Amtech, Semtech, Nova, Power Integrations, and FormFactor Shares Are Falling, What You Need To Know
U.S. announced new Section 301 tariffs of 10% to 12.5% on 60 trading partners, including the EU, Japan, South Korea, and Taiwan, citing forced labor concerns. The move raised expectations of long-term margin compression and triggered a broad semiconductor sell-off. Shares of ASYS, SMTC, NVMI, POWI, and FORM fell 3.2% to 5% in the morning.
How this was made

The 30-second read
Why it matters
The tariff announcement is framed as legally durable, leading investors to price long-term margin compression across U.S. semiconductor hardware and related supply-chain participants, triggering a broad selloff.
Market read
This is a multi-name semiconductor risk-off move tied to a fresh tariff headline, with the same catalyst driving each stock’s morning decline.
What to watch
No company-specific mitigation is provided. Traders should watch for tariff scope details, timing of implementation, and whether earnings guidance already assumes similar cost headwinds.
Background
The U.S. announced new Section 301 tariffs of 10% to 12.5% on 60 trading partners, citing forced-labor concerns, targeting major semiconductor supply-chain regions.
Ticker impact
Amtech (ASYS) fell 3.2% after the U.S. announced 10% to 12.5% Section 301 tariffs tied to forced-labor concerns.
Near-term downside bias as investors price longer-duration cost pressure across semiconductor hardware.
The article attributes the morning selloff to new durable tariffs on key semiconductor partner regions, which can raise imported input costs and reduce margins for the sector.
Semtech (SMTC) dropped 5% in the morning session following the U.S. tariff announcement on 60 trading partners over forced-labor concerns.
Volatile, risk-off trading likely until tariff implementation details and earnings sensitivity are clearer.
The text frames the move as a broad semiconductor rout triggered by legally durable Section 301 tariffs affecting the supply chain.
Nova (NVMI) fell 4.1% as investors reacted to new 10% to 12.5% tariffs on semiconductor supply-chain partner countries.
Short-term pressure likely, with potential stabilization only if tariff impact is offset by pricing or demand resilience.
The article does not cite NVMI-specific fundamentals, but directly links the sector selloff to tariff fears.
Power Integrations (POWI) declined 3.8% during the morning selloff after the U.S. announced Section 301 tariffs on key semiconductor partner regions.
Negative bias for the session and possibly subsequent days if tariff headlines persist.
The tariff announcement is presented as the primary catalyst for broad semiconductor weakness, with no POWI-specific offset mentioned.
FormFactor (FORM) slid 4.3% as the market priced in durable Section 301 tariffs that could compress margins across U.S. semiconductor hardware.
Likely underperformance versus peers until investors reassess earnings sensitivity to tariff-driven cost inflation.
The article’s newest concrete fact is the tariff announcement, and it explicitly ties the broad selloff to long-term margin compression across the sector.
Market effects
Tariffs on EU, Japan, South Korea, and Taiwan raise the probability of sustained margin pressure across semiconductor hardware and OSAT-linked supply chains.
Reinforces a broader global chip rout that began overnight with Asian memory/semiconductor leaders (Samsung, SK Hynix).
Could propagate through global semiconductor pricing, capex expectations, and supply-chain cost structures for imported inputs and equipment.
Counterpoint
The article argues the market may overreact; if companies can pass through costs or if demand remains robust, the selloff could be an opportunity rather than a fundamental break.
