June 30, 2026, 12:39 PM EDT. Plug Power Inc. shares added 4.63% to $2.71 after the stock moved to the Russell 2000 Growth index, leaving the Value side as part of the June 2026 Russell reshuffle. Plug also met the June 30 deadline to sell its Project Gateway stake to Stream Data Centers, a deal seen delivering $132.5 million to $142 million. That total is about 3.7% to 3.9% of Plug's market cap and will help lift cash. Volume was just 31% of the 65-day average, while short interest sat high at 25.5% of float, signaling big bearish positioning. The reshuffle shifts what kinds of funds might own Plug, but doesn't change the underlying business.
