SLVR is designed to track an index of 30-50 companies engaged in silver mining and publicly traded closed-end trusts that hold physical silver. It primarily invests in firms that derive significant revenue from silver-related activities. The fund selects securities through a proprietary methodology, classifying issuers as growing Silver Producers, Developers, or Explorerscompanies involved in extracting silver, preparing mines, or searching for silver. Qualifying securities must have a Silver Intensity Score of at least 25%. Stocks are categorized into Group 1 for scores of at least 50% using unadjusted free float market cap, and Group 2 for scores between 25% and 50% using a theme-adjusted calculation. Weights are based on modified market-cap with adjustments to limit concentration, including a cap of 17.5% for physical silver. By rebalancing semi-annually, SLVR maintains exposure to companies that contribute to the silver industry while ensuring broad exposure to the segment.
