IWFL aims to provide 2x leveraged exposure to the US large-cap equity segment deemed more growth-oriented relative to the overall market. It is based on the total return version of the Russell 1000 Growth index, which includes firms that have higher price-to-book ratios and higher forecasted growth values. The fund also resets its leverage quarterly. As a levered product, IWDL is not a buy-and-hold investment and should not be expected to provide index leverage returns greater than a one-day period. Keep in mind this is an exchange-traded note, as such, investors also assume the credit risk of UBS. Index reconstitution is done annually.
