Valuation

very high

P/E Price-to-earnings ratio: how many years of profit does the stock cost? The lower, the cheaper the valuation. No earnings means no P/E.

123.5

Forward P/E P/E based on expected earnings for the next 12 months instead of past earnings — analysts' bet on the future.

55.9

PEG P/E divided by expected earnings growth: puts valuation in relation to growth. Around 1 is considered fair, well above that is pricey.

0.8

P/B Price-to-book ratio: market value relative to book equity.

18.3

P/S Price-to-sales ratio: market value divided by annual sales. Important for companies that aren't (yet) profitable.

9.6

EV/EBITDA Enterprise value including debt (EV) relative to operating profit before depreciation and amortization (EBITDA) — more comparable than P/E because debt counts too. Extreme values arise when EBITDA is near zero.

90.2

Price/FCF Market value divided by free cash flow: how many years of freely available cash does the stock cost? More honest than P/E because cash flow is harder to dress up.

64.2

Profitability

Gross Margin Gross margin: what's left of sales after only direct production costs are deducted — the product's pricing power.

43.1%

EBIT Margin EBIT margin: operating profit as a percentage of sales — the earning power of the core business before interest and taxes.

15.2%

Net Margin Net margin: what's left of sales as profit after ALL costs, interest, and taxes.

7.9%

Return on Equity Return on equity: how much profit does the company generate per year on shareholders' equity?

15.5%

Return on Assets Return on assets: how much profit the company generates from its total assets (equity and debt combined).

6.7%

Balance Sheet & Safety

Equity Ratio Equity ratio: equity as a share of total assets. The higher, the more resilient the balance sheet.

47.9%

Debt/Equity Leverage ratio: financial debt divided by equity. Under 1 is generally seen as solid; negative values mean negative equity.

0.7

Altman Z″ Edward Altman's bankruptcy early-warning score. We use the Z″ variant, built from four balance-sheet ratios — it is designed for service companies and non-manufacturers and uses book value instead of market value. On that scale: below 1.1 = danger zone, 2.6 and up = safe zone, in between a grey area. Because the classic Altman Z is calculated differently, the two numbers are not directly comparable. The formula does not fit banks, insurers, or real-estate stocks.

Piotroski Balance-sheet health check by Joseph Piotroski: 9 yes/no criteria on profit, cash flow, leverage, and efficiency. 7+ is very solid, under 3 is a red flag.
