URA offers exposure to a broad range of companies involved in global uranium mining and the production of nuclear component that are pure-play or have large absolute revenues in the uranium industry. This includes those in extraction, refining, exploration, or manufacturing of equipment for the uranium and nuclear industries. The index is reconstituted semi-annually. Prior to May 1, 2018, the fund tracked the Solactive Global Uranium Index. The fund announced the underlying index will change to the Solactive Global Uranium & Nuclear Components Index during the third quarter of 2018.
