When: Confirmed close above $601.77 on volume >5M shares with RSI expansion (not plateau); trailing stop at $595

Then: Deploy 2-3% portfolio

When: Q3 2026 earnings (late October) delivering ≥13% revenue growth AND ≥17% EPS growth AND raised full-year guidance; stop below post-earnings low

Then: Deploy 2-3% portfolio

HOLD - Refuse to deploy capital at 575; wait for 520-540 entry with 515 stop-loss on any new positions

• 31.65x earnings multiple provides no margin of safety, instead representing 'margin of danger' given the fully priced assumption of uninterrupted growth
• 8% Polymarket recession probability represents a tail risk that could crush a 31x multiple stock in a bad scenario
• RSI at 69.46 is functionally at the overbought threshold (above 70 is definitionally overbought) and represents elevated mean reversion risk
• MACD histogram compression from 5.39 to 1.23 indicates waning upside momentum, historically preceding consolidation pullback or volatility expansion
• Declining volume on new high most parsimoniously indicates the rally is running out of buyers, not institutional accumulation
• Circle Arc September 16 mainnet launch represents option value only, not near-term revenue, with uncertain upside and real downside if launch underwhelms
• MA has already rallied from 464 to 575 in two months, meaning the market has substantially priced in the stablecoin narrative
• A disciplined investor waiting at 520-540 retains 100% of capital to deploy at a better entry with superior risk profile
• Margin of safety means buying below intrinsic value; paying full price for an asset means bearing all downside if reality disappoints
• Capital preservation is not for markets that go straight up but for markets that don't, and those arrive without warning

→ vs aggressive: The 'great company justifies 31.65x multiple' argument ignores the graveyard of wonderful companies bought at terrible prices (Cisco at 100x earnings); great business at ridiculous multiple is a great short

→ vs aggressive: RSI at 69.46 is not 'strong, not exhausted'—it is functionally at the overbought line; MACD compression from 5.39 to 1.23 is waning momentum, not consolidation into a higher base

→ vs aggressive: Institutional accumulation thesis is speculative interpretation layered on ambiguous data; conservative interpretation of declining volume on new high is 'rally running out of buyers'

→ vs aggressive: The 'sit in cash is expensive' argument is dangerous and mirrors 'this time is different' mentality; missing a 30% run is not worse than catching a 25% drawdown

→ vs aggressive: Circle Arc is option value only, not near-term revenue; chasing a binary catalyst at top-decile multiple with no visibility into actual outcome is imprudent risk management

→ vs aggressive: The 10% drawdown cost of waiting ignores the larger and harder-to-recover cost of being wrong on a chase at elevated multiple; if MA pulls to 520, buyers at 575 face 9.5% loss with extended downside below 519

HOLD existing positions with trailing stop under $565; deploy 1-2% starter position at current levels; wait for $520-$540 pullback or $601 breakout on volume above 3M for larger tranche

• Forward P/E of 25x is reasonable; trailing P/E of 31.65x requires belief next 12 months match recent past
• Multiple compression is asymmetric: stock at 31x can compress to 25x or 23x (20-25% haircut) versus 10% at 20x
• MACD histogram compression from 5.39 to 1.23 with MACD line still positive is ambiguous, not confirmation of trend continuation
• RSI at 69.46 is right at the overbought threshold but not technically over it
• Declining volume on new high is ambiguous: institutional accumulation OR rally exhaustion, neither provable
• Circle Arc has option value but MA has already rallied from $464 to $575 over two months, partially pricing in the narrative
• BlackRock validating Mastercard's infrastructure alongside Visa with $15.3 trillion AUM is structurally meaningful
• Technical report recommended hold with trailing stop under $565, not a sell signal
• Starter position (1-2%) gives catalyst exposure without forcing full concentration at technically extended levels
• Opportunity cost of waiting is bounded (miss 10-15% upside at worst); opportunity cost of chasing is unbounded if indicators are right
• September 16 Arc mainnet launch is a forced decision point regardless of position
• Macro supports patient accumulation: 88% probability of zero Fed cuts in 2026, firm dollar supports international translation

→ vs aggressive: Trailing P/E of 31.65x is not functionally equivalent to any multiple; it compresses faster than lower multiples when forward indicators wobble

→ vs aggressive: MACD reading contradicts the technical analyst who wrote the report; 'consolidation into higher base' is not what the report says

→ vs aggressive: Full-size new position (2-3%) at $575 with these indicators is unjustifiable

→ vs aggressive: Cost of waiting is treated as free when it's bounded (miss 10-15% upside) while cost of chasing is unbounded (full downside if pullback occurs)

→ vs conservative: Zero new capital is too extreme; quality compounder deserves minimum exposure for catalyst and name relationship

→ vs conservative: RSI at 69.46 is at the line but not over it; 'screaming exit' framing doesn't match indicator reality

→ vs conservative: Pullback to $520-$540 may not materialize; a 14% grower with confirmed uptrend and known catalyst can grind higher without offering pullback

→ vs conservative: If MA goes straight to $610 without visiting $540, Conservative plan misses entire move—real cost they don't account for
