The study looked at how different factors like earnings, past prices, and book value affect stock prices for food and beverage companies in Indonesia. They used data from 2014-2018 and found that all these factors together influence stock prices. Specifically, earnings, past prices, price to book value, and a factor called Ddown have a significant impact on stock prices. However, return on assets, book value per share, and another factor called Dup do not have a significant effect on stock prices.
