Abstract

The stock exchange determines the share price for the activities carried out by the seller and buyer of shares. Supply and demand influence stock prices, so they can change at any time. Changes in stock prices can be seen from the company's internal and external factors. Internal factors occur within the company, such as company performance, and can be controlled by company management. While external factors are factors that appear outside the company's control but can have an impact on company performance. This study aims to determine the effect of Net Profit Margin, Earning Per Share, Inflation, and Rupiah Exchange Rate on stock prices simultaneously and partially. The research method uses a quantitative approach. The population in this study is the Tobacco and Non-durable Household Product, as many as 15 companies.
