Costco stock has continued its strong performance into earnings, currently trading around $1,008, up approximately 10% year-to-date. Shares recently pushed above the $1,000 mark, a level that has reignited talk of a potential stock split among investors. Technically, the stock remains in a strong uptrend and near all-time highs. From a valuation standpoint, Costco trades at over 50x trailing earnings, with a forward P/E around 42x, making it one of the more expensive large-cap retailers. Bulls justify this multiple by pointing to consistently high renewal rates, low churn, and operational discipline. However, any margin pressure or weaker comp figures could prompt valuation re-rating.
