Q2 2026 13F recap — stocks several institutions bought and sold together →Company overview
A membership-based warehouse-club retailer, with a loyal customer base renewing at over 90% annually and membership fees as a core revenue source. An efficient supply chain, scale-based low pricing, and a low-margin/high-turnover strategy are strengths. But its low-margin structure makes profitability sensitive to rising operating costs like labor and energy, and online competition is a medium-term challenge.
