Alternative energy mutual funds are continuing to recover from a slump which started in fall 2014. Annual returns range greatly, though, from a high of 15.6 percent for Brown Advisory Sustainable Growth (BIAWX), to a low of -15.8 percent for Guinness Atkinson Alternative Energy (GAAEX). The large 12-month drop by GAAEX was precipitated by painful losses in some of its top weighted holdings.
