Teradyne shares were sold off during the regular session, largely tracking a broader decline across the semiconductor equipment industry where peers like FormFactor, Lam Research, and KLA Corporation also saw significant losses. This downward move follows a period of volatility for the stock, which had jumped 8.3% on November 11 after Jefferies initiated coverage with a buy rating and a $284 price target, citing a potential $2 billion revenue opportunity from Nvidia. The stock's recent performance has also been influenced by shifting institutional sentiment, highlighted by a November 12 report that Cathie Wood's flagship fund exited its remaining position in the company. Despite the recent pullback, the firm continues to see positive analyst sentiment regarding its Q3 revenue growth and its expanding role in AI accelerator and high-bandwidth memory testing.
