Stock market today: Dow, S&P 500, Nasdaq fall with focus on Trump Iran decision, Fed rate cuts, China chip tensions

US stocks experienced a mixed trading day Friday, with the S&P 500 and Nasdaq closing lower by 0.1% and 0.4% respectively, while the Dow Jones Industrial Average rose 0.3%, as investors weighed several factors including President Trump's impending decision on Iran, dovish comments from Fed Governor Waller hinting at potential July rate cuts, and concerns over potential restrictions on semiconductor exports to China, which negatively impacted chip stocks like Nvidia (NVDA), down approximately 1.1%.

Analysis

US equity markets exhibited a divergent performance, with the Dow Jones Industrial Average rising 0.3% while the S&P 500 and Nasdaq Composite fell 0.1% and 0.4% respectively, reflecting a market caught between conflicting macroeconomic signals. The primary headwinds were geopolitical uncertainty and sector-specific trade tensions. President Trump's self-imposed two-week deadline on deciding whether to engage in military action with Iran has created a temporary window for diplomacy, which caused oil prices to recede, but maintains a high level of caution. Simultaneously, the technology sector, particularly semiconductors, faced direct pressure following a report that the US may revoke waivers allowing access to American technology in China, causing shares of Nvidia (NVDA) to decline approximately 1.1%. Counterbalancing these risks were dovish comments from Fed Governor Chris Waller, who floated the possibility of a July interest rate cut, citing tame inflation data. This provided a positive catalyst, though it contrasts with Fed Chair Powell's more patient stance and market pricing that, according to CME Group, still favors a September cut.

Key Decisions for Investors

• Investors should closely monitor geopolitical developments regarding the US-Iran situation over the next two weeks, as any escalation or de-escalation will be a significant driver of short-term market volatility.
• Given the specific threat of revoking technology waivers for China, positions in the semiconductor sector, including names like Nvidia, warrant re-evaluation due to heightened policy risk.
• Note the dovish signal from Fed Governor Waller, but weigh it against the consensus view of a later rate cut; any shift in market expectations toward a July cut could serve as a near-term bullish catalyst for the broader market.
