Costco Wholesale Corporation Valuation Analysis
Costco carries a trailing price-to-earnings ratio of 47.3, a substantial premium relative to the broader Consumer Defensive sector, per SID market data. The stock's price-to-book ratio stands at approximately 12.96, reflecting the market's willingness to pay a significant markup over the company's net asset value. The PEG ratio registers at negative 2.13, a figure that warrants context as it may reflect anomalies in forward growth estimate calculations rather than an anticipated earnings decline, according to SEC filings and consensus data. Costco's dividend yield sits at 0.57%, a relatively modest payout consistent with the company's historical emphasis on reinvestment and periodic special dividends. At a market capitalization of approximately $392 billion, Costco commands one of the highest valuations among warehouse retailers. The elevated earnings multiple suggests the market is pricing in sustained membership growth and operational efficiency gains over the medium term.
Smart Money Activity for COST
Costco's composite smart money score stands at 39 out of 100, generating a bearish signal according to SID market data. The institutional component scores a perfect 25 out of 25, reflecting robust and sustained institutional ownership, while the insider score registers at 0.0 out of 25, the lowest possible reading. Over the past 90 days, SEC Form 4 filings reveal 20 insider transactions, comprising just 3 purchases against 17 sales, a ratio that indicates notable net selling by company officers and directors. The dark pool activity score of 9.5 out of 25 suggests moderate but below-average institutional block trading interest, per 13F institutional filings. Congressional trading activity scored 4.9 out of 25, indicating limited legislative buying interest at current price levels. The divergence between maximum institutional conviction and minimal insider confidence represents a notable disconnect that characterizes the current positioning landscape for Costco shares among sophisticated market participants tracking Form 4 disclosures.
Costco Wholesale Corporation Earnings Outlook
Costco has delivered four consecutive quarters of positive earnings surprises, according to company earnings reports. The most recent quarter posted earnings per share of $6.75 against a consensus estimate of $6.52, representing a $0.23 beat and the largest outperformance in the reported period.

Across the four reported periods, Costco's EPS ranged from $4.50 to $6.75, demonstrating the seasonal pattern typical of its fiscal calendar, with the September-ending quarter consistently generating the highest profitability. The sequential improvement from $4.50 to $4.58 to $4.93 to $6.75 across the four quarters reflects both seasonal dynamics and underlying business expansion. The consistent pattern of meeting or exceeding estimates underscores management's track record of operational execution.
Wall Street Analyst Ratings for COST
Recent Wall Street analyst activity for Costco skews predominantly positive, per SID consensus data. In October 2026, CICC initiated coverage with an Outperform rating, adding a new bullish voice to the coverage universe. Tigress Financial maintained its Buy rating in the same month, while Deutsche Bank and Argus Research both reiterated Buy recommendations in late September, according to Wall Street analyst reports.
