The objective of this research is to investigate and analyze the change of the stocks’ performance after being split.

Sample is selected using purposive sampling. 37 companies’ stocks are selected conforming to the criteria. Using paired t-test, the data was analyzed to test whether any significant difference in performance before and after stock split.

This research found that there is a significant difference in stock performance before and after stock split. There is a significant price change before and after stock split. The trading volume before the split is also significantly different from after the split with the p-value of 0.006. Finally, in term of stock return there is a significant difference between returns 5 days before split and returns 5 days after split with the p-value of 0.024.
