Apple and Palantir shares slide in premarket trading following post-bell earnings

Apple and Palantir shares slid in premarket trading Tuesday after both companies reported earnings following Monday's closing bell, with investors unimpressed by the results.

Apple, the iPhone maker, posted better-than-expected revenue in its fourth-quarter report. The stock still fell in early trading, a reaction that shows the revenue beat was not enough to satisfy the market. Palantir, the software company, also moved lower after its own post-bell release, putting both names under pressure at the same time.

Interpretation: the sell-off in Apple despite the revenue beat suggests investors were looking past the headline number. Expectations going into the prints may have been elevated, leaving little room for results that merely cleared the bar. Palantir's drop alongside Apple points to a shared reaction to earnings that failed to impress, rather than a reaction tied to a single company's revenue miss.

The premarket moves set the tone for Tuesday's regular session. Both stocks reported after the bell Monday, so Tuesday's open is the first full test of whether the early weakness holds or fades once regular trading volume arrives.
