SIJ provides geared inverse (-2x) exposure to the S&P Industrials Select Sector Index, a market cap-weighted index of US industrial companies drawn exclusively from the S&P 500. The index includes the following GICS industries: aerospace and defense, building products, construction and engineering, electrical equipment, industrial conglomerates, machinery, trading companies and distributors, commercial services and supplies, professional services, air freight and logistics, passenger airlines, marine and ground transportation, and transportation infrastructure. SIJ is designed as a short-term trading vehicle, not a long-term investment. It holds swap agreements and resets on a daily basis. As a result, long-term returns could materially differ from those of the underlying index due to daily compounding. Prior to March 20, 2023, the fund tracked the Dow Jones US Industrials Index.
