S&P rises amid tariff chatter

The S&P 500 has climbed back to record territory even as tariff policy stays unsettled and investors keep recalculating what that means for profits. (cnbc.com) On Friday, April 17, the index rose 1.2% to 7,126.06, its first close above 7,100. The Nasdaq Composite gained 1.52% to 24,468.48, its 13th straight advance, and the Dow Jones Industrial Average added 868.71 points. (cnbc.com) The S&P 500 covers about 500 large U.S. companies and roughly 80% of available U.S. stock market value, so moves in the index are often read as a broad verdict on corporate America. By April 17, its forward price-to-earnings ratio was about 20.68, according to data sourced from Standard & Poor’s. (spglobal.com) (en.macromicro.me) Tariffs matter to stocks because they can raise companies’ costs, squeeze profit margins, and force analysts to cut earnings estimates. When investors think those costs may be reversed, or refunded, they often raise what they are willing to pay for each dollar of future earnings. (spglobal.com) (thomsonreuters.com) A major turning point came on February 20, 2026, when the U.S. Supreme Court ruled 6-3 that the International Emergency Economic Powers Act did not authorize the broad tariffs at issue. Penn Wharton estimated that more than $175 billion in tariff collections could be subject to refunds after that decision. (usnews.com) (budgetmodel.wharton.upenn.edu) Yale’s Budget Lab put the potential refunds in the same range, estimating that about $165 billion in unlawfully collected duties may be returned to importers and consumers. The group also said tariffs had raised roughly $214.7 billion above the 2022-2024 average, with $175.5 billion collected during 2025. (budgetlab.yale.edu) That has left traders balancing two opposing forces at once: tariff refunds can boost cash flow for import-heavy companies, while ongoing legal fights and new tariff threats can still hit supply chains and pricing. Thomson Reuters said the court ruling created “major uncertainty” around refunds, and trade lawyers are still tracking separate cases over other tariff authorities. (thomsonreuters.com) (tradecomplianceresourcehub.com) Earnings season is now testing those assumptions in real time. FactSet said on April 17 that the first quarter reporting season had started stronger than expected, with both the share of companies beating earnings forecasts and the size of those beats running above recent averages. (insight.factset.com) The market’s rebound has not been driven by tariffs alone. CNBC reported that Friday’s rally also followed easing geopolitical stress in the Middle East, a drop in oil prices, and a broad advance that lifted small-cap stocks as well as big technology names. (cnbc.com) For now, the index is trading as if lower energy costs, solid earnings, and possible tariff relief can outweigh the next round of trade headlines. The next few weeks of company guidance will show whether that optimism holds up. (cnbc.com) (insight.factset.com)
