After-hours stock moves: Palantir, Pinterest, Duolingo, Paramount Skydance and more

Post-earnings stock moves drive sharp gains and losses after the bell See which large-cap names beat forecasts, missed guidance, and surprised investors

Several largecap and midcap stocks moved sharply after the closing bell on Monday as investors reacted to fresh quarterly results and updated forecasts. Paramount Skydance rose about 2% after reporting firstquarter adjusted earnings and revenue that came in ahead of analyst expectations. Pinterest gained 15% after its secondquarter revenue guidance topped forecasts and its firstquarter results also beat estimates. Other notable movers included Duolingo, which fell about 13% after monthly active users missed estimates and its secondquarter bookings outlook disappointed. Palantir slipped nearly 3% despite beating on earnings and revenue, while Sonos, Firefly Aerospace, Diamondback Energy, IAC, ON Semiconductor and Fabrinet also saw outsized moves following earnings updates and guidance changes.
