On May 20, FormFactor rose 5.55% in regular trading, trading at $124.65/share, with trading volume of $45.60 million, ending a sustained pullback that began on May 12.

On the news front, the rebound comes after consecutive sessions of profit-taking following a strong post-earnings rally. FormFactor previously reported robust first-quarter results, with revenue reaching $230 million and gross margin improving 5.1 percentage points sequentially to 49.0%, exceeding the high end of guidance. The company also raised its second-quarter outlook, with CPO-related revenue trending toward the high end of its $10 million to $20 million target range. The stock had seen significant selling pressure over the prior week as investors locked in gains from the post-earnings surge.

The broader semiconductor equipment sector provided additional tailwind, with Lam Research up 3.48%, ASML up 2.96%, Applied Materials up 2.78%, and KLA-Tencor up 2.72%, creating a favorable backdrop for FormFactor's technical recovery.
