🔴 Onto Innovation is trading 8.1% down today amid pressure on semiconductor and AI shares

Onto Innovation is trading 8.1% down at $204.00, as semiconductor and AI-related shares face pressure; no company-specific catalyst has been confirmed.

• The selloff comes amid concerns about the sustainability of AI spending and renewed Middle East tensions; the iShares Semiconductor ETF was down more than 3% in premarket trading.
• The move also coincides with broader risk-off sentiment and weakness in technology shares. Available evidence points to sector pressure, not a confirmed Onto Innovation-specific announcement.
