Why It Matters

EPS indicates the profit attributable to each outstanding share.

Why It Matters

• Widely used in company analysis.
• Supports valuation through the P/E Ratio.
• Helps compare earnings performance over time.

10. Free Cash Flow (FCF)

Best Practices When Using Financial Ratios

• Compare companies within the same industry.

Conclusion

Understanding financial ratios is an important step toward making informed investment decisions. Metrics such as the P/E Ratio, P/B Ratio, ROE, Debt-to-Equity Ratio, and Operating Margin provide valuable insights into a company's valuation, profitability, efficiency, and financial health.
