When: Close back above $84.70 (50 SMA) with rising volume and RSI >50

Then: Full cover position - neutralizes bearish setup

When: Confirmed close below $80.18 on volume >10M

Then: Full exit - thesis invalidation

Maintain SELL with half allocation, widen stop to $87.50, wait for confirmation (follow-through close, 200 SMA test, RSI sub-30) before considering size increase; do NOT size up into binary Q3 earnings catalyst

• Stop distance of 2.1% on $2.58 ATR with 1.32 beta is not disciplined risk management—intraday range was nearly 2 ATRs yesterday
• Opposes sizing up into binary Q3 earnings catalyst approximately 3-4 weeks away with 3.6x volume capitulation event
• 200 SMA at $80.18 is structural floor that held since autumn 2025 breakout—betting against it into binary event with larger size is concentrated gambling
• $700 million defense revenue at double-digit margins should not be dismissed as rounding error—UBS raised PT citing this as overlooked catalyst
• Q2 EPS of $1.41 vs Q1's $2.82 may reflect seasonal noise and production lumpiness, not structural deterioration—forward EPS of $15 may be aggressive but earnings normalization is plausible
• Fed on hold with 95% probability is known and priced-in; 10-year at 5% has been regime while GM rallied from mid-70s; soft oil at $95 is demand tailwind; recession probability at only 8%
• Volume capitulation events occur on 2-3% of trading days—pattern may signal exhaustion rather than continuation
• Do not size up before seeing follow-through lower close, 200 SMA test, RSI print sub-30, or Q3 earnings clarification
• Proposed stop revision to $87.50 to give position room to breathe through normal volatility

→ vs aggressive: 3:1 reward-to-risk is only true if you assume probability of bear case >50%—that assumption is doing all the heavy lifting, not the technical pattern itself

→ vs aggressive: Calling 2.1% stop 'tight and disciplined' is language written into post-mortem reports—a single earnings rumor, sector rotation, or short-covering squeeze takes you through stop before reassessment

→ vs aggressive: Sizing up into this setup is wrong impulse—betting against 200 SMA anchor in high-beta cyclical into binary event is symmetric risk in worst direction, not asymmetric reward

→ vs aggressive: $700M defense revenue at double-digit margins is strategically lazy to call rounding error—it's high-margin incremental revenue not in consensus 6 months ago; institutional re-rating models capture precisely this

→ vs aggressive: Q2 EPS vs Q1 is selection bias, not analysis—auto has documented seasonality and tariff timing that swings EPS 50% without change in underlying trajectory

→ vs aggressive: Macro tailwind argument is weaker than presented—Fed on hold is known, 10-year at 5% has been regime while GM rallied, and 8% recession probability means late-cycle grind, not cyclical collapse when defensive shorts get squeezed hardest

MAINTAIN half-allocation SHORT with tiered exit/add rules: take half off below $80.18, add to other half on failed retest of 200 SMA from below, exit fully if close above $84.70

• Technical breakdown is real with volume confirming distribution pattern
• H2 EPS math to hit $15 forward target is genuinely demanding
• Defense narrative ($700M at double-digit margins) should not be dismissed as rounding error—UBS raised target citing it, Barron's ran feature piece
• Aggressive analyst wrong to size up into binary catalyst 3-4 weeks away on 1.32 beta stock
• Conservative analyst wrong to widen stop to $87.50—pays extra premium to delay admitting trade isn't working
• Original half-allocation and $86.50 stop were correct calls that neither side should override
• First 1-3 days after Bollinger Band breach often represent best risk-reward entry, not worst
• $86.50 stop sits just above prior day's intraday high and lower Bollinger Band recovery zone—defensible
• GM is high-beta cyclical with multiple correlated cross-cutting narratives (defense re-rating, cyclical rotation, consumer credit, auto competition)
• Concentration kills on stocks with this many moving parts and binary catalyst—half allocation is justified regardless of conviction
• Asymmetry only exists if you preserve capital to deploy it

→ vs aggressive: Dismissing defense narrative as 'rounding error' is technically correct but strategically wrong—multiple independent sell-side institutions are converging on underpriced catalyst, and betting entire institutional community is wrong into a binary event is reckless rather than asymmetric

→ vs aggressive: Call to size up into binary earnings catalyst 3-4 weeks away on a 1.32 beta stock after single day's breakdown is concentrated risk, not asymmetric—5-7% move against position possible in single session on defense news or positive macro

→ vs conservative: Waiting for 'perfect' confirmation (sub-30 RSI, lower Bollinger test, 200 SMA test) means entering after price has already traveled significantly toward target—market rarely gives second-chance entries at favorable prices

→ vs conservative: Widening stop to $87.50 is ~1.85 ATRs above entry, which pays extra premium to delay admitting the trade isn't working rather than giving position 'room to breathe'
