Saw this on Yahoo and makes some sense as to why we are getting hammered right now. Huge inflows have gone into the global clean energy funds and some companies now have too be a share of the funds assets and therefore have to be sold off to rebalance the fund. Hedge funds had the heads up on this and shorted the stocks they knew would be forced to sell. Now guess who is the largest holding? https://etfdb.com/etf/ICLN/#holdings Yep, Plug Power and this is likely to be over soon and after that the pressure should be coming off a bit, but now makes more sense as to why some of the largest EV and FC stocks are selling off.
