The Consumer Discretionary sector surged in after-hours trading, driven by blockbuster second-quarter earnings from Amazon (AMZN), the sector's largest component. Amazon reported revenue of $200.6 billion and a 37% year-over-year increase in its AWS segment sales, significantly beating expectations. The strong results, which caused AMZN shares to jump over 9% in the after-hours session, signaled underlying strength in both consumer spending and cloud services, lifting the broader sector.
