Profitability
Gross marginVery weak
Among the 10% lowest rated companies in the industry
The gross result as a share of revenue — how much of the revenue is left after variable costs to cover the company's fixed costs.
Operating marginStrong
Among the 40% highest rated companies in the industry
EBIT as a share of revenue — the share of revenue remaining as earnings once all operating costs are covered. A key measure of earning power.
Net profit marginWeak
Among the 30% lowest rated companies in the industry
The profit for the year as a share of revenue — the company's ability to turn revenue into profit.
Return on equity (ROE)Average
Around the average of companies in the same industry
Net profit as a percentage of equity — the return the owners earned on their invested capital this year.
Return on assets (ROA)Weak
Among the 40% lowest rated companies in the industry
Net profit as a percentage of total assets — the return generated on the capital employed.
Return on net assets (RONA)Weak
Among the 40% lowest rated companies in the industry
Profit relative to net assets (total assets minus total debt) — the ability to generate earnings from the net asset base alone.
Basic earning power (BEP)Strong
Among the 30% highest rated companies in the industry
EBIT relative to total assets — the company's earning power before the effects of tax and financial leverage.
Capacity ratioVery strong
Among the 10% highest rated companies in the industry
Shows how strongly fixed costs weigh on the gross result — a high ratio means fixed costs take only a small bite out of the earnings from basic operations.
Liquidity
Current ratioVery weak
Among the 10% lowest rated companies in the industry
Current assets relative to short-term debt — the ability to settle short-term obligations with current assets alone. Around 150% is considered satisfactory from a credit perspective.
Quick ratioVery weak
Among the 20% lowest rated companies in the industry
Current assets excluding inventory relative to short-term debt — whether the most liquid assets alone can cover the short-term obligations. A value of 1 or above signals a healthy liquidity position.
Cash ratioWeak
Among the 30% lowest rated companies in the industry

Current assets to equityVery weak
Among the 10% lowest rated companies in the industry
Current assets relative to equity — an indicator of the balance-sheet structure and of the company's short- and long-term financing. The healthy level is highly industry-dependent.
Fixed assets to long-term capitalVery weak
Among the 10% lowest rated companies in the industry
Fixed assets relative to long-term capital (equity plus long-term liabilities). Below 100% means the long-term capital finances more than just the fixed assets — a healthier liquidity position.

Cash flow relative to profit — the ability to convert reported profits into accessible cash.

Total debt relative to the balance-sheet total — the share of the assets financed by debt rather than equity.
Debt to equityVery weak
Among the 10% lowest rated companies in the industry
Debt relative to equity — the company's leverage. A higher value means heavier reliance on debt financing.
Liabilities to equityVery weak
Among the 10% lowest rated companies in the industry

Income to debtWeak
Among the 40% lowest rated companies in the industry
