The week that was supposed to be about chips turned out to be about security: all four cybersecurity names finished in the board's top five gainers, led by Zscaler's +19.92% week that carried it from 3.2% below its 200-day average to 17.2% above it — the single largest structural repair on this board in this stretch. Tempus AI was the biggest mover outright, up 31.91% on the week with its RSI jumping 19.5 points to 67.8 and its 200-day cushion widening from +4.9% to +38.6%. The opposite corner belonged to telecom, which posted four of the board's five sharpest declines: Verizon fell 21.3 RSI points, BCE 20.5, T-Mobile 15.2 and AT&T 11.6, with no fresh news pulled on any of them to explain it. Constellation Energy extended its slide for a second straight week, down 10.55% and now 13.0% below its 200-day. All 67 names carry a settled Friday 2026-09-18 close.

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. Only price below the 200-day paired with a weak or negative year is real structural damage — that distinction is called out explicitly below wherever a trend flag might otherwise mislead.

The week opened with a scare and closed with a rally. Global AI stocks fell on Monday after leading AI figures endorsed slowing frontier-model development, prompting a chip selloff (Semafor, September 14). By Thursday the picture had inverted: the desk's September 17 brief records the broadest up day of the month, with the memory, AI storage, switch-and-NIC and semiconductor lanes all closing nearly unanimously green, and Nvidia's chief executive saying the company expects to sell twice as many chips next year across the coming six quarters. The Federal Reserve's quarter-point hike on Wednesday — its first in three years (Yahoo Finance, September 16) — sat in the middle of that and did not stop the complex from finishing higher. Thirty-five of the 67 names firmed on RSI, one was unchanged and 31 cooled — a majority up, but not a clean sweep.

Security was the week's real trade. Zscaler rose 19.92% and moved from 3.2% below its 200-day to 17.2% above it, the largest single structural change on this board; MarketWatch on September 17 carried an analyst arguing Zscaler was the one cybersecurity name that had missed the sector's rally and could still post big gains, which is the only dated item in its receipt that falls inside the move. CrowdStrike rose 14.95% with its 200-day cushion widening from 43.4% to 61.7%; its news receipt was pulled September 17 but its newest substantive item is the August 26 fiscal Q2 call, where the company reported a record $333 million in net new annual recurring revenue, up 51% year over year, and raised full-year net-new-ARR guidance — a strong standing fundamental, but dated well before this week, so the week's move itself has no sourced cause. Palo Alto Networks rose 9.96%; its own fiscal Q4 and full-year 2026 results release is dated September 15 in its receipt, citing nearly $1 billion of new annual recurring revenue and AI-driven demand. Fortinet rose 8.82% to RSI 58.0 and 49.1% above its 200-day, but its news was last pulled September 1 — news not pulled for this move.

Semis and memory extended rather than led. AMD rose 8.46% on the week and 20.02% over 30 days to RSI 65.4, now 57.9% above its 200-day with a +254.50% year; the dated item behind it is an AMD executive's projection that data-center revenue will more than double by 2027 (TheBuildout, September 14). Intel added 5.50% and 17.03% over 30 days with a +255.25% year. Nvidia firmed to RSI 54.2 and widened its cushion to 12.0%; its receipt, pulled September 17, carries a securities filing describing a definitive agreement to acquire Hugging Face. Micron rose to RSI 58.3 and 58.7% above its 200-day with a +501.46% year — and its next earnings print is scheduled for September 30 after the close per the desk's September 17 brief, which is the event that will test it. Seagate gained 6.93% on Friday alone. Qualcomm was the group's exception, falling 5.82% on Friday; its receipt's standing item is the fiscal Q3 report where revenue beat but earnings missed on Apple-revenue concerns (Investing.com, September 9), and nothing on file is dated to Friday.

Telecom and AI power were the two damaged corners. Verizon's RSI fell 21.3 points, the board's sharpest, and BCE's 20.5; T-Mobile lost 7.76% on the week and deepened to 12.9% below its 200-day with a -29.58% year; SK Telecom fell 5.20% but keeps the group's only clean long-horizon profile (+62.52% year, 12.7% above its 200-day). The news pulls for Verizon (July 14) and BCE (July 7) are months old and T-Mobile's newest item is dated July 23 — these are moves without receipts, not moves without causes. In power, Constellation Energy fell for a second straight week and is now 13.0% below its 200-day; Vistra lost 5.20% and sits 10.1% below its own; First Solar lost 6.25% and deepened to 14.1% below. Bloom Energy is the group's one clean holdout despite a -3.67% week: it is up 28.55% over 30 days, 33.6% above its 200-day with a +228.06% year, and is scheduled to join the S&P 500 before the open on September 21 per its news receipt (confirmed by S&P Dow Jones Indices, September 16).

