Capital markets play an important role in the global economy, with total market capitalization in 2019 in the tens of trillions of dollars. Many factors, both internal and external, affect a company’s stock price. This aim of this study is to investigate whether financial factors can be good indicators to aid investors in their investment decision-making process. In the study, we focus on the internal financial reporting factors that affect company stock prices using the three personal computer companies with the largest market shares (Hewlett-Packard, Lenovo, and Dell). As information from financial reports can be used to assess a company’s financial condition, we explore whether certain financial metrics (gross margin, ROE, ROA, EPS, and the debt-to-equity ratio) can be good indicators of a company’s stock price. We analyze the data using regression analysis and also conduct a practical test of the three companies’ stock prices to prove our argument. For our sample, we find that certain profitability measures are good indicators of stock prices. The findings of this study can help investors, companies, and future researchers formulate strategies to further reduce investment risk.
