This report tracks the 9-name hyperscaler/chip/foundry basket (ai-infra.json — AMZN, NVDA, ASML, TAC, TSM, PLTR, MRVL, ARM, P), unchanged from the 2026-07-17 edition, not the separate 52-name physical-buildout universe (ai-infrastructure.json). Because the prior edition already used this same 9-name basket, the comparisons below are a valid direct read against 2026-07-17. The clearest move: AMZN reversed from the steadiest name in the basket to a genuine decliner (RSI 51.4→37.2), while MRVL and ARM — the two clearest breakdowns two weeks ago — both stabilized meaningfully off their craters.

FROTH READ: vs VWAP measures distance from the average buyer's cost basis across the instrument's full history.

AMZN is the reversal story of this basket. Two weeks ago it was the steadiest name in the group; now its RSI has fallen from 51.4 to 37.2, its 7-day change flipped from +0.77% to -6.12%, its 30-day change flipped from +1.16% to -0.92%, and its gap to its 52-week high widened from -11.25% to -16.12%.

MRVL and ARM, the two clearest breakdowns two weeks ago, both stabilized meaningfully off their craters. MRVL's 30-day drawdown eased from -39.23% to -29.79% (RSI 35.7→39.0) and ARM's from -39.2% to -27.59% (RSI 38.4→38.0) — still deeply damaged names, but no longer accelerating lower.

TSM cooled into a shallower drawdown (RSI 39.4→42.3, 30D -13.8%→-8.49%), TAC's slide reversed outright (RSI 42.7→49.7, trend flipped strong-down→up), and ASML and NVDA both ticked higher on RSI while shrinking their 52-week gaps. P (Everpure, formerly Pure Storage), which had no comparable prior read last cycle, improved on both RSI and week (42.8→50.3, 7D -12.54%→+7.47%).

PLTR is the one mixed case in the basket. Its RSI fell from 52.9 to 41.9 and the most recent week reversed hard (7D +4.41%→-7.15%), even though the trailing 30-day figure stayed net positive (+3.04%→+8.3%, reflecting gains earlier in the window that haven't yet rolled off) — it remains death-crossed and well below VWAP either way.

This is a valid direct ticker-for-ticker comparison — the 07-17 edition of this scan already used the same 9-name basket.

1. AMZN reversed from steadiest to weakest: RSI 51.4→37.2, 7D +0.77%→-6.12%, 30D +1.16%→-0.92%, 52wkHi gap -11.25%→-16.12%.
2. MRVL stabilized off its crater: RSI 35.7→39.0, 30D -39.23%→-29.79%, 52wkHi gap -42.8%→-36.55%.
3. ARM stabilized in tandem: RSI 38.4→38.0, 30D -39.2%→-27.59%, 52wkHi gap -40.98%→-37.48%.
4. TSM cooled into a shallower drawdown: RSI 39.4→42.3, 30D -13.8%→-8.49%, 52wkHi gap -16.83%→-13.24%.
5. TAC's slide reversed: RSI 42.7→49.7, 7D -6.75%→+3.47%, trend flipped strong-down→up.
6. NVDA improved: RSI 48.1→51.0, 7D -3.86%→+1.99%, 30D -3.74%→+3.94%.
7. ASML ticked higher: RSI 47.9→48.3, 30D -9.44%→-0.32%.
8. PLTR weakened on the week despite a still-positive trailing month: RSI 52.9→41.9, 7D +4.41%→-7.15%, 30D +3.04%→+8.3%.
9. P improved on both measures: RSI 42.8→50.3, 7D -12.54%→+7.47%, 30D -7.01%→+2.42%.

RSI < 30 = capitulation zone (check trend/death-cross before treating as a buy). RSI 30-40 = oversold, often still structurally weak in this group. RSI 40-70 = neutral-to-healthy. RSI > 70 = extended. "vs VWAP" measures distance from the average buyer's cost basis — the further above 0%, the more "paid up" the current price relative to its own trading history.

None.

AMZN (37.2), ARM (38.0), MRVL (39.0). All three still carry real structural damage — AMZN newly so, MRVL/ARM easing off their craters but not resolved.

PLTR (41.9), TSM (42.3), ASML (48.3), P (50.3), NVDA (51.0), TAC (49.7).

• Whether AMZN's reversal from steadiest to weakest is a one-week wobble or a genuine change in the name's relative strength within this basket.
• Whether MRVL/ARM's stabilization (30-day drawdowns easing from roughly -39% to roughly -28-30%) continues toward a real bottom.
• Whether PLTR's weak week is the start of unwinding its month-long gain or just noise.
• Whether the ai-infrastructure scan slot stays on this 9-name basket going forward (unchanged for two cycles now) or reverts to the 52-name physical-buildout universe.
