MPLX LP Common (MPLX) Insider, 13F Hedge Fund & Politician Buy/Sell Thermometer

Per the Roarable RQD rating, MPLX scores 77 out of 100, a B+ grade, with the verdict "Roarable Buy — Very Good Cash & Smart-Money Inflow." The five pillars are: Fundamental Cash Engine at 14/20 (ROIC 19.3%; FCF yield 6.75%), Whale 13F Flow at 15/20 (institutional accumulation and options positioning), Insider Conviction at 18/20 (SEC Form 4 and Congressional PTR cluster flow), Macro Regime Fit at 16/20 (Beta 0.89; sector sensitivity), and Forensic Balance Sheet at 14/20 (Altman Z 2.17; Piotroski F 8/9; Debt/Equity 0.82). The strongest pillar is insider conviction, the weakest are the cash engine and balance sheet, each at 14/20. For a prospective investor, the upside case rests on cash generation and on insider and institutional activity that the rating reads as supportive. The valuation tradeoff is that the cash engine pillar is not at its maximum, and the balance sheet, while scoring a Piotroski F of 8/9, carries a Debt/Equity of 0.82 and a reported debt level that rose across the three periods shown. The rating is a data-driven summary, not a recommendation to act.
