The Fund seeks to track the price and yield performance, before fees and expenses of the WisdomTree Battery Solutions Index. The Index is designed to track the performance of companies primarily involved in battery and energy storage solutions (BESS). The Index excludes companies based on environmental, social and governance criteria. The Index utilises an intensity rating which is developed by WisdomTree Investments Inc in collaboration with third party specialists in BESS (Intensity Rating). The Index also utilises a composite risk score screening (CRS) which is made up of two factors (quality and momentum) each carrying an equal weighting.
