This investment vehicle's primary objective is to track the overall performance, measured by total return, of the NASDAQ Junior Biotechnology Index, before accounting for any associated fees or expenses. The index itself is a rule-based compilation of U.S.-listed small-capitalization ("junior") biotechnology companies, carefully selected from the broader spectrum of businesses found within the NASDAQ Biotechnology Index. The fund typically implements a "replication" investment strategy, which means it generally acquires positions in all the component securities of its benchmark index, aiming to maintain their proportional weightings.
