FSIStabilità finanziaria

Financial-stability composite for {legal_name} blending Altman Z-Score, Piotroski F-Score, and operating-margin volatility. EXTRACTION RULES: Return composite_signal with one sub-signal per dimension — (a) altman_z_score (named, value 0-100 mapped from raw Z: Z<1.8→25, 1.8-2.99→55, 3+→85; cite SEC 10-K + StockAnalysis), (b) piotroski_f_score (value 0-100 mapped from raw 0-9: 0-3→20, 4-6→55, 7-9→90), (c) margin_volatility (value 0-100 inverse of coefficient of variation across 8 quarters: CV<5%→90, 5-15%→65, 15-30%→40, 30+→20). Each sub-signal MUST carry source_url backing it (SEC 10-K / 10-Q PDF, Macrotrends, StockAnalysis, Gurufocus). If the company files no public balance sheet / income statement (private, no filing) and no reputable third-party computes these figures, return type="absent" reason="not_disclosed" — NEVER estimate or fabricate an Altman/Piotroski/volatility value. Server applies composite_signal_score — DO NOT compute any 0-100 score.
