The chip leg gave back the week to October 9 while power and fuel took it: 16 of 18 semiconductor names fell over five sessions ($ARM -13.4%, $AMKR -12.32%, $INTC -12.26%, $SWKS -10.21%) and the chip funds cooled from the high 60s to the low 50s on RSI, while 13 of 16 energy names rose, led by $TLN (+18.02%) and $CEG (+15.76%). No chip name has a negative year, and the only new 200-day loss was $ON's; $SMH and $SOXX remain about 20% above theirs. The extended names are now software, storage and fuel: $P (RSI 81.2), $PLTR (76.3), $ECO and $CVI.

Data as of the 2026-10-09 settled close; 38 unique tickers across the semiconductor, AI-infrastructure and energy lists (names in two lists appear once).

Chips took the week's damage. $SMH closed at $603.33 and RSI 53.0, -4.32% on the week, and $SOXX at RSI 51.7, -5.01%; a week ago both sat in the high 60s (68.6 and 66.6). Both remain 19.2% and 21% above their 200-day averages on years of +74.77% and +92.77%. Thursday's leg has a cause on file: the October 8 market brief records that the AI-hardware cohort sold as one after the Financial Times reported, and CNBC confirmed, that OpenAI told investors its annualized revenue was about $50 billion rather than the $68 billion to $70 billion widely cited; the semiconductor fund fell 2.84% that day and $NVDA 2.94%. The rest of the week's chip slide has no single receipt.

The deepest chip declines are pullbacks in strong years. $ARM fell 13.4% to RSI 43.9; it is 21% above its 200-day on a +56.03% year but 41.18% below its 52-week high, and the desk's thesis rating is intact but priced. A Benzinga piece dated October 8 had Arm down more than 3% in Thursday premarket after a 2.71% Wednesday decline, with Morgan Stanley holding an Equal-weight rating. $INTC fell 12.26% (RSI 43.4) and is still 26.1% above its 200-day on a +176.98% year; the October 5 brief tied that day's 2.63% drop to Elon Musk saying talks with TSMC on his Terafab chip project were ongoing (MarketWatch). $SWKS lost 5.45% on Friday and 10.21% on the week (RSI 41.3, 11.2% below its 20-day, 15.3% above its 200-day, +3.68% year); its news was last pulled September 16, so no cause is on file. $AMKR (-12.32%, RSI 42.7) is the weak one: 14.7% below its 200-day ($57.58) despite a +60.37% year, a long trend under test. $NVDA (RSI 53.0, -2.0% on the week) is 13.4% above its 200-day on a +19.06% year and 5.79% below its high. $AVGO, one of two chip names up on the week (+1.8%), is still 1.8% below its 200-day ($368.28); its first close back above it, noted in the October 6 brief, did not hold.

Power and fuel carried the other side. $CEG gained 15.76% on the week; the October 6 brief ties its 12.25% Tuesday to a Google power agreement that MarketWatch says equals a new reactor's output. $TLN gained 18.02% (RSI 69.4), including 12.43% on Tuesday that the same brief left unestablished because only aggregator pages offered causes, and they disagree. Both are now above their 200-day averages (4.2% and 7.6%) but down 22.22% and 14.83% on the year: repairing trends, not intact ones. Fuel names rose together: $XLE (+3.6%, RSI 61.5, 1.65% below its high), $XOP, $BP and $CRAK, with $ECO (+6.68%, RSI 73.7) and $CVI (+5.82%, 73.6) extended; the week included an October 8 oil jump that CNBC tied to stepped-up Iranian tanker attacks and a hurricane threat to Gulf production. $EOSE is the broken exception at $2.52: -9.03% on Friday, -21.5% on the week, RSI 28.7, 64.7% below its 200-day on a -82.79% year. Two trader-news pages dated October 8 tie that day's slide to a securities-litigation investigation into the company; Friday's drop has no dated item.

At the top, $P (Everpure, formerly Pure Storage) closed at RSI 81.2, +10.24% on the week and +59.17% over 30 days, 91.5% above its 200-day and 1.63% below its high; its news was last pulled September 30. $PLTR gained 5.17% on Friday and 10.75% on the week to RSI 76.3, 0.25% below its high; its year is +12.71% with slightly negative alpha, and the October 8 brief found nothing in its news on that day's government-compute rally.

• Extended band shrank and moved: 4 of 38 at RSI 70 or higher ($P, $PLTR, $ECO, $CVI), from 7 a week ago. $MXL, $TSM, $TXN and $AMD left it; $PLTR entered; $P went from extended to extreme.
• Oversold band reopened: $EOSE at RSI 28.7; none a week ago.
• Breadth: below the 20-day, 9 of 38 (10 a week ago); below the 200-day, 7 of 38 (9 a week ago); up on the week, 19 of 38, split 2 of 18 in semis, 6 of 11 in AI infrastructure and 13 of 16 in energy.
• Long-trend changes: $ON slipped below its 200-day (intact a week ago, now under test). $CEG, $TLN and $TAC moved above their 200-day averages on negative years (broken a week ago, now repairing).
• Universe unchanged: the same 38 tickers as the October 2 edition.

RSI under 30 is oversold, 70 and over extended, 80 and over extreme. The one-year return and the distance to the 200-day separate a pullback from a breakdown: above the 200-day on a positive year is intact; one test failed is under test or repairing; both failed is broken. A name more than 10% above its 20-day is treated as stretched even under RSI 70. The group column shows the source list; $NVDA, $ARM, $ASML, $MRVL, $TSM and $SMH sit in two lists and $TAC in both AI infrastructure and energy. This is price evidence, not a setup, with no fundamental or insider layer.

Zones are conditions (a level plus a confirmation), not orders. Levels are live-bound to the desk summaries.

• Chip funds: $SMH holding its 20-day ($597.06) keeps the week a pause inside a strong year; a slide toward its support shelf ($575.20) would deepen the pullback.
• $TSM and $ASML report into the chip pullback: ASML is scheduled for October 14 and TSMC for October 15.
• $ARM and $INTC: both are below their 20-day averages in strong years; a reclaim of the 20-day ($288.93 and $113.83) is the confirmation of a flag rather than a top.
• $AMKR and $ON: the 200-day averages ($57.58 and $81.14) are the lines; Amkor is scheduled to report on October 26.
• $AVGO: a second attempt above its 200-day ($368.28).
• $CEG and $TLN: whether a week of gains on hyperscaler power news turns into closes that hold above the 200-day; neither has a positive year yet.
• $P and $PLTR at or near their highs with RSI over 75: the first close below the 20-day marks the end of the run; no driver is on file for either.
• $EOSE: no floor identified; a broken trend with litigation headlines on file is not a setup.
