See our latest analysis for Costco Wholesale.

Costco’s slight dip this week follows a broader trend of cooling momentum, as its 30-day share price return is down 3.35% and gains year-to-date are now just 1.45%. Still, the company’s long-term performance remains impressive, with a 2.28% total shareholder return over the past year and a remarkable 162.66% gain over five years. This reminds investors why it is often viewed as a reliable name through market cycles.

Costco plans to continue expanding its warehouse locations, with 28 new openings planned for fiscal year 2025. This expansion is likely to increase membership and sales volume, driving revenue growth.

Another View: Valuation by Earnings Ratio

Looking at Costco’s price-to-earnings ratio offers a different angle. Shares trade at 50.5 times earnings, which is much higher than both the consumer retail industry average of 19.8x and the peer average of 22.4x. The fair ratio, calculated at 33.3x, suggests Costco is currently expensive by this metric. This large gap hints at increased valuation risk if market sentiment cools. Can these premium expectations truly last?
