This report tracks the hyperscaler/chip/foundry basket in ai-infra.json (AMZN, NVDA, ASML, TAC, TSM, PLTR, MRVL, ARM, P, AIQ, SMH, SFTBY — 12 names), not the separate physical-buildout universe (ai-infrastructure.json). The board carries a Friday 2026-09-04 settled close. The clearest move: SFTBY's RSI jumped from 40.6 to 56.3 (+15.7) on a 7.79% single-day return, crossing the stock from just below its 200-day into a fresh strong-up trend 11.1% above it — a real trend flip, though no news coverage is on file for this basket member to confirm a cause. The basket's other big mover ran the other way: PLTR's RSI fell from 69.3 to 54.2 (-15.1), cooling sharply off last cycle's near-overbought extension.

LONG-HORIZON READ: a name whose short-window trend flag reads "down" but sits ABOVE its 200-day with a positive 1-year change is a deep pullback in an intact trend, never a breakdown. PLTR's cooldown this cycle is exactly that pattern.

Most of the basket's chip and foundry names firmed this cycle. NVDA's RSI rose from 52.3 to 60.4 (+8.1), extending an intact trend closer to its 52-week high. TSM followed with a similar move (49.6→56.8, +7.2), and ASML, MRVL, and ARM all posted mid-to-high single-digit RSI gains while staying well above their 200-day (TSM +15.0%, ASML +16.1%, MRVL +47.3%, ARM +24.9%). P — last cycle's sharpest cooldown at -20.4 RSI — recovered six-plus points (46.3→53.1) and continues to sit comfortably above its 200-day (+32.0%) with a positive year (+26.39%), the deep-pullback read from last cycle's report playing out as expected rather than deepening into a breakdown. AIQ and SMH both held roughly steady to firmer, tracking the broader chip complex.

The two outliers moved in opposite directions. SFTBY posted the basket's largest swing — a 7.79% single-day gain that pushed its RSI up 15.7 points and flipped its trend from a collapse regime just below its 200-day (-1.1%) to strong-up, now 11.1% above it. There's no news coverage on file for this name in this basket, so the move is reported without a confirmed cause. PLTR ran the other way, cooling 15.1 RSI points off last cycle's near-overbought read after a rough week (7D -6.42%, 1D -4.49%) — its cushion above the 200-day thinned from 23.1% to 15.2% and its 1-year change moderated from 17.82% to 11.65%, but both stay solidly positive, so this reads as a deep pullback rather than a trend break. PLTR's news on file predates this move (last pulled 2026-08-08, covering the early-August earnings beat), so the specific catalyst behind this week's pullback isn't confirmed either way. TAC remains the one name in this basket where the long-horizon check shows real weakness rather than a horizon-mismatch trap — it trades 8.8% below its 200-day with a flat-to-negative year (-1.32%), even as its RSI held roughly steady (41.8→40.8) at the low end of the basket.

1. SFTBY posted the basket's sharpest move and a real trend flip: RSI 40.6→56.3 (+15.7), crossed from -1.1% below its 200-day to +11.1% above it — no sourced cause on file.
2. PLTR cooled the hardest: RSI 69.3→54.2 (-15.1), 200-day cushion 23.1%→15.2%, 1-year change 17.82%→11.65% — a deep pullback, not a breakdown, but the specific driver isn't confirmed in the news on file.
3. NVDA firmed sharply: RSI 52.3→60.4 (+8.1), closing in on its 52-week high.
4. TSM firmed: RSI 49.6→56.8 (+7.2), still 15.0% above its 200-day.
5. ARM recovered off the oversold edge: RSI 40.0→48.0 (+8.0), still 24.9% above its 200-day.
6. P continued recovering from last cycle's sharp cooldown: RSI 46.3→53.1 (+6.8), still 32.0% above its 200-day with a positive year.
7. SMH firmed: RSI 45.0→51.2 (+6.2), tracking the broader semis complex.
8. ASML firmed: RSI 43.4→48.3 (+4.9), still 16.1% above its 200-day.
9. MRVL firmed on a sharp single-day pop: RSI 47.2→51.1 (+3.9), 1D +7.05%, still the basket's best 1-year gain (+248.75%).
10. AMZN cooled: RSI 55.9→49.5 (-6.4), margin above its 200-day thinning to +8.1%.
11. TAC held roughly steady at the basket's low end: RSI 41.8→40.8 (-1.0), still the one name with real long-horizon weakness.
12. AIQ held roughly steady: RSI 57.3→56.9 (-0.4).

RSI < 25 = capitulation. RSI 25-40 = oversold (check trend, death-cross, and the long-horizon numbers before treating as a buy). RSI 40-70 = neutral-to-healthy. RSI > 70 = extended. "1Y%" and "vs SMA200" are the long-horizon check: a name below its 200-day with a weak or negative year is real weakness; a name above its 200-day with a strong year is a deep pullback even when its short-window RSI looks weak.

None.

None this cycle — TAC (40.8) sits at the basket's low end but is the only name below 45.

All 12 names: NVDA (60.4), TSM (56.8), AIQ (56.9), SFTBY (56.3), PLTR (54.2), P (53.1), MRVL (51.1), SMH (51.2), AMZN (49.5), ASML (48.3), ARM (48.0), TAC (40.8).

• Whether SFTBY's trend flip (RSI +15.7, crossed above its 200-day) holds or reverts, given no sourced catalyst is on file to explain it.
• Whether PLTR's sharp cooldown (RSI -15.1) stabilizes above its 200-day or the pullback deepens further, given the news on file predates this week's move.
• Whether P's continued recovery from last cycle's sharp drop extends into a clean re-acceleration or stalls.
• Whether TAC's continued below-200-day, flat-to-negative-year profile deepens into a real breakdown or finds a floor.
• Whether the broad chip/foundry firming (NVDA, TSM, ASML, MRVL, ARM) extends into the next cycle or was a one-week bounce.
