Shares of leading ethanol producer and distributor Pacific Ethanol (NASDAQ: PEIX) fell more than 13% last month despite the company reporting growth on multiple fronts during the first quarter of the year. In Q1, revenue and gallons sold increased 13% and 9%, respectively, over the year-ago period. That nudged shares up in the beginning of May, but shares resumed their year-to-date slide shortly after that, ending the month at a new low for 2017.
