This week, Costco Wholesale ($COST) is set to report its earnings, which are due after Thursday's market close. As of February 28, Costco's market capitalization stood at $465.5 billion, with its stock price at $1,048.61, reflecting a 2.6% increase on Friday and an overall rise of 14.4% in 2025, following a 38.8% increase in 2024. The retail sector is under scrutiny as Walmart ($WMT) recently reported disappointing earnings, raising concerns about consumer spending. Analysts are closely watching Costco and other retailers, including Target ($TGT), as they navigate a challenging market environment characterized by declining consumer confidence. Target has also reported weak sales figures for February and anticipates slow growth for the year, adding to worries about the health of US shoppers and the broader economy.
