214Mio.

Float Share of stock freely tradable on the market — not locked up in the hands of founders, insiders, or major shareholders.

98.8%

Beta Volatility versus the overall market: 1 = moves like the market, 2 = twice as much, under 1 = calmer than the market.

0.7

Performance

2.90%

Perf. 3M Price performance over the last 3 months.

4.70%

Perf. 6M Price performance over the last 6 months.

-7.70%

-8.70%

-17.1%

Valuation

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.

20.6

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

18.8

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

3.0

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

7.8

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

4.4

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.

13.4

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.

23.7

Profitability

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

47.3%

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

35.8%

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

22.5%

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

46.5%

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

6.1%

Balance Sheet & Safety

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

19.1%

negative equity

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

-2.5

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.

Payout Ratio Share of profit paid out as dividends. Over 100% means the company is paying out more than it earns — not sustainable long-term.

17.1%

22Years

Increase Streak How many years in a row the dividend has been raised — the gold standard for dividend payers.
