This ETF offers exposure to the residential real estate, healthcare, and self-storage sectors of the U.S. equity market. REZ follows the FTSE NAREIT All Residential Capped Index, which has fewer than 40 holdings diversified primarily across mid-cap equities, while exposure to large and small-cap companies is also included. 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, but broad-based alternative, while FRL boasts the lowest expense fee in this category.
