S&P 500 hits intraday record high of 6,565 points.

The S&P 500 index reached an intraday record high of 6,565 points on September 10, 2025, marking a significant milestone in the stock market's performance. This achievement comes amidst a backdrop of strong gains across major indices, driven by robust performances from tech and fintech stocks, as well as positive developments in the energy sector.

The Nasdaq Composite, for instance, gained 0.8%, reaching a new intraday record of 21,868 points, propelled by the strength of AI and semiconductor stocks. The S&P 500 rose 0.4%, while the Dow Jones Industrial Average edged up 0.2%, adding 67 points. Small-cap stocks, represented by the Russell 2000, underperformed slightly, falling 0.3%, but remained above key short-term moving averages.

Key drivers behind this performance include the inclusion of Robinhood and AppLovin in the S&P 500 index, which has boosted investor confidence and led to significant gains. Robinhood (HOOD) surged nearly 15%, rebounding above its 10-week moving average, while AppLovin (APP) climbed roughly 10%, with gains of about 69% year-to-date in 2025. These stocks will join the S&P 500 on September 22, replacing Caesars Entertainment (CZR) and MarketAxess (MKTX).

Additionally, the energy sector, particularly oil and gas pipeline and storage companies, has shown resilience. Kinder Morgan (KMI) closed at $27.38, moving +2.78% from the previous trading session, outperforming the S&P 500's 0.3% gain. Kinder Morgan's stock has appreciated by 0.3% over the past month, underperforming the Oils-Energy sector's gain of 1.33%, but still demonstrating positive momentum.

Investors are closely monitoring upcoming inflation reports and Federal Reserve signals, which could shape rate-cut expectations. The 10-year Treasury yield continued to fall, dipping two basis points to 4.07%, supporting equities and signaling cautious optimism among investors.

Market sentiment remains positive, with the S&P 500 and Nasdaq gains reflecting optimism around passive fund inflows from index inclusion, tech-led growth, and AI-driven momentum. However, inflation data and Fed rate decisions could trigger short-term volatility. Energy, telecom, and geopolitical developments will also impact sector-specific performance.

Traders should monitor Treasury yields, CPI/PPI releases, and earnings updates from Adobe, Oracle, and Kroger for broader market cues. The S&P 500's intraday record high underscores the market's resilience and the ongoing influence of various factors shaping the financial landscape.
