Amazon is now trading at a trailing price-to-earnings ratio of about 20, roughly a value-stock multiple, while Costco sits near 50 times earnings, a premium usually reserved for faster-growing companies. The gap matters because it captures a major investor split: Amazon’s AI-driven cloud engine is losing some of its old valuation gloss, while Costco’s defensive, fee-rich model is drawing a scarcity premium as markets look for shelter.
Amazon Valuation Lags Costco on AI and Cloud Concerns
For Amazon, the discount reflects concerns that the cloud unit driving more than 60% of operating income is facing tougher competition from Alphabet and Microsoft, even as the company pours money into artificial intelligence. That combination has left investors wary that current spending may take longer to pay off, especially after Amazon shares have swung between a low of $210.11 in February and a recent close of $259.30, still below its 50-day moving average of $253.95 after a brief rebound.
Sentiment Indicators
Costco, by contrast, has benefited from the market’s hunger for businesses seen as resilient if growth slows or AI enthusiasm cools. The warehouse club’s shares closed at $1,053.56 on Nov. 6, above both its 50-day average of $951.19 and its 200-day average of $969.93, and near the upper end of their recent trading band, underscoring sustained demand even after a sharp run-up from roughly $918 in mid-September.
The reversal is striking because Amazon has long been treated like the superior growth stock and Costco like a steady but less exciting retailer. Now Amazon’s retail and cloud mix is being valued more cautiously just as Costco’s low-price, membership-based model is being rewarded for predictability, margin stability and perceived insulation from a weaker consumer backdrop.
Investor positioning also fits the broader mood. Adalytica’s consumer-spending sentiment gauge is in “Fear,” while the retail-goods spending gauge remains in “Extreme Greed,” suggesting money is still flowing toward names tied to essential purchases and away from more cyclical bets. For Amazon shareholders, the key question is whether the current multiple already prices in the cloud slowdown and AI spending surge; for Costco investors, the risk is that a premium near 50 times earnings leaves little room for disappointment.
The next catalyst is whether Amazon can show that AWS growth is stabilizing and that AI investment is translating into faster sales or better margins. If not, the valuation discount could persist, even as Costco’s rich multiple leaves it more exposed to any loss of investor faith in defensive retail.
