The Trade Desk booted from S&P 500 on 21 September after market cap crashes from $69B to $6.8B

The Trade Desk will leave the S&P 500 and join the S&P SmallCap 600 on 21 September as part of the quarterly index reshuffling. The advertising technology company's shares have plummeted from $141 to around $14, with its market capitalisation falling from a peak of $69 billion in 2024 to $6.78 billion. The company reported disappointing second-quarter 2026 results, with revenue increasing just 3% year-over-year to $715 million, missing analyst expectations of $751.4 million. Adjusted earnings per share came in at $0.34, below the expected $0.40. The Trade Desk guided for third-quarter revenue of at least $650 million, representing a 12% year-on-year decline. The index removal could trigger additional selling pressure as funds rebalance their portfolios.

The Trade Desk down 72% despite 19.6% operating margin and $1.1B net cash

The Trade Desk, an advertising technology firm, has seen its stock plummet 72% over twelve months to around $14.43, despite generating substantial cash flow. The company produced $850 million in free cash flow against a $6.8 billion market capitalisation and holds $1.1 billion in net cash. The markdown stems from stalled growth. Revenue grew just 3% year-over-year in the second quarter, with management lowering third-quarter guidance to at least $650 million, implying a potential decline. Consumer packaged goods and automotive clients, representing 25% of business, are shifting to cheaper advertising options amid economic pressures. However, international regions EMEA and APAC grew nearly 30% year-to-date. The company is launching new products including Audience Unlimited and platform upgrade Zuma to demonstrate value.

The Trade Desk falls from 40x gains to sub-4x as Amazon undercuts pricing

The Trade Desk shares reached $141.53 in December 2024, delivering a 40-fold return from Motley Fool's Rule Breakers recommendation in February 2017 at a split-adjusted $3.43. However, the investment firm issued a sell alert in August at $13.42, finishing less than fourfold. The company's competitive position deteriorated after Amazon launched a competing advertising platform priced at 1-2% of advertiser spending, compared to The Trade Desk's 12-15%. Amazon's share of programmatic ad spending surged from under one-tenth to one-fifth in 15 months. Three major agency holding companies reduced their commitments within two months. The Trade Desk's growth slowed from 22% in late 2024 to 3% this summer. In September, the company announced it would cut approximately 15% of its workforce without quantifying cost savings or providing management commentary.

The Trade Desk stock rises 3% after announcing 15% workforce cut, $39M-51M restructuring costs

The Trade Desk announced plans to cut roughly 15% of its workforce as part of a restructuring programme, sending shares up about 3% in early trading on Friday. The digital advertising company expects the job reductions to be largely completed during the third quarter of 2026. Management anticipates cash expenses of approximately $39 million to $51 million, primarily for severance and employee benefits. Some costs may be offset by a $4 million to $5 million reversal in stock-based compensation. The company will record the restructuring accrual in the third quarter. The Trade Desk noted final costs could differ from current estimates as the workforce plan unfolds. The initial share price reaction suggests investors view the restructuring as an effort to improve cost discipline.
