Stock market today: Dow, S&P 500, Nasdaq edge higher as Nvidia's market cap hits $4T, Trump unveils more tariff letters

US equities, including the Dow (+0.1%), S&P 500 (+0.2%), and Nasdaq (+0.5%), edged higher Wednesday, propelled by Nvidia (NVDA) hitting a historic $4 trillion market capitalization, becoming the first company to reach this milestone. However, market gains were pared as President Trump unveiled further tariff notices, imposing 20-30% rates on additional countries and reaffirming an August 1 deadline, which also led to a retreat in US copper prices following his tariff threats. Investors are now focused on the upcoming Federal Reserve June meeting minutes for insights into policy and the debate surrounding trade uncertainty, with expectations for two rate cuts this year.

Analysis

US equity markets demonstrated a cautious upward trend, with the Dow Jones Industrial Average and S&P 500 posting modest gains of 0.1% and 0.2% respectively, while the tech-centric Nasdaq Composite rose 0.5%. Market performance reflects a clear divergence between the exceptional strength in the artificial intelligence sector and growing macroeconomic headwinds from trade policy. The primary catalyst for gains was Nvidia (NVDA), which reached a historic $4 trillion market capitalization, cementing its position as the world's most valuable company. However, broader market enthusiasm was curbed by President Trump's announcement of new tariff letters targeting multiple countries with rates of 20-30% and a reaffirmed August 1 deadline. This aggressive trade stance has created tangible market impact, evidenced by the retreat in US copper prices after a potential 50% tariff was mentioned. The uncertainty surrounding these tariffs has reportedly divided the Federal Reserve, making the upcoming June meeting minutes a focal point for investors who are currently pricing in two interest rate cuts this year.

Key Decisions for Investors

• Given Nvidia's market leadership and the Nasdaq's relative outperformance, investors should assess their concentration in mega-cap technology and AI-related equities, which are currently driving returns despite broader market risks.
• It is prudent to monitor companies with significant exposure to international trade and commodities like copper, as the approaching August 1 tariff deadline could introduce significant volatility and margin pressure.
• Closely watch the upcoming Federal Reserve minutes for any shifts in commentary regarding the impact of trade policy on the economy, as this could alter the market's current expectation of two interest rate cuts this year.
