No material news briefings were available for Costco Wholesale Corporation (COST) in the 30 days preceding this report's generation date of 2026-07-27. The principal driver of this report is a set of material institutional position changes identified in recent 13F filings, as detailed in the holdings section below [Brief - 2026-07-19].
Costco's trailing twelve-month revenue stood at $293.6 billion as of the most recent filing date, reflecting year-over-year revenue growth of 11.6%. Net income for the same period was $8.84 billion, with a net margin of 3.01% and an operating margin of 3.82%. Gross margin was recorded at 5.61%, consistent with Costco's warehouse membership model. EPS grew 15.2% year-over-year. The company held $18.95 billion in cash against total debt of $5.71 billion, and its market capitalisation stood at approximately $414.7 billion. The trailing P/E ratio was 47.03 [SEC 10-Q - COST - 2026-05-10].
Insider activity in July 2026 recorded one transaction with a net value of zero, presenting a mixed directional signal for the period [SEC Form 4 - COST - 2026-07]. On the institutional side, four notable managers opened new positions in COST during the most recent reporting period: Citadel (Ken Griffin), AQR Capital (Cliff Asness), Millennium (Izzy Englander), and Bridgewater (Ray Dalio) each initiated holdings in the company [SEC 13F - Citadel - Q2 2026] [SEC 13F - AQR Capital - Q2 2026] [SEC 13F - Millennium - Q2 2026] [SEC 13F - Bridgewater - Q2 2026]. The simultaneous entry of four distinct major institutional managers constitutes the material change that triggered this report.
The prevailing macroeconomic backdrop shows the 10-year US Treasury yield at 4.71% and the 2-year yield at 4.37%, producing a normal yield curve with a spread of 34 basis points [FRED DGS10] [FRED DGS2]. This rate environment represents the broader context within which Costco's fundamentals and ownership changes are recorded.
