Key Financial Ratios
1. Profitability Ratios
ROE (Return on Equity):
ROE = Net Income / Shareholders' Equity × 100%
- Good level: >15% (depends on sector)
- Interpretation: How efficiently management uses shareholder capital
ROA (Return on Assets):
ROA = Net Income / Total Assets × 100%
- Good level: >5-8%
- Interpretation: Productivity of all company assets
Net Profit Margin:
Net Margin = Net Income / Revenue × 100%
- High margin: >10% (premium brands)
- Average margin: 3-7% (mass market)
2. Valuation Ratios
P/E (Price to Earnings):
P/E = Stock Price / Earnings Per Share
- P/E < 10: Potentially undervalued
- P/E 10-20: Fair valuation
- P/E > 25: Expensive or growth company
P/B (Price to Book Value):
P/B = Stock Price / Book Value Per Share
- P/B < 1: Stock trading below book value
- P/B 1-2: Reasonable valuation
- P/B > 3: High growth expectations
PEG (P/E to Growth):
PEG = P/E / Expected Earnings Growth (%)
- PEG < 1: Attractive valuation relative to growth
- PEG = 1: Fair price
- PEG > 1.5: Overpriced relative to growth
3. Liquidity Ratios
Current Ratio:
Current Ratio = Current Assets / Current Liabilities
- Safe level: 1.5-2.0
- < 1.0: Liquidity problems
- > 3.0: Inefficient capital use
Quick Ratio (Acid Test):
Quick Ratio = (Current Assets - Inventory) / Current Liabilities
- Safe level: >1.0
- Interpretation: Liquidity without selling inventory
