According to Evan (@StockMKTNewz), Costco ($COST) reported May net sales of $19.64 billion, marking a 6.8% year-over-year increase (source: Twitter, June 4, 2025). Strong retail sector performance can signal improved consumer confidence and spending, factors that historically correlate with positive sentiment in risk assets including cryptocurrencies.
