Costco Wholesale Corporation (COST) Insider, 13F Hedge Fund & Politician Buy/Sell Thermometer

COST scores 81 out of 100, grading A- under the verdict label "Roarable Buy — Superior Risk/Reward." The five pillars are:

• Fundamental Cash Engine: 20 / 20 (ROIC 42.4%; FCF yield 2.09%). This is the maximum pillar score, indicating strong capital efficiency in the source's framework. The modest 2.09% FCF yield, however, signals that much of the cash-generating strength is already reflected in the share price.
• Whale 13F Flow: 16 / 20 (institutional accumulation and options positioning). Solid institutional support, with a clear but not maximal score.
• Insider Conviction: 13 / 20 (SEC Form 4 and Congressional PTR cluster flow). Mixed insider activity is reflected in a mid-range score; the holders section shows both insider sales and institutional/political purchases.
• Macro Regime Fit: 12 / 20 (Beta 0.73; sector sensitivity). The lowest pillar, though a beta below 1.0 suggests lower price volatility relative to the market. The score indicates that sector sensitivity is a consideration.
• Forensic Balance Sheet: 20 / 20 (Altman Z 9.38; Piotroski F 6/9; Debt/Equity 0.17). Maximum score on balance-sheet strength. Note that the Piotroski F-Score of 6 of 9 is solid but not perfect.

For a prospective investor, the upside case rests on the cash-generation and balance-sheet pillars, both at maximum. The valuation tradeoff is material: P/E (TTM) of 48.6 and EV/EBITDA of 31.4 are elevated, and the 2.09% FCF yield means the investor is paying a premium for durability. The score is a framework output from the source and is not a recommendation.

Costco Wholesale Corporation is classified in the Consumer Staples sector, Membership Warehouse Clubs & Kirkland Private Label industry, and trades on NASDAQ.. It monetizes recurring Gold Star and Executive membership fees and caps gross merchandise markups near 14–15%, with an industry-benchmark renewal rate of approximately 93% in North America. Membership fee revenue is a $4.8B+ high-margin fee pool, and Kirkland Signature represents approximately 33% of sales.

Per the market data, gross margin is 12.8%, operating margin 3.9%, and net margin 3.0%. ROIC stands at 42.4%. Per the forensic metrics in the RQD rating, the Altman Z-Score is 9.38, the Piotroski F-Score is 6 of 9, and Debt/Equity is 0.17. Reported cash of $20.21B against debt of $6.16B in the latest period reflects a conservative balance-sheet posture.

• 🐂 Primary Bull Case: Perfect 20/20 scores on cash-engine and balance-sheet pillars (ROIC 42.4%, Altman Z 9.38) alongside a STEALTH WHALE ACCUMULATION signal of severity 87 and 17.83% implied upside to consensus target. With Fundamental Cash Engine at 20/20 (ROIC 42.4%, FCF yield 2.09%) and Institutional Whale Flow at 15/20, sustained execution supports upside toward the top of the $844.06 – $1,096.50 52-week range.
• 🐻 Primary Bear Case: Valuation sits at 48.6x trailing P/E and 31.4x EV/EBITDA with only a 2.09% FCF yield, and the Macro Regime Fit pillar scores just 12/20 amid a RED risk-watch item calling for no upside from here. Investors must weigh 48.6x trailing P/E and 31.4x EV/EBITDA against 3.9% operating margins and a 0.73 macro beta if sector demand softens.

(Consumer Staples; Membership Warehouse Clubs & Kirkland Private Label):

• Customers: Visa (V) is listed as a critical customer relationship tied to co-branded Costco Anywhere cardholders, with 76M+ paid household and business members (~93% US/Canada renewal) and a revenue exposure figure of 98%. Because membership fees are the high-margin pool, any shift in card or renewal economics would ripple through margin.
• Suppliers: Procter & Gamble (PG) is a critical supplier for national brands and Kirkland Signature bulk manufacturing, with a revenue exposure figure of 48%. Refined fuel wholesale suppliers (XOM) are rated high-criticality for the roughly 12% of total revenue tied to gasoline stations. Investors should watch input-cost pass-through, since the source ties Kirkland and fuel to meaningful revenue shares.
• Competitors: Walmart/Sam's Club (WMT) is rated critical at 85% exposure, Amazon (AMZN) high at 55% (Prime, Whole Foods), and BJ's Wholesale (BJ) moderate at 22%. Competitive pressure on membership renewal and grocery pricing is the principal second-order risk the graph highlights.

The graph's butterfly_links array is empty, so no explicit cross-company linkages are documented beyond the node relationships above.

• Key Question #1: The financials table shows FCF as N/A for Q4 2026 and Q3 2026. What is the trailing free-cash-flow figure, and how does it reconcile with the stated 2.09% FCF yield?
• Key Question #2: The RQD rating assigns Macro Regime Fit 12 of 20 and cites "sector sensitivity" without specifying the sensitivity measure. Which macro variables drive that score?
• Key Question #3: The Butterfly graph lists a 98% revenue exposure to Visa-linked membership, yet the membership fee dollar figure is given only as "$4.8B+." What is the precise fee revenue for the most recent reported period?
