Costco Wholesale Corporation Stock Performance
Costco Wholesale Corporation shares traded at $901.35, up 0.12% on the session, per SID market data. The stock has declined 4.46% over the past month and 6.46% over the trailing three months, though it maintains a positive 5.09% gain over the past twelve months. COST is currently trading below both its 50-day moving average of $940.13 and its 200-day moving average of $978.13, indicating sustained downward pressure across multiple timeframes. The 14-day relative strength index registers at 25.5, placing the stock in oversold territory below the conventional 30 threshold, according to Massive/Polygon technical data. Average daily trading volume stands at approximately 2.52 million shares. Costco carries a beta of 0.982, reflecting near-market-level volatility consistent with its Consumer Defensive sector classification. The company's market capitalization currently stands at approximately $392 billion.
Costco Wholesale Corporation Valuation Analysis
Costco Wholesale Corporation trades at a price-to-earnings ratio of 47.30, a significant premium relative to the broader Consumer Defensive sector, per SID market data. The company's PEG ratio registers at -2.13, reflecting a negative forward growth adjustment that complicates traditional growth-at-a-reasonable-price assessments. Costco's price-to-book ratio stands at 12.96, underscoring the market's substantial premium over the company's reported book value, according to SEC filings. The current dividend yield is 0.57%, a modest income component relative to the stock's elevated earnings multiple. The combination of a high P/E ratio with a below-1% dividend yield positions Costco as a growth-oriented holding within a traditionally defensive sector. The company's valuation metrics reflect the market's pricing of Costco's durable competitive advantages, including its membership-based revenue model and consistent same-store sales performance. These multiples remain elevated even as shares have pulled back from recent highs.
Smart Money Activity for COST
Costco Wholesale Corporation's composite smart money score stands at 46 out of 100 with a neutral signal, per SID market data. Institutional positioning scores a perfect 25 out of 25, reflecting robust ownership from large asset managers and funds. In contrast, insider activity scores 0 out of 25, with two insider transactions recorded over the past 90 days—both of which were sales with zero insider purchases, according to SEC Form 4 filings. This sell-only insider pattern indicates that company executives and directors have not been adding to their positions at current price levels. Dark pool activity registers at 9.3 out of 25, suggesting moderate but below-average off-exchange institutional buying interest. Congressional trading activity scores 12 out of 25, indicating some legislative portfolio exposure to the stock. The divergence between maximum institutional conviction and minimal insider buying creates a mixed signal profile, as 13F institutional filings confirm broad fund-level support while insiders have opted to reduce personal holdings during the trailing quarter.
Costco Wholesale Corporation Earnings Outlook
Costco Wholesale Corporation has delivered consecutive earnings beats across its three most recent reported quarters, according to company earnings reports. In the December 2025 quarter, the company posted earnings per share of $4.50 versus the consensus estimate of $4.36, a positive surprise of $0.14 or approximately 3.3%. The March 2026 quarter showed EPS of $4.58 against estimates of $4.55, a $0.03 beat. Most recently, the May 2026 quarter produced EPS of $4.93 compared to the $4.92 estimate, a marginal $0.01 upside surprise. Analyst estimates project next-quarter EPS of $6.53 for the September 2026 period, representing a substantial sequential increase from the prior quarter's result, per analyst estimates. The narrowing pattern of earnings surprises—from $0.14 to $0.03 to $0.01—indicates that analyst models have progressively tightened around Costco's actual performance, reducing the margin for upside surprise going forward.
Wall Street Analyst Ratings for COST

Across the five most recent analyst actions, three carry bullish designations—two Buy ratings and one Overweight—while two maintain Neutral positions. No analysts among recent coverage have issued bearish ratings such as Sell or Underweight.
