The results showed a significant difference to the average trading volume, but there was no significant difference to the average stock return before and after the stock split policy. The test results of the average difference between blue chip and non blue-chip companies have no significant differences. The company's market capitalization has no significant effect on stock returns and trading volume in the stock split period. The results of this study can be used as reference material for investors and companies in making decisions.
