Maintain core GD position at Hold rating with a $390 price target over a 6-12 month horizon. Do not initiate new longs above $390; instead, widen the add-back zone to $375-385 with a defined stop below $358 to resolve undefined-risk entry flaw. Scale to full 2-3% portfolio weight only on confirmed close above $400 with volume greater than 1.5x average, and trim 10-15% on any spike to $400+ especially if LHX stalls. Q3 2026 earnings (late October) is the key validation event for EPS acceleration from $4.24 toward $4.50+.
