Aehr Test Systems Sinks 10%, Teradyne Falls 5%, FormFactor Drops 6%: What’s Hitting These Semiconductor Test Equipment Stocks?
Semiconductor test equipment stocks Aehr Test Systems (AEHR), Teradyne (TER), FormFactor (FORM), and Cohu (COHU) fell 10%, 5%, 6%, and 6% respectively, due to profit-taking after strong year-to-date gains. No company-specific news was reported. Aehr's CEO sold 40,000 shares for $5.2 million, likely part of a preplanned diversification. The SPDR S&P Semiconductor ETF (XSD) declined 2%, indicating broader market resilience.
