The consumer discretionary sector is experiencing a significant rally, largely driven by strong quarterly earnings reported by Amazon (AMZN). The e-commerce and cloud computing giant's shares surged in pre-market trading after beating earnings expectations. This positive momentum for a key sector heavyweight, coupled with a broader market rebound following the Federal Reserve's decision to hold interest rates steady, is lifting the entire sector. Positive earnings from other consumer companies like Newell Brands (NWL) also contributed to the upward trend.
