Market Volatility Amid Earnings Season Shift

Apple shares slid 1.9% after CEO John Ternus flagged rising memory costs as a threat to profit margins. Conversely, Deutsche Lufthansa climbed 4% following a successful quarter where revenue gains offset fuel spikes, while Koninklijke Philips jumped 5% on strong health-technology sales. AMD closed up 3.7%, with after-hours activity pushing gains to 7% as the firm solidifies its pivot toward data centers.

Palantir presents a distinct case of market skepticism. Despite reporting 96% revenue growth and doubling profits, shares slipped 1.7% as investors questioned the firm's $400 billion valuation. New contract signings fell to $2.9 billion from $3.4 billion, fueling debate over whether the company can maintain its rapid expansion. Meanwhile, Graphic Packaging’s rally serves as a reminder of the sector's fragility; despite the 21% jump, the stock remains down over 25% year-over-year following a turbulent period marked by executive turnover and ballooning construction costs at its Waco facility.
