Boeing Drops, Ultra Clean Surges, PPG Industries Rallies

Today's biggest gainers and decliners in the stock market.

On this episode of Stock Movers:

- Boeing (BA) cut its full-year aircraft delivery target and said it needs more time to accommodate higher production rates, a surprise reversal that sent the stock tumbling to an 18-month low. The shares dropped as much as 10%, the most since April 2025 and closed down 11%, notching its worst day of trading since June 2020. The dramatic market reaction shows how investors remain on edge about Boeing’s recovery after years of struggles to get the planemaker back on track.

- Ultra Clean (UCTT) shares rallied 10% in extended trading after the semiconductor equipment company reported adjusted earnings per share for the third quarter that beat the average analyst estimate.

- PPG Industries (PPG) shares are up 7.5% in extended trading after the paint and coating manufacturing company raised the low end of its adjusted earnings per share forecast for the year.
