The VanEck Office and Commercial REIT ETF (DESK) endeavors to mirror, as accurately as possible, the financial results of the MarketVector US Listed Office and Commercial REITs Index. Its objective is to achieve the same price appreciation and income yield as the index, prior to the deduction of the ETF's operating costs. The index itself is formulated to provide a comprehensive measure of the collective performance of publicly traded U.S. real estate investment trusts that specialize in office and commercial properties.
