The Velocity is in the layer of the stack that gets paid first in an AI build-out — the silicon and the machines that make it. The exhaustion is in the layer that pays for it.
Nine of the twenty-four confirmed Deep Positive Reversals in semiconductors, equipment and hardware, ranked by depth of the turn. Memory, foundry and the test/materials layer all appear, which is what makes this a supply-chain-wide read rather than a handful of names. Reference bands are the model’s trading levels from the 18 Sep close.

Street Corroboration — Third-Party Consensus, Not Quantmatix Output
The figures below are third-party analyst consensus data, sourced from external providers and shown for context only — they are not Quantmatix model output and are not endorsed by Quantmatix. Shown against the 18 Sep close, for the names carrying the deepest turns above.

Consensus Δ |
Analyst View |
| Micron | $1,015.80 | +52% | Strongly positive (58 · 10 · 2) |
| Arm Holdings | $275.61 | +32% | Positive-tilted |
| Analog Devices | $375.72 | +28% | Positive-tilted |
| Teradyne | $371.47 | +24% | Positive-tilted |
| Coherent | $317.36 | +23% | Positive-tilted |
| Marvell | $244.25 | +11% | Strongly positive (60 · 12 · 1) |
| Qualcomm | $177.72 | +15% | Split — Street still cautious (30 · 34 · 5) |
Qualcomm is the point of interest: the model carries the sharpest weekly acceleration in the group (ΔQ +1.9) while the Street remains split (30 positive · 34 neutral · 5 negative). That places the model’s read ahead of consensus rather than behind it — an earlier reading, not a confirmation of the Street’s view. Micron carries both the strongest consensus positioning and a fresh model turn into its quarter, addressed below.
The Other Side — Software High-Score Negative Reversals
|
Twenty-four names in Software & Services carry a confirmed High-Score Negative Reversal (Q +7 to +10, turning down), against four Deep Positive Reversals in a group more than twice the size of semiconductors and hardware combined. These are exhaustion signals on names that have run hot, not fresh negative calls — a relative read that momentum is leaving application software for the layer underneath it.

Early Warnings — Q Signals, Not Yet Confirmed
A Q Signal is the model’s earliest-stage warning of a potential reversal — a different, earlier read than a confirmed reversal, and not a directional recommendation. Two are notable this week, one at each end of the stack. GLOBALFOUNDRIES is flashing a positive Q Signal while Advancing at Q −8.9 — a foundry name at the very bottom of the band, the earliest possible stage of the same turn showing across the chip cluster. DXC Technology is flashing a negative Q Signal at Q +9.0 and Declining — an early warning at the top, consistent with the software rollover.

The Thread — One Story
The technology turn is narrow and specific: it sits in the chips, not the software, and it follows where AI infrastructure spending is landing — memory, custom silicon, foundry and the equipment layer, turning up from the bottom of the score band with no exhaustion anywhere in semiconductors. Consensus already sits above price on the marquee names, and on Qualcomm the model is reading ahead of a still-cautious Street. The other side of the same read is the software rollover: infrastructure spend is taking budget from applications, and that is where the High-Score Negatives are concentrated. The Velocity is in the layer that gets paid first; the exhaustion is in the layer that pays.
A Q Signal is an early warning of model state, not an instruction to transact. Reference bands, close prices and reversal flags are subject to change with each nightly scoring run. The levels behind every name mentioned here are set out in the full research.

What Would Flip the Read
The view changes if any of these turn: semiconductor breadth rolls back over (Advancing share falling from 60% while scores stay negative — a failed turn); the deepest-turn names slip back to Declining (Cirrus Logic, MACOM, Rambus, Qualcomm); Micron’s quarter breaks the memory read and the cluster loses its footing; or software stops rolling over and the High-Score Negative cluster switches back off, which would say the rotation down the stack has stalled.

Data & method. The Q Score is a proprietary measure of Velocity (Direction and Momentum), −10 (deeply beaten down) to +10 (stretched), computed here on the weekly (medium-horizon) timeframe across 606 technology instruments. A Q Signal is the model’s earliest-stage warning of a potential reversal (not a directional recommendation); a Deep Positive Reversal is a confirmed positive reversal on a Q Score of −4 to −10; a High Score Negative Reversal (HSNR) is a confirmed downward turn from a Q Score of +7 to +10. Reference bands (Upside Ref. / Mean Ref. / Downside Ref.) are the model’s trading bands from the 18 Sep close and are estimates, not forecasts or guarantees. Third-party consensus targets and analyst ratings are shown for context only, sourced from external data providers, and are not Quantmatix output. All figures are Quantmatix data as at 18 September 2026 and subject to change with each nightly scoring run.