Healthcare inside the complex was the quiet story. Intuitive Surgical rose 6.55% with its RSI jumping 13.1 points to 61.2 and its year improving from -19.02% to -9.75% — the longest-standing breakdown on this board finally repairing, though it remains 13.6% below its 200-day and is not repaired yet. Tempus AI's move is described above. Veeva held steady. In quantum and speculative AI, IonQ (+6.48%) and Rigetti (+3.21%) bounced while SoundHound fell another 5.27%; the whole cohort still trades between 10.8% and 39.2% below its 200-day, and the desk's September 17 brief separately notes that twelve of thirteen quantum names remain negative over 30 days — a bounce, not a turn.

1. The entire security group re-rated: ZS +17.5 RSI (45.8→63.3) and +19.92% on the week; CRWD +10.4 (50.0→60.4); FTNT +10.5 (47.5→58.0); PANW +10.1 (43.0→53.1). Every one widened its 200-day cushion materially.
2. ZS crossed from below its 200-day to well above it: -3.2%→+17.2%, with its year improving from -42.60% to -32.22% — the board's largest structural repair.
3. TEM posted the board's biggest move: +31.91% on the week, RSI +19.5 (48.3→67.8), 200-day cushion +4.9%→+38.6%, year -33.53%→-10.60%.
4. Telecom collapsed across four names: VZ -21.3 RSI (63.3→42.0), BCE -20.5 (53.0→32.5), TMUS -15.2 (51.5→36.3), T -11.6 (61.9→50.3).
5. CEG extended its breakdown for a second straight week: RSI -17.3 (53.7→36.4), vs its 200-day -3.6%→-13.0%, year -10.46%→-21.07%.
6. ISRG began repairing: RSI +13.1 (48.1→61.2), year -19.02%→-9.75%, 200-day gap -19.7%→-13.6% — still below the line.
7. AMD extended hard: +8.46% on the week, +20.02% over 30 days, 200-day cushion 48.8%→57.9%, year +231.55%→+254.50%.
8. PANW's cushion widened by 11 points: 40.1%→51.1%, on its fiscal Q4 and full-year 2026 results.
9. The oversold band rotated again, 5 names to 7: RUN and OKLO climbed out; BCE, TMUS, CEG and ENPH fell in; NEE, SOUN and PATH stayed.
10. QCOM gave back last week's standout move: RSI -12.3 (66.3→54.0), year +12.67%→+5.70%.
11. MDB recovered sharply: RSI +6.1 (42.4→48.5), +5.89% on the week, 200-day cushion 5.6%→11.4%, year +9.07%→+21.26%.
12. NVDA reversed last week's cooldown: RSI +4.4 (49.8→54.2), cushion 10.5%→12.0%, year +23.21%→+26.12%.
13. No name on this board is overbought: TEM's 67.8 is the highest reading, against META's 67.2 top last week.

RSI below 25 is capitulation. RSI 25-40 is oversold — check the trend and the long-horizon numbers before treating it as a buy signal, because several names here fell into this band on one bad week while remaining well above their 200-day. RSI 40-70 is neutral-to-healthy, above 70 is extended. "vs SMA" is distance from the 20-day average, short-term positioning only. "1Y%" and "vs SMA200" are the long-horizon check: a red short-window trend flag paired with price above the 200-day and a positive year is a deep pullback, not a breakdown; the reverse is real structural damage. Where a cause is named below it comes from a dated item in that name's news receipt or a dated capture; where the receipt is stale or failed, the scan says "news not pulled for this move" rather than implying nothing happened.

Read: AMD and Intel are carrying this group on historic years, both widening their cushions. Nvidia reversed last week's cooldown. Broadcom remains the group's one name below its 200-day, and with its year at just +3.55% it is the closest here to converting into genuine damage.

Read: All three continue to hold extraordinary trailing years with large cushions. Micron's September 30 print after the close is the scheduled event that will test the group.

Read: Meta's 30-day gain of 21.93% keeps widening its cushion while its year stays deeply negative — the healing continues, the repair is not done. Tesla's year deteriorated sharply this week, from -0.91% to -12.61%, and it stays below its 200-day: this is the group's one genuine long-trend problem.

