Gross profit margin is a financial metric that measures the profitability of a company’s core business operations by analyzing the proportion of revenue that exceeds the cost of goods sold (COGS) or cost of revenue. It is a significant metric in stock analysis as it provides insights into a company’s ability to generate profit from its core business operations. It helps investors and analysts understand how efficiently a company manages its production costs and pricing strategies.

In this article, we are going to use Python to perform fundamental analysis of a target stock by evaluating its gross profit margin.
