Stock Market Update: S&P 500 Posts Best May in 30 Years Amid Optimism Over Tariff Relief
By Smart Money Mindset Staff
May 31, 2025 – U.S. stock markets wrapped up a volatile but ultimately strong May, with the S&P 500 marking its best monthly performance since 1990. Investor optimism around potential tariff relief and easing inflationary pressures propelled major indices higher over the month, as Wall Street bets on a thaw in U.S.-China trade tensions.
S&P 500 Logs Over 6% Gain in May
The S&P 500 (^GSPC) rose more than 6% for the month, its best May since 1990 and the strongest monthly showing since November 2023. The technology-heavy Nasdaq Composite (^IXIC) outperformed, surging nearly 10%, buoyed by strength across major tech stocks. The Dow Jones Industrial Average (^DJI) added approximately 4% for the period, rounding out a broad-based rally.
On the final trading day of the month, the Nasdaq experienced a modest dip of 0.3% after earlier falling more than 1.6% during the session. Meanwhile, the S&P 500 hovered close to unchanged levels, and the Dow inched up 0.1%, as investors digested ongoing geopolitical and economic news.
Trade Talks Resume Amid Continued Challenges
Market participants remain fixated on U.S.-China trade relations, which have shown signs of strain even after recent tariff détente efforts. Bloomberg reported Friday that the Trump administration plans to expand tech restrictions targeting Chinese subsidiaries of firms already on the U.S. Entity List, aiming to close loopholes circumventing existing curbs. These proposed measures would require U.S. government licenses for transactions with majority-owned entities of sanctioned companies.
This development follows sharp rhetoric from President Trump accusing China of violating the trade deal within weeks of the agreement. Treasury Secretary Scott Bessent also characterized trade talks as “a bit stalled,” emphasizing the need for direct dialogue between Presidents Trump and Xi Jinping to progress on contentious issues such as semiconductor export controls and visa policies.
Adding to the uncertainty, a U.S. appeals court recently paused a trade court order blocking President Trump’s global tariffs, giving the White House additional time to respond and explore alternative tariff implementation strategies.
Inflation Indicators Point to Cooling Price Pressures
Amid the trade-related volatility, inflation data provided some reassurance to investors. The Personal Consumption Expenditures (PCE) index, the Federal Reserve’s preferred inflation gauge, showed continued cooling in April. The core PCE index rose modestly in line with expectations on both a monthly and annual basis, suggesting inflation pressures may be stabilizing, which is favorable for market sentiment.
Looking Ahead
While May’s strong performance culminated in gains for all major U.S. equity indices, the path forward remains subject to shifts in trade policies and inflation trends. Investors will be closely monitoring the evolving U.S.-China negotiations and forthcoming economic data for guidance on the durability of the market rally.
Key Index Performance for May 2025:
- S&P 500 (^GSPC): +6%
- Nasdaq Composite (^IXIC): +9.8%
- Dow Jones Industrial Average (^DJI): +4%
