Why FORM stock is down today

FormFactor Inc stock fell 12.03% to $121.54 in early trading. The decline followed a negative gap open and a broader market backdrop where investor sentiment in the semiconductor sector remained mixed. The stock opened at $131.20, but quickly declined through the session as selling pressure intensified.

What Happened

The session began with a -5.0% gap down from the prior close of $138.16. The stock reached an intraday high of $131.20 at 7:00 AM ET but continued to weaken, hitting a low of $121.49 by 11:00 AM ET. The decline occurred amid analyst activity, with TD Cowen lowering its price target to $100 and maintaining a Hold rating, while Evercore ISI Group also reduced its price target to $150 but kept an Outperform rating. These adjustments suggest a cautious outlook on the stock despite some positive sentiment in the broader chip sector.

Recent insider transactions also contributed to the sell-off. The CEO, Mike Slessor, and other insiders have sold shares in multiple transactions over the past two months. The most recent SEC Form 4 filing showed $6.3 million in insider sales over the last 90 days, with no insider purchases recorded. These actions may have signaled a lack of confidence in the near-term stock price.

What The Data Shows

The stock has traded between $27.00 and $160.27 over the past 52 weeks. With a market cap of $9.0 billion and a P/E ratio of 88.9, the company is valued for growth. However, the recent drop has pushed the stock closer to its 52-week low. The session has seen 0.3 million shares traded, which is 0.2 times the 3-month average volume. On August 18, the stock printed one fresh 52-week high and 21 fresh 52-week lows, showing a mixed market environment.

What To Watch

FormFactor does not have an upcoming earnings date disclosed in the provided data. However, investors should monitor the breadth of coverage and any new analyst ratings or price target changes in the coming days.