Read: This was the week's trade. All four names posted large advances and all four widened their 200-day cushions; three of the four carry years between +76% and +110%. Zscaler is the exception in kind — its year is still -32.22%, so its move is a repair from a deep hole rather than an extension of strength, and its 200-day at 17.2% below Friday's price is the line that now has to hold.

Read: MongoDB and Cloudflare were the group's strong movers; Palantir's 6.22% week is notable only against a year that is still flat at +0.38%. The two names to watch are the data-center REITs on opposite trajectories — Digital Realty's cushion is down to 1.2% after a -3.43% week — and UiPath, falling a fourth straight week with its cushion down to 3.7%. Adobe stays the group's confirmed breakdown.

Read: This is the board's damaged corner and it got worse. Eleven of twelve names sit below their 200-day; ten carry a negative year. Constellation Energy's second straight collapse is the group's headline and it now sits 13.0% below its 200-day with a -21.07% year. Bloom Energy is the sole clean leader — up 28.55% over 30 days with a +228.06% year — and its S&P 500 addition is scheduled for September 21, which is an index-flow event, not a fundamental one.

Read: Tempus was the board's biggest mover and its 200-day cushion went from +4.9% to +38.6% in a week — a violent re-rate off a deep base, with a partially sourced cause and a year still at -10.60%. Intuitive Surgical's repair is the more durable story to track: RSI up 13.1 points and its year cut from -19.02% to -9.75%, but 13.6% below its 200-day is still 13.6% below.

Read: Three of five bounced on the week and every one remains between 10.8% and 32.6% below its 200-day with a double-digit negative year. The desk's September 17 brief records twelve of thirteen quantum names still negative over 30 days — this cohort's up days keep failing to change its month.

Read: The whole group fell and four of five fell hard. Verizon still passes the long-horizon check (+10.12% year, 4.3% above its 200-day) so its 21-point RSI drop reads as a violent pullback inside an intact trend; T-Mobile and BCE do not, and both deepened. What is missing here is evidence: the news pulls for Verizon and BCE are from July and T-Mobile's newest item is dated July 23, so no receipt on this desk speaks to this week's decline in any of them.

Read: The two AI-weighted funds held their leadership; the two robotics funds did not. BOTZ's year has fallen to +0.23% while sitting 4.9% below its 200-day, and ROBO is now only 0.9% above its own. The robotics expression is decoupling from the AI expression.

Read: SK hynix's US listing is still too young for a long-horizon read; its 20.07% month is real but unclassifiable against a trend. Treat any short-window signal here as provisional.

None on this board.

Seven names: BCE (32.5), NEE (32.7), SOUN (34.5), TMUS (36.3), CEG (36.4), ENPH (38.7), PATH (39.0). The band rotated again — RUN and OKLO climbed out; BCE, TMUS, CEG and ENPH fell in; NEE, SOUN and PATH held their places. Only NEE and PATH still carry a positive year, so five of the seven are oversold and damaged, a worse composition than last week's five.

The remaining 60 names, led by TEM (67.8), META (65.8), AMD (65.4), ZS (63.3), INTC (61.7) and ISRG (61.2). No name reads above 70.

• Whether the security re-rate holds a second week. The specific level: Zscaler moved from 3.2% below its 200-day to 17.2% above it in five sessions, so a give-back of that size returns it to a breakdown — this is the board's most reversible move.
• Whether Tempus AI's 31.91% week survives a retest. Its cushion went from +4.9% to +38.6% and its year is still -10.60%; a move that large off a deep base with only a partial sourced cause needs a second week before it means anything.
• Whether telecom's collapse gets an explanation. Four names fell hard with no fresh news pulled on any of them — the question is whether a sector cause surfaces or whether it resolves as a rate-driven repricing alongside utilities and real estate, which fell the same week.
• Whether Constellation Energy finds a floor. Two straight weeks of decline have taken it to 13.0% below its 200-day with a -21.07% year, and nothing beyond the September equity raise is on file.
• Whether Broadcom converts. It is the semis group's only sub-200-day name with a year down to +3.55% — the closest name in that group to crossing into confirmed damage.
• Whether the two data-center REITs diverge further. Digital Realty's cushion is down to 1.2% and Equinix's to 4.9%, both after negative weeks, in a complex whose physical build-out is the dominant theme.
• Whether the robotics funds' decoupling from the AI funds continues: BOTZ at +0.23% on the year and 4.9% below its 200-day against AIQ at +31.47% and 13.3% above is a widening split inside what is nominally one theme.
