TMUST-Mobile US, Inc.
Is it safe?
Solid, nothing alarming. Balance sheet to watch.
Mixed, watch the balance sheet Altman Z-score, a bankruptcy-risk model from five balance-sheet ratios.
Insiders were net sellers (-$138K, 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.
Moderate price swings, typical volatility. Worst drawdown -44% · now 37% 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.
