Reason: NVDA cooled from last read's resolved-fragility strength (RSI 57 to 48) but stays thesis-intact and the steadiest large-cap read alongside AMZN; MRVL and ARM are now the ai-scan's own flagged "standout deterioration," both down ~39% over 30 days; PLTR bounced off its lows but remains below VWAP and death-crossed.

Tape Read

This basket cooled hard from two reads ago's turnaround story. NVDA's RSI eased back to 48.1 from 57.2 (-3.86% 7D, -3.74% 30D), still weak-down but the ai-scan tags it "🟡 Cooled but thesis flagged intact" — the SMA20 cushion narrowed to just +0.3% after briefly running hot. AMZN is once again the steadiest name in the group: RSI 51.4 (essentially flat from 51.0), +0.77% 7D, thesis intact — the same scan explicitly calls it "📈 Accumulate — steadiest, thesis intact." TSM cooled further into oversold-adjacent territory (RSI 49.8→39.4, -8.23% 7D, -13.8% 30D), now -8.9% below its SMA20. MRVL and ARM are the real story: both are now flagged "standout deterioration" by the ai-scan itself, down -39.23% and -39.2% respectively over 30 days even as they remain 23-32% above VWAP — a genuine breakdown, not just de-extension. PLTR bounced (RSI 48.4→52.9, +4.41% 7D) but stays strong-down/death-crossed and -16.23% below VWAP; the ai-scan calls it "❌ Avoid — bounced, still below VWAP."

• NVDA — WATCH (downgraded from PROMOTE): RSI 48.1 (down from 57.2), weak-down, thesis flagged intact, SMA20 cushion narrowed to just 0.3 points — cooling off last read's strength, not breaking down.
• AMZN — PROMOTE: RSI 51.4, weak-down/basing, +0.77% 7D, thesis intact — steadiest name in the group again, unchanged read.
• TSM — PASS (downgraded from WATCH): RSI 39.4 (down from 49.8), -8.9% below SMA20, -13.8% 30D — cooled into oversold-adjacent, no longer the soundest compounder call.
• MRVL / ARM — PASS: down -39.23% and -39.2% over 30 days — flagged "standout deterioration" by the engine itself; still rich vs VWAP (+23.6%/+32.0%) but the chart has genuinely broken, not just cooled.
• PLTR — PASS: RSI 52.9 (up from 48.4), strong-down/death cross, 16.23 points below VWAP — a bounce inside a broken structure, still the clear avoid.

Lead pick: AMZN — the only name in the basket with an unchanged, steady, thesis-intact read this cycle; NVDA is the name to watch for whether this week's cooldown holds or extends. MRVL/ARM are this week's downgrade: last read's "de-extending but rich" call is now an outright breakdown.
