Investors are gearing up for a volatile trading day as key market indicators point towards a mixed outlook. While the S&P 500 closed marginally higher, attention is focused on upcoming inflation data that could sway market sentiment. Semiconductor stocks faced losses, with Micron and Nvidia seeing significant dips. The Federal Reserve's closely watched inflation measure is expected to show minimal monthly increase, potentially easing concerns. As the housing market starts to show signs of cooling off, prices are stabilizing and inventory is slowly increasing. Conversely, Walgreens suffered a sharp decline in shares after reporting disappointing earnings and a reduced profit outlook. The company cited a challenging retail environment as the cause. Overall, the market is uncertain, with factors like inflation data and company performance playing a crucial role in shaping investor decisions.
