The investment seeks investment results that correspond (before fees and expenses) generally to the performance of its underlying index, the Solactive Junior Gold Miners Custom Factors Index (Ticker: SOLJGMFT). The Index aims to track the performance of small-capitalization gold companies whose stocks are listed on regulated exchanges. The Index uses a transparent, rules-based methodology that is designed to emphasize junior gold stocks with market capitalization between $200 million and $2 billion. The Index emphasizes junior gold producers with the strongest revenue growth and junior exploration companies with the strongest stock price momentum. The Index is reconstituted on a semi-annual basis, in November and May, to incorporate the latest factor scores into the selection and weighting process.
