📌 Know What Your Company Does Before You Invest

💬 When choosing stocks to invest in, the most important thing is knowing what the company does and how it makes money. Understanding a company's business model and competitive strengths helps you make better investment decisions.

Investing without understanding the company is a major reason why people struggle to make profits. Learning about the company's industry, main products, and market position is the foundation of successful investing.

1️⃣ Terms and Background
