Nova (NVMI), Teradyne (TER), and Kulicke & Soffa (KLIC) saw notable share declines, caught in a broader semiconductor equipment selloff that has hit test, inspection, and packaging gear makers hard. The move appears sector-driven rather than single-stock idiosyncratic, putting all three in the same tape even though their underlying fundamentals diverge significantly.

Teradyne is the most defensible of the group on fundamentals: $3.2B in revenue growing 13.1% YoY, 58.2% gross margins, and $3.47 in diluted EPS. Kulicke & Soffa tells a harder story — revenue declined 7.4% YoY to $654M and net income for FY2025 was effectively zero, with diluted EPS rounding to $0.00, leaving virtually no earnings cushion. NVDA appears as enrichment context here, but the direct read-through is to end-demand for the equipment these companies sell into.

The bull case for TER on a dip is that a double-digit revenue grower with 58%+ gross margins rarely stays down in a sector selloff when end-demand (AI, advanced packaging) remains intact. The bear case is that if the macro or China-export-restriction overhang is the driver of the selloff, TER's relatively modest net margin (17.4%) offers limited downside protection and guidance risk could extend the drawdown.

KLIC is harder to defend: near-zero earnings on declining revenue means the stock is essentially a leverage play on a recovery in wire bonding and advanced packaging demand. Any further macro or capex-cycle softness compounds the downside with no earnings floor. Investors watching this space should track whether the decline is tied to a specific macro datapoint, export restriction headline, or simply sector rotation, as that changes the recovery timeline considerably.
