Trade Desk Falls 4%
Trade Desk stock is at $13.34, down 4% in Tuesday morning trading, and it’s down 65% year to date.
Index Rebalance Pressures
S&P Dow Jones Indices announced on September 4 that The Trade Desk would leave the S&P 500 in the September quarterly rebalance and move to the S&P SmallCap 600.
Peer Group Reactions
Magnite stock is at $24.55, down 3%, moving with Trade Desk stock on the same session, while AppLovin stock is at $327.95, down 0.67%.
Programmatic Repricing
The split shows programmatic ad-tech is being repriced unevenly, with Magnite falling alongside Trade Desk but AppLovin holding steady.
Index Exit Mechanics

Passive funds benchmarked to the S&P 500 have to sell the name mechanically, and the pressure that creates is finite once those flows clear.
Value Case
Trade Desk stock now trades at a trailing price-to-earnings ratio of 13.45x, with customer retention rates above 95% for more than a decade.
What to Watch Next
Index rebalance flows eventually exhaust themselves, so Trade Desk stock’s next move depends on whether real-money buyers step in at a depressed multiple.
The bottom line
Trade Desk stock drops 4% after S&P 500 index exit, with Magnite falling 3% and AppLovin barely moving as programmatic ad-tech reprices unevenly.
