With Costco Down 7% From Its All-Time High, Could Buying Now Set You Up for Life?

Costco has delivered a 688% total return over the past 10 years, but the article argues the stock is too expensive at 52.2x earnings and nearly 7% below its February 2025 peak. The company still has a solid growth runway, with plans to open 30-plus net new warehouses annually and a 189% dividend increase over the past decade. Overall, the piece is a valuation-focused caution that recommends investors wait for a pullback rather than buy now.

Analysis

The market is treating COST like a bond proxy with operating leverage, which is the wrong mental model at this valuation. At ~52x earnings, the stock is pricing in not just durable comp growth, but sustained margin stability despite increasing wage, occupancy, and membership renewal pressure; that leaves the equity highly sensitive to any normalization in traffic mix or merchandising spread. The bigger second-order issue is crowding: when a defensive compounder becomes consensus-ownership-heavy, even a modest growth deceleration can trigger multiple compression before fundamentals actually break.

The key bullish counterargument is that Costco’s real option is not same-store sales, but warehouse rollout plus membership monetization, which can extend the runway for years. That said, the rollout pace implied here is incremental, not transformative, relative to the current base; a few dozen openings per year meaningfully support earnings, but they do not justify paying for venture-style terminal growth. Investors should focus on the gap between operating execution and expectation embed: the stock can stay expensive, but it does not need to re-rate higher to become a poor forward return candidate.

The contrarian nuance is that the best short in high-quality retail is usually not outright on the business, but on timing and valuation. COST is vulnerable to any macro tape where consumers trade down less than feared but still become more price-sensitive, because that preserves traffic while compressing basket economics. If the next two quarters show even slight membership or margin disappointment, the stock can de-rate faster than consensus expects because there is little valuation air gap left.

Key Decisions for Investors

• Avoid initiating new long exposure to COST at current levels; if already held, consider trimming 25-33% into strength over the next 2-6 weeks to reduce multiple-compression risk.
• Express a relative-value view: long BRK.B / short COST in equal dollar terms for 3-6 months. BRK.B offers quality with a materially lower multiple and less downside if growth normalizes; risk is COST continuing to melt up on defensive rotation.
• For investors who need retail exposure, use a pullback entry only after a 10-15% drawdown from current levels. Target an entry where forward P/E is closer to the mid-40s rather than low-50s to restore some margin of safety.
• Consider a limited-risk bearish options structure in COST over the next 1-2 earnings cycles, such as a put spread financed partly by selling out-of-the-money upside. This captures valuation compression while capping premium bleed if the stock remains rangebound.
• Watch for any sign of membership growth or renewal-rate inflection over the next 1-2 quarters; that is the main catalyst that could invalidate the cautious stance and justify re-adding exposure.
