Costco is the Only "Safety Play" with a 90% Renewal Tailwind

"With members sticking around for the excellent value proposition as well as the $1.50 hot dog combo, it's clear that Costco has pretty much perfected the in-store experience at this point. The 90% renewal rate might just be the floor as the firm opens new stores across the globe while doubling down on e-commerce, perhaps there's room to bump up that renewal rate further."

"As a main beneficiary of 'invisible AI,' or AI that works hard behind the curtains, there's potential for the well-run retail juggernaut to pass even more savings onto its members. Given Costco's member-first approach, I certainly wouldn't bet against the firm as it goes out of its way to give more back to members, even if it means foregoing a few basis points of margin."

"After all, there aren't many steady defensive stocks that are also capable of steady growth. Any way you look at it, all things seem to suggest margins and membership renewal rates are poised to go up over time."

Costco has gained over 16% in 2026 but faces resistance near $1,000 per share with a valuation of 51x trailing P/E. The company maintains exceptional 90% global membership renewal rates driven by its superior in-store experience and value proposition, including the iconic $1.50 hot dog combo. Costco is expanding internationally and investing in e-commerce while leveraging AI technology to enhance operations and pass savings to members. The company's member-first philosophy prioritizes customer value over margin expansion. With new store openings, AI implementation, and potential for higher renewal rates, Costco demonstrates characteristics of both steady defensive and growth stocks, justifying its premium valuation despite intense retail competition.
