Financial Ratios Explained
The essential toolkit for analyzing any listed company
Why Financial Ratios Matter
Financial ratios distill complex financial statements into comparable, meaningful numbers. They allow investors to quickly assess a company's profitability, efficiency, leverage, and valuation relative to peers.
No single ratio tells the complete story. Smart investors use a combination of ratios across categories to build a comprehensive picture of a company's financial health.
Valuation Ratios
Price-to-Earnings (P/E) Ratio: Share price divided by earnings per share. A P/E of 15 means you're paying $15 for every $1 of earnings. Lower P/E can indicate undervaluation, but context matters — cyclical companies may have misleadingly low P/Es at peak earnings.
Price-to-Book (P/B) Ratio: Share price divided by book value per share. Useful for asset-heavy industries like banking and real estate. A P/B below 1.0 suggests the stock trades below the accounting value of its assets.
EV/EBITDA: Enterprise value divided by EBITDA. This ratio is capital-structure neutral, making it ideal for comparing companies with different debt levels.
Profitability Ratios
Return on Equity (ROE): Net income divided by shareholders' equity. Measures how effectively management deploys shareholder capital. Consistently high ROE (above 15%) often signals a competitive moat.
Net Profit Margin: Net income divided by revenue. Shows how much of each dollar of revenue becomes profit. Compare within industries — a 5% margin is excellent for grocery retailers but poor for software companies.
Return on Invested Capital (ROIC): Measures returns generated on all invested capital (debt + equity). Warren Buffett considers this the single most important metric for evaluating business quality.
Leverage Ratios
Debt-to-Equity (D/E): Total debt divided by total equity. Higher ratios indicate more leverage. What's acceptable varies by industry — utilities often operate with high D/E, while technology companies typically carry little debt.
Interest Coverage: EBIT divided by interest expense. Shows how comfortably a company can service its debt. Below 2x is concerning; above 5x suggests conservative leverage.
Net Debt/EBITDA: Indicates how many years it would take to pay off debt using current cash flow. Below 2x is generally comfortable; above 4x raises red flags.
Applying Ratios to Egyptian Stocks
When analyzing stocks on the Egyptian Exchange (EGX), adjust your ratio expectations for the local context. Egyptian banks typically trade at lower P/B ratios than global peers due to country risk premiums. Industrial companies may show volatile margins due to currency fluctuations.
Always compare ratios within the same market and sector. A P/E of 8x on the EGX may represent fair value, while the same ratio on the S&P 500 would signal deep value.
FAQ
What is a good P/E ratio?
There's no universal 'good' P/E ratio. It depends on the industry, growth rate, and market conditions. Generally, a P/E below 15 is considered value territory, while above 25 may indicate growth expectations. Always compare P/E ratios within the same sector.
Which financial ratio is most important?
No single ratio is most important. For value investors, P/E and P/B are key starting points. For assessing business quality, ROE and ROIC are critical. For risk assessment, debt-to-equity and interest coverage matter most. Use them in combination.
How do I calculate intrinsic value?
The most common method is a Discounted Cash Flow (DCF) analysis, which projects future free cash flows and discounts them to present value. Simpler approaches include using a normalized P/E multiple or asset-based valuation for companies with significant tangible assets.
