Why It's Moving

Amazon's $200B AI Spending Plan Triggers Sell-Off Despite Strong Analyst Outlook
- Amazon's $200B capex plan for 2026 (up from $125B in 2025) shocked markets, with roughly 80% earmarked for AI-related infrastructure including chips, robotics, and data center capacity, raising concerns about free cash flow turning negative this year
- AWS AI momentum remains a key growth catalyst, with Amazon confirming customers can continue using Anthropic's Claude on AWS for non-defense workloads while launching new healthcare automation tools and investing in capacity expansion
- Stock declined approximately 10% in after-hours trading following the announcement, though analysts maintain a 'Moderate Buy' consensus with a mean price target near $287, suggesting markets are pricing in near-term execution risk while longer-term AI demand drivers remain intact

Costco's Q2 Earnings Showcase Robust Sales Growth and Margin Expansion Amid Strong Membership Surge
- Membership fees rocketed 14% to $1.36 billion, fueled by new sign-ups, fee hikes, and high 92% renewal rates, bolstering the core recurring revenue model.
- Gross margins expanded with 11% profit growth outpacing 9% revenue rise, thanks to favorable gasoline and pharmacy sales plus sharp operating leverage.
- February sales surged 9.5% to $21.69 billion, signaling sustained momentum into the quarter while cash reserves swelled 40% to $17.4 billion.

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.
