AI Summary

7.0
Positive

Costco remains an exceptional, cash-generative compounder, but the stock is now priced for near-flawless execution, so the key takeaway is that upside depends on sustained double-digit sales growth, improving membership quality, and avoiding margin pressure from tariffs/logistics—otherwise the premium multiple is vulnerable to compression.
