COST Costco
A widening scale moat and superb culture, but the price assumes implausible decade-long growth.
The business
Costco operates membership warehouses that sell a limited assortment of goods at very low markups and high inventory turnover. Merchandise generates enormous purchasing scale, while recurring membership fees provide most operating profit and reinforce customer loyalty.

Moat & management
| Moat | wide moat |
| Source | scale |
| Trajectory | widening |
| Management | excellent |
Its growing membership base, purchasing volume, rapid inventory turnover, and trusted low-price reputation form a self-reinforcing cost advantage. Few competitors can match Costco's prices while accepting similarly thin merchandise margins.
Management prioritizes member value, disciplined warehouse expansion, sensible leverage, and occasional special dividends rather than empire-building or dilution. This restraint strengthens the franchise even when it suppresses near-term margins.
