Maintain GM at ~$87.58 with HOLD rating as the valuation cushion (Forward P/E 5.95x, PEG 0.35, TTM FCF $21.93B, $8B debt reduction, $6.3B annualized buybacks) is offset by deteriorating momentum (MACD histogram -78% in 9 sessions, three failed retests of $91.85, Q1→Q2 sequential net income decline of 50%, $1.5B inventory build). Stop refined to ~$84.50, with trim rule added if 50 SMA at $81.35 fails on rising volume.
