Why It’s Moving

Amazon’s latest AWS surge is keeping the bull case alive as analysts lean more positive.
- AWS reaccelerated sharply in Amazon’s latest quarter, with cloud revenue rising 36.8% year over year to $42.2 billion and operating income climbing 63.6%, reinforcing the idea that AI demand is now showing up in the core business.
- Amazon also delivered a broad earnings beat, with revenue of $200.61 billion and adjusted EPS of $1.97 topping expectations, which helped ease concerns that heavy spending was crowding out profitability.
- Analysts turned more constructive after the results, with several firms lifting ratings and highlighting AWS capacity, AI monetization, and margin strength as the main reasons sentiment improved.

Costco stays on investors’ radar as analysts lean bullish, but valuation keeps the stock in check.
- Analyst sentiment remains constructive, with Costco still drawing a broad Moderate Buy view from Wall Street, which is helping support the stock after a strong 2026 run.
- Recent coverage points to expectations for continued earnings growth, suggesting investors are focused on whether Costco can keep translating membership strength and traffic into higher profits.
- The main overhang is valuation: the shares have already rallied sharply, so even positive analyst commentary has been met with questions about how much upside is left without another clear growth catalyst.

Investment Analysis

Amazon
AMZN
Pros
- Amazon's e-commerce platform is supported by a highly efficient logistics network, enabling consistently low prices and strong customer retention.
- Amazon Web Services remains a dominant cloud provider, generating substantial and growing operating income for the company.
- Amazon's stock is currently trading below its estimated intrinsic value according to discounted cash flow models, suggesting potential upside.
Considerations
- Amazon faces intense competition in both e-commerce and cloud services, which could pressure margins and growth rates.
- The company's profitability is sensitive to macroeconomic conditions and consumer spending trends, making it somewhat cyclical.
- Amazon's valuation, while below intrinsic value, is still elevated compared to some peers, increasing downside risk if growth slows.

Costco
COST
Pros
- Costco's membership model delivers high customer retention and recurring revenue, contributing to stable earnings growth.
- Recent membership fee increases are expected to boost earnings, with most of the benefit materialising in 2025 and 2026.
- Costco maintains a strong balance sheet and consistent cash flow, supporting its ability to invest and return capital to shareholders.
Considerations
- Costco's stock is trading at a premium forward price-to-earnings ratio, indicating it may be overvalued relative to fundamentals.
- The company's growth is largely dependent on physical store expansion, which can be capital-intensive and slower than digital models.
- Costco's business is exposed to inflation and supply chain disruptions, which could affect margins and operational efficiency.
