Sector Trends Driving Performance

1. Consumer Staples and Health Care Drive Defensive Gains

Philip Morris International (+12.5%) and CVS Health (+11.8%) helped anchor sector performance as investors shifted toward defensive names amid rising tariff risks and declining consumer confidence. These sectors showed resilience in an otherwise volatile month.

2. Industrials and Utilities Show Relative Strength

Huntington Ingalls Industries (+16.9%) and Constellation Energy (+11.5%) led gains in Industrials and Utilities, respectively. With macro uncertainty increasing, capital flowed into infrastructure and regulated sectors often seen as late-cycle plays.

3. Select Tech and Communication Names Continue to Lead

NVIDIA (+9.8%), Meta Platforms (+10.2%), and Super Micro Computer (+10.9%) extended their leadership, supported by strong earnings momentum and AI-driven growth narratives. However, gains were more concentrated than broad-based, signaling selective risk-taking in tech.

4. Consumer Discretionary and Financials: Mixed Signals

Dollar General (+16.1%) and Starbucks (+9.9%) lifted consumer discretionary sentiment, but broader weakness persisted due to cautious guidance and margin pressure. Financials saw isolated strength from W.R. Berkley (+13.0%) and Berkshire Hathaway (+10.5%), but overall performance was uneven across the sector.

Strategic Implications for Advisors and Asset Managers

Portfolio Tilts

Defensive Allocation: Consider raising weights in Consumer Staples, Health Care, and Utilities to buffer against ongoing macro headwinds with S&P 500 stocks.
Focused Growth: Maintain selective exposure to AI and infrastructure names driving alpha, particularly in Information Technology and Industrials.

Tactical Adjustments

Use the Mutual Fund Screener to identify funds with recent overweight shifts toward defensives and dividend-rich names.
Apply Scenario & Stress Testing to simulate downside volatility and assess how defensive tilts impact drawdown profiles.

Sector Rotation & Risk Reassessment

Re-evaluate cyclical exposure in Consumer Discretionary and Financials based on earnings revisions and economic sentiment.
Use the Holdings Overlap Tool to identify overexposure to high-beta names or concentrated tech positions.
