⚔️ Adversarial Opposing Case: Why the MPLX Bull Thesis Could Fail

Gideon Ashmere Forensic Desk →

Even with a 76/100 (B+) score, MPLX faces multiple-compression risk if 13.1x trailing P/E re-rate toward historical sector medians or if hyperscaler/enterprise customer concentration slows in upcoming 10-Q filings.

⚠️ Forensic Kill-Switch #1

Broader market pullbacks can still drag down strong stocks in the short run.

⚠️ Forensic Kill-Switch #2

Dilution & Margin Drag: Cannibal Buyback (-2.92% YoY Shares) — any gross margin slip below 49.5% triggers an automatic RQD downgrade.

⚠️ Forensic Kill-Switch #3

Technical & Forensic Kill-Switch: A daily close below the 50D SMA ($58.40) or 200D SMA ($57.25) invalidates the momentum regime and cuts Target Base ($63.71) toward Bear Floor ($48.33).
