SUMMARY
Research on stock splits has frequently been undertaken. The results vary, but fundamentally can be classified into two groups. First, the stock split is purely "manufacturing". Second, the stock split has a real effect on stocks. The difference between these opinions raises controversy. The purpose of this study is to examine whether stock splits influence stock liquidity and return of an individual stock as well as in a group of stocks as a portfolio.Overall, the results of this study show that stock splits did influence stock price, trading volume but did not influence stock risk and abnormal return from the point of view of an individual stock as well as in a group of stocks as a portfolio. The test of a relationship stock price, trading volume and stock risk for each stock shows. On the other hand, the test of a relationship in a portfolio reveals that only stock prices significantly.
