The investment seeks to provide investment results that closely correspond, before fees and expenses, to the performance of the Total 3D-Printing Index (index). The fund normally invests at least 80% of its total assets in securities that are included in the fund's benchmark index, depositary receipts representing securities included in the index or underlying stocks in respect of depositary receipts included in the index. The index is designed to track the price movements of stocks of companies involved in the 3D printing industry. The fund is non-diversified.
