before and after economic shocks, except during the global financial crisis and the 14th Malaysian general election. Overall, investors tend to invest in stocks when they see an increase in trading volume, leading to higher stock returns.
