The Dow Jones Industrial Average climbed 115.01 points, or 0.23%, to close at 49,711.98 on Thursday, extending its winning streak to four consecutive sessions. The gain pushed the index closer to the 50,000 level. The broader S&P 500 and Nasdaq Composite also finished higher, with the tech-heavy Nasdaq leading gains on strength in AI-related names. Several Dow components reported results that exceeded Wall Street expectations, including Caterpillar, which raised guidance, and financial giants Goldman Sachs and JPMorgan Chase. Nvidia and other semiconductor names extended gains on demand for data center infrastructure. Markets benefited from signs of de-escalation in the Middle East, with Brent crude trading near $78 per barrel. The Federal Reserve's signals of patience on rate cuts were interpreted as constructive. The 10-year Treasury yield held steady around 4.35%. Nine of 11 S&P 500 sectors finished in positive territory, with industrials and financials leading the Dow's gain. Defensive sectors underperformed as investors rotated toward cyclical names.
