 Green Plains was soaring Wednesday after Jefferies upgraded the ethanol producer to buy from hold as the ethanol industry rebalances. Analyst Laurence Alexander, who raised his price target to 16 from 7, said Green Plains is likely to move from cost reductions to growth investments in the second half of the year and 2021 as the ethanol industry is already rebalancing, helped by a sharp recovery in gasoline demand. One of Green Plains long-standing competitive advantages has been its hedging strategy, Alexander said.
