Bloom Energy's 16.5% Friday drop was mechanical selling from its move out of the Russell 2000 into the Russell 1000, not a fundamental change. Funds tracking the Russell 2000 hold more assets, about $84B in IWM versus $48B in IWB, so the rebalance created heavy sell pressure into the close, including a 10% slide in the last hour. Its $253 closing price is a good value zone, since short-term moves are driven by flows while fundamentals drive the stock long term. x.comÂ
