Mid-Cap / Micro-Cap Top Movers of the Week |
Small-Cap Watchlist |
This week’s Russell momentum screen is AI supply-chain plumbing, one biotech data bomb, and two warning labels. |
$ICHR ( ▲ 3.28% ) : Ichor Holdings, $3B cap: This week’s top dawg jumped from #14 to #6, up +38% WTD and +371% YTD. Ichor makes subsystems for semiconductor manufacturing equipment, and its earlier guide called for sequential growth through 2026 tied to high-bandwidth memory, advanced logic, and packaging. Risk: it is still loss-making on a trailing basis, so the next guide has to carry the chart. |
$UCTT ( ▲ 3.88% ) : Ultra Clean, $4.9B cap: Ultra Clean jumped from #15 to #7, up +33% WTD and +330% YTD. The company supplies critical subsystems and services to chip-equipment customers, which puts it in the same AI fab-spend lane as Ichor. Risk: the stock has already outrun the small-cap label, and expectations now assume multi-year revenue acceleration. |
$TNGX ( ▲ 3.76% ) : Tango Therapeutics, $4.5B cap: New at #18, Tango ripped +53% WTD after early pancreatic cancer data showed responses in 11 of 12 evaluable patients. That is the cleanest non-AI catalyst on the board. Risk: the trial was small and uncontrolled, so Phase 3 is where the trade gets real. |
$NVTS ( ▲ 5.31% ) : Navitas Semiconductor, $5.5B cap: Navitas dropped from #12 to #21, down -6.7% WTD, despite the Nvidia MGX power-delivery story still pulling in 25.5k watchers. Risk: analysts still see 2026 revenue below 2025, while the stock trades like the 2028 ramp already happened. |
$AAOI ( ▼ 2.16% ) : Applied Optoelectronics, $13.6B cap: Applied Optoelectronics slid from #2 to #4, down -4.5% WTD, after a monster AI optics run. The 800G transceiver ramp is still the bull case. Risk: its $1B 2026 revenue target leaves no room for another customer or firmware hiccup. |
Next week’s swing factor: The June 16-17 Fed meeting. If rate volatility comes back, the unprofitable AI suppliers and biotech momentum names get tested first. |
