Jim Cramer's top 10 things to watch in the stock market Tuesday

A federal appeals court ruling challenging the legality of President Trump's tariffs introduces significant market uncertainty, potentially leading to billions in refunds and worsening the U.S. fiscal outlook. Amidst this, corporate activity includes Elliott Management's disclosed $4 billion stake in PepsiCo, which boosted shares, and Kraft Heinz's planned split into two companies. Additionally, positive analyst sentiment was observed for several firms, with upgrades for Broadcom, Zscaler, and Corning, and Walmart added to Goldman Sachs' conviction buy list, while Starbucks reported record sales.

Analysis

The market is facing renewed macroeconomic uncertainty following a federal appeals court ruling that President Trump's tariffs may be unconstitutional, a development that could lead to a Supreme Court challenge and require the U.S. to refund billions, potentially worsening the nation's fiscal position and elevating bond yields. Against this backdrop, several company-specific catalysts are driving individual stock performance. Activist firm Elliott Management has taken a substantial $4 billion stake in PepsiCo, fueling a more than 4% rise in its shares on expectations of strategic changes. In corporate restructuring, Kraft Heinz is proceeding with a plan to split into two separate entities, though the market reaction has been muted as the move was previously rumored. Positive analyst actions are highlighting key sector themes: Melius Research raised its price target on Broadcom to $335, citing its AI leadership role as a reason to buy any weakness, while UBS upgraded Corning to buy with an $84 target, betting on AI-driven demand for fiber optics. Similarly, Morgan Stanley upgraded Zscaler to overweight with a $320 target based on the cybersecurity industry's shift to platformization. In retail, Walmart was added to Goldman Sachs' conviction buy list on its potential to gain market share in a tariff environment, while Starbucks reported a 'record-breaking sales week' in the U.S., signaling resilient consumer spending on affordable luxuries.

Key Decisions for Investors

• The $4 billion activist stake in PepsiCo by Elliott Management signals a strong potential for value-unlocking initiatives, warranting a review of the stock for further upside driven by strategic or operational changes.
• Analyst upgrades for Broadcom and Corning underscore the durable AI infrastructure theme; investors should consider any market-induced weakness in these names as a strategic buying opportunity, given their perceived scarcity value.
• The federal court ruling on tariffs introduces significant macro risk and potential market volatility; it is prudent to monitor developments in this case and its effect on bond yields, especially entering a historically weak month for equities.
• Given Walmart's addition to Goldman's conviction buy list and Starbucks' record sales, a barbell strategy in consumer stocks could be effective, balancing exposure between value-oriented retailers and strong premium brands demonstrating demand resilience.
