QULL offers 2x the daily performance of the MSCI USA Sector Neutral Quality Index, an index of large- and mid-cap US securities with the highest quality scores relative to its peers within the same industry group. The underlying index starts with assigning a quality score to MSCI USA Index (parent index) constituents within each GICS sector based on three fundamental factors:return on equity, debt to equity and earnings variability. Securities with the highest quality scores are selected and weighted by the product of their market cap weight in the parent index and their quality score. Each individual security is capped at 5% weight. As a levered product with quarterly resets, QULL is designed as a short-term trading tool and not a long-term investment vehicle. As a result, long-term returns could materially differ from those of the underlying index due to compounding. In addition, keep in mind QULL is an exchange-traded note, holders are subject to the credit risk of UBS.
