Down 63%, Should You Buy the Dip on The Trade Desk Stock?

The Trade Desk (TTD) reported Q3 2025 results that surpassed expectations, with revenue up 18% to $739 million and non-GAAP EPS rising 10% to $0.45. However, the company's Q4 revenue guidance of $840 million indicates a further growth deceleration to 13% year-over-year, now trailing the programmatic advertising market's projected 23% annual growth. This slowdown, coupled with intensifying competition from Amazon in connected TV advertising and an industry oversupply of ad inventory, raises concerns about TTD's premium valuation of 61x trailing earnings, suggesting potential continued pressure on the stock despite its 63% decline this year.

Analysis

The Trade Desk (TTD) reported Q3 2025 revenue of $739 million, an 18% year-over-year increase, and non-GAAP EPS of $0.45, both exceeding expectations. However, the company's Q4 revenue guidance of $840 million implies a significant growth deceleration to just 13% year-over-year. This projected growth rate now lags the broader programmatic advertising market's estimated 23% annual expansion through 2030, indicating potential market share erosion.

Despite a 63% stock decline in 2025, TTD maintains a premium valuation at 61 times trailing earnings, substantially higher than the Nasdaq-100's 34x P/E multiple. This elevated multiple appears unjustified given the decelerating growth and intensifying competitive pressures. Amazon's aggressive expansion into connected TV advertising, including recent deals with Disney and Netflix, poses a direct threat, challenging TTD's market position.

Further exacerbating TTD's challenges is an industry-wide oversupply of ad inventory, where "supply is significantly outstripping demand." This dynamic makes it harder for TTD to attract advertisers, as clients can be more selective, impacting the company's ability to drive revenue growth. The combination of slowing growth, competitive threats, and market saturation suggests continued pressure on TTD's earnings trajectory.

Key Decisions for Investors

• Investors should exercise caution, as The Trade Desk's premium valuation of 61x trailing earnings appears unjustified given its decelerating growth to 13% and significant competitive headwinds.
• Consider re-evaluating existing positions or avoiding new entries, considering the company's potential market share loss to Amazon in connected TV advertising and the broader industry oversupply of ad inventory.
• Monitor TTD's ability to reaccelerate growth and defend its market position against larger rivals, as current trends suggest continued pressure on its stock price.
