Data analysis techniques used descriptive statistics, classical assumption tets, multiple linier regressions, hypothesis testing and sobel test. The results of this study indicate that Debt to Equity Ratios (DER) and Earning Per Share (EPS) has no significant effects toward dividend policy, Total Assets Turnover (TATO) and firm size has significant positive effect toward dividend policy, Debt to Equity Ratio (DER), firm size, Earning Per Share (EPS) and dividend policy has significant positive effects toward stock price, while Total Assets Turnover (TATO) has no significant effects toward stock price, dividend policy is able to mediate Total Assets Turnover (TATO) and firm size toward stock price, but dividend policy is not able to mediate Debt to Equity Ratio (DER) and Earning Per Share (EPS) toward stock price.
