The Trade Desk stock (ISIN US88339J1051) has come under sustained pressure, with the shares down about 70 percent over the last year ahead of their removal from the S&P 500 on September 21, 2026, following a marked slowdown in revenue growth and shifting competitive dynamics.
Growth decelerates and index exit looms
According to an analysis of The Trade Desk’s performance, the company was added to the S&P 500 on July 18, 2025, when the stock closed at USD 80.21, but by September 10, 2026 the closing price had fallen to USD 13.97, illustrating a roughly 82.6 percent decline over that fourteen-month span as the business and valuation reset.
In the most recent reported quarter, The Trade Desk’s second-quarter 2026 revenue rose 3 percent year over year to USD 715 million, a sharp deceleration compared with growth rates above 20 percent in 2024, highlighting how advertiser spending has become more cautious and how competition is compressing take rates.
International expansion becomes more important
As noted in a recent fundamental review, The Trade Desk derived about 83 percent of its second-quarter 2026 revenue from the United States, with international markets contributing the remaining 17 percent, underscoring that growth opportunities in regions such as EMEA and APAC are increasingly important if the company is to reaccelerate overall revenue.
According to a Zacks research update dated September 11, 2026, The Trade Desk currently trades at a forward price-to-earnings multiple of 27.89 times versus an industry average of 19.97 times, while the Zacks Consensus Estimate for the company’s earnings has been revised downward over the past 60 days and the stock carries a Zacks Rank #4 (Sell), signaling more cautious analyst sentiment around near-term prospects.
Stock performance and upcoming earnings date
From a market perspective, the stock’s decline from USD 80.21 on July 18, 2025 to USD 13.97 on September 10, 2026 implies a very substantial loss of market value, and with the S&P 500 removal set for September 21, 2026, index-related selling pressure and portfolio rebalancing could continue to weigh on The Trade Desk stock until the change is fully implemented.
