ProShares UltraShort Real Estate seeks daily investment results, before fees and expenses, that correspond to twice (200%) the inverse (opposite) of the daily performance of the Dow Jones U.S. Real Estate Index. The Dow Jones U.S. Real Estate Index http://www.djindexes.com/mdsidx/downloads/fact_info/USRealEstate_info.pdf measures the performance of the real estate industry of the U.S. equity market. Component companies include those that invest directly or indirectly through development, management or ownership of shopping malls, apartment buildings and housing developments; and real estate investment trusts ("REITs") that invest in apartments, office and retail properties. REITs are passive investment vehicles that invest primarily in income-producing real estate or real estate related loans or interests. It is not possible to invest directly in an index. If you are negative about commercial real estate, this is the ETF for you. If not, URE should be your choice. See #board-14698
