Should l Buy COST?
Source: NASDAQ.COM
- Tariff Lawsuit Risk: Despite Costco's claim of not passing on the full tariff costs to consumers, a customer has filed a lawsuit seeking refunds, potentially leading to additional financial strain on the company.
- Stock Price Volatility: Costco's stock price has not moved significantly since the lawsuit was filed; however, the uncertainty surrounding tariff refunds may prompt investors to reassess its current high valuation, especially with a P/E ratio of 51.
- Stable Financial Performance: In the first half of fiscal 2026, Costco reported revenues of $137 billion, a 9% year-over-year increase, with profits of $4 billion, up 13%, demonstrating the company's resilience during economic fluctuations, but high valuations may cause investor unease.
- Long-Term Growth Outlook: Although facing challenges from tariff refunds in the short term, Costco is expected to continue its growth trajectory, and long-term investors should focus on its fundamentals rather than short-term fluctuations.

Is the Investment Opportunity in Costco Over?
- Membership Model Advantage: Costco's collection of membership fees creates an annuity-like income stream, allowing the company to compete aggressively on price, which attracts more customers and drives continuous revenue growth.
- Price Drawdown Analysis: Although Costco's stock fell nearly 20% in the second half of 2025, historical data shows that the stock has experienced drawdowns of 15% or more multiple times over the past decade, typically viewed as buying opportunities.
- Valuation Level Changes: Currently, Costco's price-to-sales, price-to-earnings, and price-to-book ratios are all above their five-year averages, indicating that the stock appears expensive under traditional valuation metrics, especially since the P/E ratio remained at 45x during the recent drawdown.
- Investor Recommendations: While Costco may still appeal to aggressive growth investors during drawdowns, caution is advised regarding its high valuation relative to historical levels and the broader market, suggesting it should be kept on a watchlist for future significant pullbacks.
