Summary
The same AI-financing unwind that repriced the compute landlords is now washing out the desk's covered picks-and-shovels lanes — semiconductor test, machine vision, defense photonics, connectivity silicon, and gas-fired power. But there's a divergence hiding inside the drawdown: the fundamentals wire fired margin-inflection signals on almost every one of these names as the tape sold them off. When prices fall while operating leverage turns up, that's a shopping list, not a warning. Five names earn a buy-on-trigger (TER, CGNX, LASR, CRDO, KGS), two earn a watch (MXL, EQT), and one collapsed parabolic earns a pass on the record (AXTI).
Falling prices, rising margins
| Ticker | Lane | Price (Jul 7) | 7d | Off 52wk high | What the wire fired | NOTE |
|---|---|---|---|---|---|---|
| TER | test (physical-AI) | $343.11 | −21% | −30% | margin inflection | no company event behind the drop — Q1 revenue +87% YoY, EPS beat by 21% |
| CGNX | machine vision | $64.21 | −2% | −12% | +6.6pt margin | EPS $0.10 → $0.20 → $0.31 across three quarters |
| LASR | defense photonics | $59.01 | −2% | −32% | margin inflection | swung to GAAP profit; record defense revenue nearly doubled to $33.1M |
| CRDO | connectivity silicon | $246.40 | −3% | −20% | — (screen: basing) | FY26: $1.34B revenue, 33% operating margin, $472M net income |
| KGS | gas power | $68.01 | −12% | −12% | margin inflection | raised FY26 guidance; 300–500MW/yr power-gen growth through 2030 |
| MXL | connectivity silicon | $85.82 | −16% | −33% | margin inflection | already a 4.5x on the year; the give-back has no news behind it |
| EQT | nat gas | $51.76 | −2% | −24% | +30.6pt margin | best fundamentals in the sweep, weakest tape — below its 200-day |
| AXTI | III-V substrates | $58.15 | −11% | −59% | — | collapsed 25x parabolic; sub-$100M revenue, operating losses |
The pattern to respect: TER, CGNX, and LASR all beat their last print decisively — Teradyne's Q1 revenue rose 87% year-over-year with a $0.45 EPS beat (MarketBeat), nLIGHT swung to GAAP profit on +55% revenue with defense product sales nearly doubling (24/7 Wall St), and Cognex's earnings tripled across three quarters on the wire-flagged margin expansion. None of the three has adverse company news behind its pullback. The drawdown is the sector's, not theirs.
The two stories worth singling out
KGS (Kodiak Gas Services) is the origination find of the sweep — a datacenter-power story wearing a gas-compression wrapper. Q1 delivered record Contract Services revenue of $307M, adjusted EPS of $0.59 (a beat), a $50M buyback — and management raised full-year guidance to fold in the Distributed Power acquisition, guiding to 260+MW of additional power-generation capacity now and 300–500MW of annual growth through 2030 (company release via OTC Markets, MarketBeat). That's the electricity pillar's thesis showing up in a name nobody covering "AI power" talks about. The week's −12% came with the energy tape, not the story.
CRDO (Credo) is what quality looks like in this cohort: $1.34B of FY26 revenue at a 33% operating margin with $472M of net income and $1.4B of cash (SEC EDGAR XBRL, fiscal year ended 2026-05-02) — an optical/connectivity grower that is already a compounder, not a promise. Its pullback is the shallowest in the sweep, which is exactly what relative strength during a sector washout looks like.
Why triggers, not market orders
Every buy here is on-trigger because the lanes are mid-washout and the desk doesn't catch knives: the entry levels are the moving-average or volume-structure reclaims that say the flag held (tape and levels from the desk summaries, 2026-07-07 close). If the unwind deepens instead, the invalidation lines say so and nothing was bought. Both outcomes are on the record either way — including the AXTI pass, which is wrong (and will be scored as wrong) if the substrate cycle builds a durable base.
