Every name in this cut except one lost RSI ground this week — the cohort's cleanest single-scan cooldown in months, with $GEV and $TLN (last scan's only two confirmed uptrends) both dropping 15 points. Read on the week alone this looks like a rollover, but the long-trend check tells a different story: most of this cut is still trading well above its 200-day average with triple-digit one-year returns ($MRVL +233%, $INTC +283%, $AMD +189%, $MXL +340%) — this is a deep, broad pullback inside intact multi-year uptrends, not a breakdown. The real weak spots — $CEG, $TLN, $QCOM, and $SWKS — are the four names actually trading below (or flat on) their own year-ago price with a negative long-trend alpha, and that is where the caution belongs.

Data as-of the 2026-08-21 close (Friday's settled session) — every name in this cut carries a fresh bar this scan.

Source: semis.json + ai-infra.json + energy.json, deduped to the core NVDA-adjacent chip/AI-infra/power-demand names — same 20-ticker cut and exclusion methodology as the prior scan (AMZN/PLTR/TAC/P/AIQ/SMH excluded from ai-infra.json; EOSE/NEE/FSLR/ENPH/TAC/XLE/XOP/CMBT excluded from energy.json; SMH/SOXX excluded from semis.json as broad-basket duplicates). Prior scan: 2026-08-14-nvda-ecosystem.

This scan's dominant story is breadth, not any single name: 19 of the 20 tracked tickers lost RSI ground this week, with $MXL the sharpest single mover (RSI down 12.3 points on a 21.4% weekly decline) and $GEV and $TLN — the cut's only two confirmed uptrends from the prior scan — both dropping 15 points apiece. On a pure week-over-week read, that looks like the group is rolling over together.

The long-trend check changes the picture. Most of this cohort is still trading well above its 200-day average with a strongly positive year-over-year return: $MRVL is 63% above its 200-day and up 233% over the past year; $AMD is 44% above and up 189%; $INTC is 26% above and up 283%; $MXL — despite this scan's worst single-name drop — is still 48% above its 200-day and up 340% over the year. That combination is a deep pullback inside an intact multi-year uptrend, not a structural breakdown, and it applies to the majority of names in this cut, including $NVDA itself (10% above its 200-day, up 23% over the year, thesis still marked intact).

Four names fail that test and deserve the "genuinely weak" label instead: $TLN and $CEG are both below their 200-day average with a negative year-over-year return (TLN -12.1%, CEG -12.7%) and a negative long-trend alpha (both badly lagging the broader tape over one and three years). $QCOM is likewise below its 200-day with a barely-positive year (+4.3%) and a badly negative alpha — the underlying data tags its regime "collapse." $SWKS is the trickiest case: it sits just above its 200-day (+5.0%) but is down 9.9% over the past year with a heavily negative alpha — flat-or-down on the year with lagging alpha is the tell for a name that's actually broken, even though this week's RSI (52.1) looks unremarkable next to the rest of the cut.

$AVGO and $ON sit right on the line: both are marginally below their 200-day averages (-0.2% and -3.7% respectively) but both are still up solidly over the past year (+28% and +52%) with positive alpha — read these as testing the 200-day rather than confirmed breakdowns, worth a close watch but not yet in the same bucket as $TLN/$CEG/$QCOM/$SWKS.

• 19 of 20 names lost RSI ground this scan — the broadest single-scan cooldown this cut has shown; only $MRVL gained (54.0 → 55.8).
• $GEV and $TLN — the prior scan's only two confirmed uptrends — both dropped roughly 15 points. GEV: 56.4 → 41.0 (-15.4), price $1,063.25 → $956.85 (-10.0%). TLN: 52.6 → 37.3 (-15.3), price $362.74 → $314.46 (-13.3%).
• $MXL posted the cut's single sharpest weekly move. Price fell 21.4% for the week, RSI 56.1 → 43.8 (-12.3) — still 48% above its 200-day and up 340% on the year.
• $ON became the cut's weakest print. RSI 44.7 → 35.5 (-9.2), now testing its 200-day average from below.
• $AVGO cooled sharply and slipped below its 200-day. RSI 46.5 → 38.7 (-7.8), vs-200-day moved from positive to -0.2%.
• $NVDA and $CEG both cooled roughly 10-11 points. NVDA: 62.8 → 51.0 (-11.8). CEG: 63.2 → 53.0 (-10.2) — CEG remains the cut's highest RSI print regardless.
• $ASML gave back last scan's upgrade. RSI 59.8 → 50.5 (-9.3) — no longer extended, still up 140% over the year.
• $MRVL was the only name to gain ground. RSI 54.0 → 55.8 (+1.8), price up 6.8% for the week.
• No stale bars this scan — every name carries a fresh 2026-08-21 close.
• Universe unchanged. Same 20 tickers and exclusion methodology as the prior scan.

RSI measures how stretched a stock is over the past 14 sessions — under 30 signals oversold, over 70 signals overbought. vs SMA20 is the price gap to the 20-day average; a fast decline shows up as a large negative number. 1Y% and vs SMA200 are the two numbers to check before calling anything a breakdown: a name trading above its 200-day average with a strongly positive year is in a deep pullback inside an intact trend no matter how ugly the week looks — most of this cut fits that description. A name trading below its 200-day with a flat-to-negative year and negative long-trend alpha, like $TLN, $CEG, $QCOM, and $SWKS, is the one actually under structural test.

None.

$ON (35.5), $TLN (37.3), $AVGO (38.7), $TXN (39.0), $ARM (39.2), $AMKR (39.5), $INTC (39.6) — seven names now sit in this band, the deepest the cut has been since tracking began. Most of these ($AVGO, $TXN, $ARM, $AMKR, $INTC) still carry a positive year-over-year return and sit at or above their 200-day; $TLN is the exception that fails the long-trend test outright.

• Genuine breakdown (below 200-day, negative or flat/lagging 1-year): $TLN, $CEG, $QCOM, $SWKS — four names, the only ones in the cut that fail the long-trend check.
• Deep pullback, long trend intact: $LSCC, $GEV, $BE, $AMAT, $MXL, $AMD, $TSM, $ASML, $NVDA, $MRVL — ten names, the bulk of the cut, all above their 200-day (or, for AMKR, still up triple digits over the year despite dipping below it) with solidly positive year-over-year returns.

• 19 of 20 names cooled this scan — does the group stabilize above its collective 200-day, or does the pullback deepen into a genuine breakdown for more names?
• $GEV and $TLN both dropped 15 RSI points from confirmed-uptrend status — $GEV is still well above its 200-day, $TLN is not; does either resolve toward the other?
• $MXL posted the cut's sharpest single-week decline (-21.4%) — does it find a floor near its 20-day, or does the drop extend toward its 200-day?
• $SWKS is flat-to-down on the year with a badly negative alpha despite sitting technically above its 200-day — does the price confirm the breakdown, or does the alpha catch up to the price instead?
