QYLE pursues two investment objectives in one ticker, positive ESG exposure and income generation. The fund tracks an index that starts by screening out companies of the Nasdaq 100 Index with business activities that do not meet certain ESG criteria or those that have a high ESG risk rating, as determined by Sustainalytics. Companies determined out of compliance with the principles of the United Nations Global Compact are also excluded. Stocks selected are weighted by market-cap and adjusted by its Sustainalytics ESG Risk Rating Score. In addition to the long stock exposure, the fund writes (sells) one-month, at-the-money call options on the Nasdaq 100 Index. The options written are expected to be proportionally similar to the long exposure but may not be fully covered. While the strategy potentially generates income via the options premium, it places a drag on the appreciation potential. The index is rebalanced quarterly.
