COHRCoherent Corp.
Is it safe?
Solid, nothing alarming: clean books and comfortable debt (AA), but big price swings.
Reported earnings show no manipulation flags Beneish M-score, a forensic model that detects earnings-manipulation patterns (receivables outrunning sales, margins slipping, accrual-heavy profit).
Mixed fundamental signals 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 (-$8.5M, 90 days to Oct 8, 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 -72% · now 27% below its 52-week high.
Unless marked, from SEC EDGAR, as of Jun 30, 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.
