AI Propels Bloom Energy Stock Straight to Megacap Territory -- WSJ

Dow Jones
Jun 01

By James Mackintosh

For the first time since the 2008 global financial crisis, a stock has jumped straight from the small-cap ranks to the mega-capitalization segment of Russell indexes-driven by excitement about artificial intelligence.

Bloom Energy, a fuel-cell producer now harnessing its units to power data centers, has qualified for the Russell Top 200 index at the June rebalance following a 14-fold rise in its shares over the past year. It had previously languished in the small-cap Russell 2000 index.

Before 2008, the data is harder to analyze. The rebalance of the Russell index after close on June 26 is typically one of the highest-volume trading days of the year due to the trillions of dollars that track the indexes.
