Sprott Junior Gold Miners ETF(AMEX:SGDJ)

SGDJ offers exposure to equity in small-cap gold mining firms. These juniors have low gold production (developers) or none-as-yet (explorers). The weighting scheme starts with market-cap weights, and then adds or subtracts weight based on 12-month revenue growth for developers and 12-month price momentum for explorers. Firms with favorable scores receive more weight, while those with lower scores have weights removed, but apparently are still retained in the index. Maximum single position is 9% at rebalance (with additional RIC concentration screens). The index is reconstituted and rebalanced semi-annually. Note: Prior to July 22, 2019, the fund tracked the Sprott Zacks Junior Gold Miners Index.
