Amazon (AMZN) was the standout mover of the session, climbing 15.25% to close at $271.41 — a dramatic single-day gain that underscores how much riding on earnings results can separate winners from losers in the mega-cap space. Google also had a strong showing, with both GOOG and GOOGL shares rising roughly 6.7%, closing at $356.02 and $355.78 respectively, reinforcing the sense that cloud and advertising-driven businesses are rewarding investors this earnings season.

On the losing side, Apple fell 8.4% to $305.42, a sharp reversal that signals investor unease about whether the broader mega-cap rally has legs beyond the names that beat expectations. Novo Nordisk was the session's steepest percentage decliner, off 9.33% to $46.80, while electric vehicle names Lucid and Rivian also slid, losing 9.3% and 7.87% to close at $7.37 and $15.51 respectively.
