Commentary: Trump’s trade war is hurting most sectors of the economy

A Yahoo Finance analysis indicates that President Trump's tariffs are significantly impacting U.S. corporate profitability and forcing price increases across seven of the eleven S&P 500 sectors, encompassing 68% of companies. Major firms including General Motors, Ford, Apple, and Caterpillar have reported substantial tariff-related costs and profit reductions, with overall monthly tariff burdens escalating from $7 billion to $30 billion. While some domestic sectors and companies, like Nucor, have seen benefits, and the broader market has risen due to factors such as the AI boom or large-cap resilience, U.S. stocks are notably underperforming global equities, suggesting tariffs represent a considerable economic drag that will likely be further revealed in future earnings.

Analysis

Analysis of second-quarter earnings calls reveals that U.S. tariff policies are causing significant, quantifiable financial damage across a broad swath of the S&P 500. Seven of the eleven market sectors, representing 68% of index constituents, are reporting adverse effects, primarily in the form of margin compression and forced price increases. Specific material impacts include a cited $1.1 billion profit hit for General Motors, a forecasted $2 billion annual reduction for Ford, and up to a $1.5 billion drain for Caterpillar. Technology firms such as Apple incurred $800 million in tariff costs, while export restrictions cost Nvidia and AMD $5.5 billion and $800 million in sales, respectively. This widespread pressure, which has elevated monthly import tax costs from $7 billion to approximately $30 billion, contrasts with the relative insulation of domestic-focused sectors like Financials (XLF) and Utilities (XLU). Despite the rising headline stock market index, driven partly by the AI boom, a key divergence is apparent: U.S. stocks have underperformed global ex-U.S. equities by 10 percentage points this year (10% vs. 20% growth), suggesting trade friction is a tangible drag on relative performance. While a few companies like steelmaker Nucor (NUE) benefit from reduced import competition, the overall evidence points to a net negative economic impact that has not yet been fully priced into all US equities.

Key Decisions for Investors

• Investors should consider re-weighting portfolios towards sectors insulated from international trade tariffs, such as Financials (XLF), Utilities (XLU), Real Estate (XLRE), and Communication Services (XLC), while being cautious of exposure to Industrials (XLI), Consumer Discretionary (XLY), and Materials (XLB).
• Scrutinize holdings in companies that have explicitly quantified large negative impacts from tariffs and export controls, including GM, F, CAT, NVDA, and AMD, as their profitability and margins are under direct pressure.
• Consider increasing allocation to non-U.S. equities, as the 10% underperformance of U.S. stocks relative to global markets suggests a potential risk premium associated with U.S. trade policy.
• Closely monitor upcoming corporate earnings for commentary on pricing power and margin sustainability, as a company's ability to pass on higher tariff-related costs without destroying demand will be a critical determinant of future performance.
