Title: Nasdaq 100 Index Volatility: The Trade Desk's S&P 500 Inclusion and Market Shifts

July 2, 2025 - The Nasdaq 100 index opened with significant volatility on July 2, 2025, driven by the inclusion of The Trade Desk (NASDAQ:TTD) in the S&P 500 index. The digital advertising platform saw its stock jump 11.5% following the announcement [1]. This move comes as The Trade Desk is set to replace ANSYS Inc. (NASDAQ:ANSS), which is being acquired by Synopsys Inc. (NASDAQ:SNPS) [1].

The inclusion in the S&P 500 typically generates substantial buying pressure as index funds must purchase shares of newly added companies. The Trade Desk's addition is expected to boost its visibility and liquidity, potentially lowering its cost of capital. This is a significant milestone for the company, which operates in the Communication Services sector [1].

Meanwhile, other stocks reacted to the news. AppLovin Corp (NASDAQ:APP) shares fell 3.1%, while Robinhood Markets Inc (NASDAQ:HOOD) dropped 1.4%. Both companies had been considered potential candidates for S&P 500 inclusion [1].

Constellation Energy Corporation (CEG) ended the trading session at $325.99, demonstrating a +1.38% change from the preceding day's closing price. The stock outperformed the S&P 500, which registered a daily gain of 0.14%. Over the previous month, CEG witnessed an 8.3% gain, outperforming the Oils-Energy sector and the S&P 500 [2].

DoorDash (NASDAQ:DASH) saw its stock tumble 2.63% after Jefferies downgraded shares to Hold from Buy due to valuation concerns. The analysts cited a 120% premium to the Internet sector as the primary reason for the downgrade [3]. Despite this, DoorDash has shown resilience, with its stock up 43% year-to-date and approaching a new buy point [3].

Advanced Micro Devices (AMD) experienced a 7.4% increase, potentially driven by positive earnings reports or industry trends. However, the stock has lost 28.7% year-to-date [3].

In summary, the Nasdaq 100 index showed mixed results on July 2, 2025, with The Trade Desk's S&P 500 inclusion driving significant volatility. Investors should closely monitor the performance of these companies as they navigate market shifts and valuation changes.
