Membership economics are the most underrated moat in retail

The stock traded at 910.51 this morning, -0.32% on the session. I have written about this business admiringly for years, which makes it exactly the one I need to be most careful about.

The model, honestly stated

A membership retailer is two businesses wearing one coat. There is a low-margin goods operation whose job is to be so obviously good value that leaving feels stupid. And there is a subscription business with very high incremental margins that the goods operation exists to justify.

The second one is where the economics live. The first one is the moat protecting it.

This is why gross margin analysis on these companies so often misses. You are looking at the cost of maintaining the moat and calling it the business.

What actually matters

• Renewal rate, and specifically its stability rather than its level. A high rate that is drifting is worse than a slightly lower one that has held for a decade.
• Membership growth split between new and reactivated, because those are different customers with different lifetime value.
• Traffic against basket size. Rising baskets on falling traffic is a warning that reads as strength for two or three quarters.

Why I am not buying

None of the above has deteriorated. That is not the issue. The issue is that the quality is extremely well understood, and the price reflects a market that also knows it.

Recognising a wonderful business is easy and worth very little. Almost everyone has already done it.

I do not have an edge in telling you that a famously good retailer is a famously good retailer. I might have an edge in being willing to wait for a price where being right pays properly.

What would change it

A multiple reset on something that does not damage the model. Retail sells off periodically for reasons that have nothing to do with the specific business, and the membership names get caught in it. That is the moment to be ready, and being ready means having done this work in advance rather than during.

Until then I am watching renewal disclosure each quarter and doing nothing, which is most of the job.
