Dow Jones, Nasdaq 100: Wall Street Eyes Quarter-End Finish at Record Highs

• Microsoft fell roughly 20% and Nvidia declined 13% in June as investors demand evidence of returns on hundreds of billions spent on AI chips, data centers, and infrastructure
• The Philadelphia Semiconductor Index surged 6% in June and is up 90% year-to-date, diverging from big tech losses and indicating capital rotation within AI toward component suppliers rather than end users
• The Nasdaq-100 is testing the critical 61.8% retracement level at 30,111.50, with a break above opening a path to all-time highs while failure could trigger a retreat to the 50-day moving average at 29,364.93

Market Summary: Wall Street Approaches Quarter-End at Record Highs

Key Market Performance:

Wall Street is closing out a strong first half of 2026, with major indices at or near record highs. Year-to-date gains include: Dow Jones +8.6%, S&P 500 +8%, and Nasdaq leading at +11.1%. Second quarter performance was even stronger, with the S&P 500 up nearly 14% and Nasdaq surging almost 20%.

Magnificent Seven Correction:

Despite overall market strength, the CNBC Magnificent Seven Index dropped 10% in June, losing $2.3 trillion in market capitalization. Notable declines include Microsoft (-20%), Nvidia (-13%), and both Apple and Amazon (-8%). The selloff reflects investor concerns about returns on massive AI infrastructure spending.

Sector Divergence:

The Philadelphia Semiconductor Index climbed 6% in June and has surged 90% year-to-date, even as big tech declined. This divergence suggests investors are rotating within the AI supply chain toward component manufacturers rather than the companies making large capital investments.

Technical Outlook:

The September E-mini Nasdaq-100 futures are testing the critical 61.8% retracement level at 30,111.50. A sustained move above could push the index to new all-time highs at 31,100. Key support sits at the 50-day moving average of 29,364.93.

Market Catalysts:

Monday's 1.18% S&P 500 rally followed a U.S.-Iran ceasefire agreement regarding the Strait of Hormuz. However, upcoming July earnings season will be crucial in determining whether AI spending produces tangible profits, representing a major test for big tech valuations.
