Costco posts fifth straight earnings beat but trades at high valuation, limiting upside potential.

Costco reported its fifth consecutive quarterly earnings beat, driving an 8.93% stock gain over the past month. The company showed strong revenue growth, rising membership renewals, and robust free cash flow, supporting its defensive retail profile. However, its high valuation with a trailing P/E of 48 and forward P/E of 40 leaves little room for error, making the stock a Hold rather than a Buy. Investors should watch membership growth, comparable sales, and margin trends for signs of further upside or risk of multiple compression.

Costco shares are currently priced at USD 1,000.13 on Pluang, showing a slight decline of 0.50% in the last day. As of Oct 27, 2026 19:33 WIB, the stock has a market cap of $445.42 billion and a dividend yield of 0.58%.
