Today's Featured Research Reports

Amazon.com’s shares have outperformed the Zacks Internet - Commerce industry over the past year (+12.8% vs. +2.5%). The company’s international expansion and diversification across e-commerce, AWS cloud services, advertising and streaming create multiple revenue streams while reducing concentration risk. 

For 2Q’26, AMZN guided net sales of $194-$199 billion and operating income of $20-$24 billion. AI integration across operations enhances personalization, logistics and AWS offerings, strengthening competitive positioning. Shares have outperformed the industry in the past year. 

However, capital expenditure requirements for AI infrastructure and data centers strain financial resources and compress margins, with trailing-12-month free cash flow decreasing to $1.2 billion. The company’s expanding debt burden reduces financial flexibility amid rising interest rates. Intensifying competition from Walmart, Microsoft Azure, and Google Cloud is an overhang.

Shares of Walmart have outperformed the Zacks Retail - Supermarkets industry over the past year (+17% vs. +12.9%). The company remains well positioned due to its scale, value proposition and expanding omnichannel ecosystem. The company’s store network supports fast fulfillment, convenient pickup and delivery, and stronger digital engagement. 

Marketplace, advertising and membership are becoming more important profit drivers, helping diversify earnings beyond traditional retail and improve the business mix. Investments in automation and AI should enhance customer experience, efficiency and long-term productivity. 

Strong traffic, broad assortment and price leadership also create opportunities to expand higher-margin services over time. While fuel costs, currency movements, policy uncertainty and elevated investments may affect near-term profitability, Walmart’s focus on execution, digital expansion and ecosystem growth supports a favorable long-term outlook.

American Express’ shares have outperformed the Zacks Financial - Miscellaneous Services industry over the past year (+13.4% vs. -22%). The company is benefiting from strong spending growth, particularly from Millennials and Gen Z, supported by experience-driven rewards, travel and dining platforms, and expanding digital capabilities. Strategic acquisitions and partnerships across travel, lifestyle, and small-business ecosystems further strengthen engagement and transaction volumes. 

AI Investments, digital payments, and B2B solutions are also enhancing long-term growth prospects. It returned $2.3 billion to shareholders in Q1 2026 through dividends and buybacks. AXP has outperformed its industry over the past year. 

However, rising expense intensity, elevated credit-loss provisions amid weakening consumer credit trends, and relatively high leverage could pressure margins and earnings stability if macro conditions remain challenging. We reiterate a Neutral stance on the stock.

Shares of Natural Grocers by Vitamin Cottage have outperformed the Zacks Food - Natural Foods Products industry over the past six months (+38.5% vs. +23.2%). This microcap company with a market capitalization of $765.18 million is supported by resilient operating performance, with positive comparable sales growth, rising loyalty program penetration and continued earnings growth despite a cautious consumer environment. 

Natural Grocers by Vitamin Cottage offers a compelling long-term growth story through disciplined store expansion, a flexible small-format model and a targeted 4-5% annual unit growth rate. An expanding portfolio of more than 900 exclusive private-label products, ERP-driven operational efficiencies and robust cash generation strengthen its competitive position and provide financial flexibility to fund growth initiatives and dividends.

However, key risks include softer consumer spending on premium organic products, rising technology and expansion costs, supply-chain and organic sourcing constraints, and intensifying competition from larger retailers. The stock trades at 0.56X trailing 12-month EV/sales.

Ampco-Pittsburgh’s shares have outperformed the Zacks Metal Products - Procurement and Fabrication industry over the past six months (+39.8% vs. -2.3%). This microcap company with a market capitalization of $162.21 million has its investment thesis supported by its shift toward higher-value infrastructure markets, with ALP benefiting from sustained demand across nuclear energy, defense, power generation and mission-critical industrial applications. 

Portfolio rationalization and footprint optimization should improve utilization, margins and earnings quality, while favorable tariff dynamics, reshoring trends and industry consolidation create market share opportunities. 

Yet execution remains critical as AP must improve profitability in its core FCEP business and convert backlog into sustainable cash flow. Elevated leverage and asbestos liabilities remain overhangs. The valuation suggests investors continue to discount execution and balance-sheet risks despite improving fundamentals, offering upside if operational recovery, margin expansion and deleveraging progress as expected.
