is an acronym for Real Estate Investment Trust. And what is that?
http://www.investinreits.com/learn/reitstory.cfm REOC is an acronym for Real Estate Operating Company. REOCs are C-corps, not organized as REITs, so they pay corporate income tax on any dividends paid, and are not required to pay out at least 90% of their taxable earnings as dividends (as REITs are). RMS & RMZ are the tickers for the most-followed REIT indexes – the Morgan Stanley REIT Index. (The RMS is updated daily and includes dividends; the RMZ is updated constantly and is price-only.) There are numerous other REIT Indices, including S&P REIT, NAREIT Equity, and Wilshire REIT Index. The RMS is a total return index (i.e., dividends are added into the index’s value). As of this writing, it includes about 2/3 of all equity REITs. Healthcare REITs were originally excluded from the RMS, but were added in 2002. UPREIT is an acronym for Umbrella Partnership REIT, referring to a REIT structure created for tax advantage purposes. This thread has several in-depth posts discussing UPREITs: h
