Is it safe?
Serious red flags: a balance sheet under strain, accounting red flags, and quality weak. Everything else is secondary until this clears.
Elevated financial-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).
Weak, deteriorating fundamentals 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 (-$415K, 90 days to Oct 22, 2026), selling is often routine.
Highly leveraged, watch solvency. A rule of thumb on leverage, not a credit rating.
Large price swings, high volatility. Worst drawdown -88% · now 49% below its 52-week high.
Unless marked, from SEC EDGAR, as of Dec 31, 2025.
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.
