Costco Wholesale Corporation Valuation Analysis
Costco trades at a price-to-earnings ratio of 47.30, a significant premium relative to the broader Consumer Defensive sector, according to SID market data. The stock's price-to-book ratio stands at 12.96, reflecting the market's high valuation of the company's asset base and intangible brand value. Costco's PEG ratio registers at negative 2.13, a metric distorted by the underlying growth rate assumptions in current estimates, per SEC filings. The company offers a dividend yield of approximately 0.57%, a relatively modest payout that aligns with Costco's historical approach of returning capital through periodic special dividends rather than elevated regular distributions. These valuation metrics collectively position Costco among the most premium-valued names in the consumer staples and warehouse retail space. Investors are effectively paying a substantial multiple for Costco's membership-driven revenue model and consistent operational execution over time.
Smart Money Activity for COST
Costco's composite smart money score sits at 46 out of 100, reflecting a neutral overall signal, according to SID market data. Institutional positioning is exceptionally strong, scoring a perfect 25 out of 25, indicating robust fund-level conviction in the stock. Congressional trading activity scores 12 out of 25, suggesting moderate engagement from lawmakers with disclosed positions. In contrast, insider activity scores 0 out of 25, the lowest possible reading. Per SEC Form 4 filings, there have been two insider transactions over the past 90 days, both of which were sales with zero insider purchases recorded during the period. Dark pool activity registers at 9.4 out of 25, indicating below-average institutional block trading relative to peers. The divergence between strong institutional holdings and weak insider buying presents a mixed signal, as company executives have been net sellers while large asset managers according to 13F institutional filings maintain significant allocations to the stock.
Costco Wholesale Corporation Earnings Outlook
Costco has delivered consistent earnings beats across its three most recently reported quarters, according to company earnings reports. In the quarter ending December 2025, the company posted earnings per share of $4.50, surpassing the consensus estimate of $4.36 by $0.14, representing the largest surprise magnitude among recent periods. The March 2026 quarter saw EPS of $4.58 versus the $4.55 estimate, a $0.03 positive surprise, while the May 2026 quarter produced EPS of $4.93 against a $4.92 estimate, a $0.01 beat. The narrowing surprise margins suggest analyst models are calibrating more precisely to Costco's performance trajectory. Looking ahead, per analyst estimates, the next earnings report is scheduled for September 24, 2026, with a consensus EPS estimate of $6.53, reflecting typical seasonal strength in Costco's fiscal first quarter. The sequential ramp from $4.93 to $6.53 implies meaningful expected acceleration.
