This ETF offers exposure to real estate investment trusts within the U.S. equity market, an asset class that has been recently overlooked by many investors following the unprecedented housing crisis. PSR follows the FTSE NAREIT Equity REITs Index, which has just fewer than 50 holdings diversified primarily across mid and large-cap equities. 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). IYR is a cheaper and more liquid alternative available, while FRL boasts the lowest expense fee in this category.
