The U.S. stock market closed higher on Thursday, with the S&P 500, Nasdaq Composite, and Dow Jones all recording gains. The S&P 500 rose 43.27 points (0.58%) to 7,563.63, the Nasdaq Composite gained 242.74 points (0.91%) to 26,917.47, and the Dow Jones added 24.69 points (0.05%) to 50,668.97. The broad-based rally was driven by optimism around a potential Iran ceasefire extension, which eased concerns about geopolitical tensions. Additionally, strong earnings reports from tech giants like Snowflake and Salesforce, as well as a positive monthly inflation report, contributed to the positive sentiment. The market's performance was uneven, with energy stocks underperforming due to a slight pullback in oil prices. Bond yields also eased, reflecting investor optimism and reduced risk appetite.

The overall tone of the market session was risk-on, with investors favoring equities over fixed income. The rally in the S&P 500 and Nasdaq Composite marked new all-time highs, driven by a tech-led recovery. The Dow Jones, however, showed more volatility, with a slight dip in the afternoon session. The market's performance was also influenced by a mixed bag of economic data, including a softer-than-expected monthly inflation report and a rebound in consumer confidence. Despite the ongoing Iran war and a dour mood in the U.S., the market's resilience was driven by strong corporate earnings, a potential resolution to the geopolitical crisis, and a positive outlook on the economy.
