Mag 7 Dispersion

What's moving. The AI-ROI scare has torn the Mag 7 apart. Apple sits at record highs (~$316) after a ~$650B rally that Bloomberg attributes to traders fleeing the AI selloff, not to Apple's own AI progress — the Gemini-Siri arrangement repaired the narrative (CNBC). NVDA has shed ~$1T of market cap in two months from a ~$5.5T peak, trading ~$204 (-3% Monday, per IndexBox/MINING.COM). TSLA -3.3% Monday and ~-7% YTD into July 22 earnings, which Forbes flags as a likely mover with mixed recent results and BYD pressure. META soft (-1.3%); MSFT (+2.0%) and AMZN (+1.1%) firm. Caveat: our live snapshot feed failed (401), so levels are from the July 13 tape via news sources — treat intraday moves as stale.

Variant perception. The desk thinks the tape is pricing an AI demand rollover that the fundamentals contradict: TSMC's Q2 net income jumped 77% to a record, beat estimates, and the advanced-node supply/demand gap remains wide (Reuters, X commentary) — analysts expect a raised full-year revenue outlook, with capex the tell on AI demand durability.

Why now. The AAPL-long/NVDA-short rotation looks crowded and flow-driven; the signal's reversal leg argues to fade AAPL momentum and lean long NVDA against short TSLA, which carries weak fundamentals plus its own catalyst risk into 7/22. Watch TSMC's capex guide follow-through and whether Apple's bid stalls.
