Stock Market Today: S&P 500 Marks Best May in 30 Years as Wall Street Bets on Tariff Relief
By Amalya Dubrovsky, Karen Friar, and Allie Canal | Updated May 30, 2025
In a pivotal month for U.S. equities, the S&P 500 has recorded its best May performance in three decades, buoyed by investor optimism surrounding potential tariff relief between the United States and China. The month closed on a strong note despite early session volatility on Friday, highlighting resilience in the markets amid ongoing geopolitical and economic uncertainties.
Monthly Market Highlights
For May 2025, the S&P 500 rose by over 6%, marking its strongest monthly gain since November 2023 and the most impressive May performance since 1990. The Dow Jones Industrial Average (DJI) followed with a 4% climb for the month, while the tech-heavy Nasdaq Composite surged almost 10%, underscoring the sector’s dominance in driving market gains.
On Friday, the final trading day of May, equities rebounded from initial losses. The Nasdaq experienced a dip of 0.3% by the close, recovering from an earlier slide of more than 1.6%. The S&P 500 stayed near the flat line, and the Dow closed up modestly by 0.1%. All three major U.S. indexes ended both the week and the month in positive territory, reflecting a degree of investor confidence entering the summer trading period.
Market Drivers: Tariff Talks and Inflation Trends
Investors are navigating a complex mix of tariff-related developments and inflation signals that continue to influence market sentiment. The focus remains sharply on U.S.-China trade relations—especially amid reports of renewed tensions and regulatory actions.
Bloomberg reported that the Trump administration plans to expand technology restrictions on China, aiming to close loopholes exploited by subsidiaries of already-sanctioned firms. The proposed rules would require U.S. government licenses for transactions involving companies majority-owned by entities on the so-called Entity List.
This development follows President Trump’s recent social media criticism accusing China of violating the two countries’ trade deal less than three weeks after a tentative tariff detente was reached.
Scott Bessent, U.S. Treasury Secretary, described trade talks as "a bit stalled," emphasizing the need for direct communication between President Trump and Chinese President Xi Jinping. Bessent highlighted ongoing disputes over chip export restrictions and visa policies, which continue to complicate negotiations.
Furthermore, the tariff landscape is facing fresh uncertainty due to legal challenges. A U.S. appeals court recently paused a trade court decision that had blocked Trump’s global tariffs, granting the White House a deadline to respond. Concurrently, the administration is exploring alternative avenues to enforce tariffs, indicating the issue remains fluid.
On the inflation front, the latest Personal Consumption Expenditures (PCE) index showed continued cooling in April. The core PCE index, the Federal Reserve’s preferred inflation gauge, rose in line with market expectations on both a monthly and annual basis. This moderation in inflation provides some relief to investors wary of aggressive Fed policy tightening.
Tech Stocks and Market Outlook
The technology sector’s robust performance propelled much of the Nasdaq’s nearly 10% monthly surge, underscoring Wall Street’s continued belief in tech-driven growth despite regulatory headwinds. However, tech shares showed some volatility heading into the market close on Friday, reflecting the sensitive interplay between trade policy changes and investor sentiment.
As the markets enter June, Wall Street remains cautious but hopeful that easing trade tensions could pave the way for further gains. The dynamic mix of macroeconomic indicators, geopolitical developments, and corporate earnings will continue to shape the investment landscape.
