ESUS makes a leveraged bullish bet on the MSCI USA ESG Focus Indexan index that holds large- and mid-cap companies exhibiting positive ESG characteristics, while maintaining a market-like risk and return profile. Eligible securities are initially screened to exclude firms involved in tobacco, controversial weapons, fossil fuel extraction, and thermal coal power. The portfolio is then optimized to maximize its exposure to ESG factors while staying true to a market-like exposure (subject to constraints). The underlying index rebalances quarterly. As a levered product with 2x factor that resets quarterly, the fund is not a buy-and-hold investment and should not be expected to provide index leverage return on a day-to-day basis. In addition, investors should note that ESUS is an ETN, and therefore carries the credit risk of the issuer, UBS.
