Costco Wholesale Valuation: P/E Multiple vs. Retail Peers

### Tape / Session Read Costco Wholesale (NASDAQ: COST) commands a P/E multiple of 47.9, sitting above large-cap peers such as Walmart ($WMT+WL) at 42.8 and Amazon ($AMZN+WL) at 20.9. Data through absolute calendar dates ending October 2026 shows Costco's revenue grew 10.1% over its latest four fiscal quarters, while operating margins stood at 3.9% compared to Amazon's 12.1% and Walmart's 4.4%.

### Why This Lane Matters Retail sector valuation relies heavily on membership fee stability and steady renewal metrics rather than product margins alone. In the U.S. and Canada, 92.3% of members renewed at the end of fiscal Q4, providing recurring cash flow that underpins higher equity pricing multiples across consumer staples.

### Money Play - If $COST+WL maintains its premium valuation relative to broadline retailers, watch membership fee growth and renewal rates as key indicators of core cash generation. - If retail sector margin expansion continues to favor operators with higher operating income proportions, traders can compare $WMT+WL and $AMZN+WL multiples against $COST+WL.
