KLNE aims to deliver 2x the daily returns of its underlying index, which is comprised of companies involved in the biofuels, ethanol, geothermal, hydroelectric, solar, and wind industries. Aside from holding companies that produce energy through these means, KLNE also includes companies that develop technology and equipment used in the process. Selected by the index committee, the fund is weighted by market-cap and exposure score subject to several constraints and reconstituted semi-annually. As a levered product, KLNE is not a buy-and-hold investment and should not be expected to provide index leverage returns greater than a one-day period.
