# Pre-market Briefing | Amazon Surges 15%, Apple Plunges 7%, AI Returns Repriced

**Amazon surged 15%, while Apple plunged 7%: The market is recalculating the return on every dollar invested in AI.**  

Amazon's earnings report beat expectations across the board, with AWS growth acceleration driving its stock to one of the largest single-day gains since 2012; on the other side, Apple fell due to Q4 guidance, supply constraints, and margin pressure. Meanwhile, **optical communication stocks** rallied across the board, with **AXTI** surging 28.74%, while memory chips continue to cool off.  
**Tonight also features the U.S. Manufacturing PMI and Palantir's after-hours earnings report**; **this week, AMD, WDC, SNDK, and non-farm payrolls data will take turns hitting the stage**. Two pages of pre-market briefing to help you quickly understand the most noteworthy events, sectors, and unusual movers before the open.
