MBXMBX Biosciences, Inc.
Is it safe?
Caution warranted: heavy debt (CCC) and big price swings.
Insiders were net sellers (-$24K, 90 days to Oct 22, 2026), selling is often routine.
Debt against weak or negative operating profit. A rule of thumb on leverage, not a credit rating.
Large price swings, high volatility. Worst drawdown -78% · now 31% below its 52-week high.
Against the whole market›

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.
