Bloom Energy Surges on S&P 500 Inclusion While Trade Desk Drops

Bloom Energy (NYSE:BE) surged over 8% in early trading after being added to the S&P 500 index, effective September 21. The move is driven by mechanical demand from large-cap index funds rebalancing their portfolios rather than changes within Bloom itself. Conversely, The Trade Desk (NASDAQ:TTD) was removed from the S&P 500 and demoted to the SmallCap 600, triggering forced selling. TTD stock fell by about 2% as a result of this index reshuffle. Analysts noted that while other companies like FuelCell Energy and Plug Power have had strong year-to-date gains, only Bloom is currently benefiting from exclusive mechanical buying due to its S&P inclusion. UBS analyst Manav Gupta raised his price target for Bloom Energy to $325, citing the index addition as a significant catalyst. The company reported Q2 revenue of $1.07 billion—a 165% year-over-year increase—driven by strong demand from hyperscalers and neocloud operators.
