Why BLDR Stock surged +2.93% Today — RQD Quant Desk Flash

Per the Roarable RQD rating, BLDR scores 60 out of 100, graded C- as "Roarable Hold — Cautious Neutral." The five pillars break down as follows: Fundamental Cash Engine 13/20 (ROIC 8.8%; FCF yield 12.58%), Whale 13F Flow 11/20 (institutional accumulation and options positioning), Insider Conviction 16/20 (SEC Form 4 and Congressional PTR cluster flow), Macro Regime Fit 8/20 (Beta 1.12; sector sensitivity), and Forensic Balance Sheet 12/20 (Altman Z 2.34; Piotroski F 6/9; Debt/Equity 0.66).

Read together, the pillars point to a mixed picture. The strongest contributors are insider-flow signals and the cash-generation metrics, while the weakest is macro regime fit, where the beta of 1.12 indicates above-market sensitivity to broader moves. The balance sheet sits in a middle zone: the Altman Z of 2.34 and Piotroski F of 6/9 are not distress signals in the source data, but they are not signs of unusual strength either. For a prospective investor, the upside case rests on the high FCF yield and insider cluster activity; the valuation tradeoff is that the stock's trailing P/E of 15.6 and forward P/E of 14.5 must be weighed against a thin 2.9% net margin and a 52-week range of $49.67 to $131.5, which shows very wide price dispersion over the period. The rating's label of "Cautious Neutral" reflects this balance rather than a directional call.

Per the SEC financials, revenue declined from $17097.3M (FY 2023) to $15190.6M (FY 2025), and net income fell from $1540.6M to $435.2M over the same span. The gross margin is 30.4%, operating margin 5.2%, and net margin 2.9%, with ROIC at 8.8%. The Altman Z-Score is 2.34 and the Piotroski F-Score is 6/9, per the Roarable RQD rating. Debt rose from $2829.0M in FY 2024 to $3098.4M in FY 2025, and the Debt/Equity ratio is 0.66.
