SZK is a levered product that provides (-2x) daily inverse exposure to a market cap-weighted index representing the consumer staples sector of the S&P 500. The underlying index, which is an S&P Select Sector Index, includes food & staples retailing, food, beverage & tobacco, and household & personal products. The fund is not a buy-and-hold ETF, its a short-term tactical instrument. Like many levered funds, it promises -2x exposure only for one day. Over longer periods, returns can vary significantly from -2x exposure to its underlying index. Holding it for a period longer than that will introduce the effects of compounding, even if this is less pronounced in a non-leveraged product. Prior to March 20, 2023, the fund traded as the Proshares UltraShort Consumer Goods and tracked the Dow Jones U.S. Consumer Goods Index.
