Overview
Costco is a membership-based warehouse retailer. It sells a limited selection of products in bulk at low margins, earning much of its profit from highly recurring membership fees rather than merchandise markup.
Its scale, buying power, and loyal members create a durable flywheel: low prices drive renewals, and renewals fund low prices. The key debate is whether a premium valuation is justified for such a high-quality but slow-growing model.

| Peter Lynch | Growth vs. price (PEG) | Does steady membership growth justify a premium multiple? |
| Howard Marks | Where are we in the cycle? | How sensitive is the model to a consumer slowdown? |
| Benjamin Graham | Margin of safety | At this multiple, what protection do I have if growth slows? |
