This ETF offers exposure to the residential and commercial real estate, mortgage finance, and savings associations sectors of the U.S. equity market. REM follows the FTSE NAREIT All Mortgage Capped Index, which has 50 holdings diversified evenly across small, mid, and large-cap equities, also allocating a little less than half of its assets to the financial services sector. Real estate has historically been embraced because of its ability to deliver excess returns during bull markets and low correlation with traditional stock and bond investments. REITs might appeal to investors seeking current income, as these trusts must distribute at least 90% of their income to investors, and offer an efficient way for investors to gain indirect exposure to real estate prices (as opposed to direct exposure gained through ownership of a residential property). VNQ is a cheaper and more liquid alternative available, while FRL boasts the lowest expense fee in this category.
