Is it safe?
One accounting flag to check: a safe balance sheet and quality strong, but an accounting pattern worth a look (common in fast growers) and big price swings.
Financially healthy, low distress risk Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.
Several accounting flags in the manipulation-likely range Beneish M-score, a forensic model that detects earnings-manipulation patterns (receivables outrunning sales, margins slipping, accrual-heavy profit).
High fundamental quality Piotroski F-score, nine pass/fail tests of year-over-year financial health across profitability, balance sheet and efficiency. 7 to 9 is strong, 0 to 3 weak.
Insiders were net sellers (-$15.7M, 90 days to Oct 22, 2026), selling is often routine.
Rock-solid balance sheet, low leverage. A rule of thumb on leverage, not a credit rating.
Large price swings, high volatility. Worst drawdown -70% · now 54% below its 52-week high.
Unless marked, from SEC EDGAR, as of Jul 3, 2026.
Against the whole market›
Percentile against every name Ryufin tracks. Higher is better; the tick marks the middle of the market. Context, not one of the checks above.
Where this answer is blind. Altman sits structurally low for utilities and pipelines; Beneish runs high for fast growers, since sales growth alone lifts it; banks and REITs are excluded.
