Questions emerge as REIT rally hits year three 	 	                                        By Murray Coleman

                                   --REIT valuations are seen as rather rich for the real-estate sector  							
                                   --Following a rise in correlation last year, REITs and S&P 500 may be starting to break out of lockstep  							
                                   --Some advisers say REIT ETFs are still a good way to diversify  portfolios  							
                                   SAN FRANCISCO (MarketWatch) -- As commercial real estate enters a third  year of recovery, exchange-traded funds focusing on that corner of the  market seem to be losing some of their appeal.  							
                                   Not only are relative valuations looking stretched, but  real-estate-investment trusts have been moving more in lockstep with  blue-chip stocks. A rise in correlation last year between REITs and the  Standard & Poor's 500 Index is raising questions about their  diversification benefits to long-term investors.  							
                                   During the most recent financial crisis, REITs fell just as hard as the SPDR S&P 500                  				    (NAR:SPY) 			      , which tracks the index bearing its name. The most liquid ETF among  REITs, the iShares Dow Jones U.S. Real Estate Index Fund                   				    (NAR:IYR) 			      , slid almost 40% in 2008. SPY, the industry's biggest ETF in terms of assets, dropped nearly 37% that year.  							
                                   When markets started rallying, REITs took off as well. Since early March  2009, IYR's shares have more than tripled. In that same period, SPY had  more than doubled through Wednesday.  							
                                   Since yields move inversely to prices, the IYR's outperformance has  resulted in a shrinking in its distribution yield to around 4%. While  that is almost double the payout for the iShares Barclays 7-10 Year  Treasury Bond Fund                  				    (NAR:IEF) 			      , such a yield still represents a drop from its 20-year average yield of  6.5%, as tracked by the FTSE NAREIT Composite REITs Index.  							
                                   The advance by REITs also has made the sector appear rather pricey by  some measures. The 12-month trailing price-earnings ratio for the  S&P 500 is around 13.9, down from its average since 1996 of 19.5,  according to Sage Advisory Services. At the same time, the firm  estimated, REITs were trading at a 19.4 price-to-funds-from-operations  multiple, a financial metric for such real-estate firms. By comparison,  the category's long-term average was about 14.5.  							
                                   "You've got to really like commercial real estate to buy them at this  point in the cycle," said Rob Williams, the Austin, Texas, advisory  firm's research director.  							
                                   An expanding chorus of analysts has been sounding cautionary notes that  REIT funds aren't providing as much diversification as in the past. At  issue are correlation rates, which compare directional performance  trends of specific funds against the broader market. A month ago, the  popular IYR was at 83 on a scale in which 100 represents equal tandem  with the S&P 500.  							
                                   But correlations tend to ebb and flow over time, noted Mark Armbruster,  an adviser based in Rochester, N.Y. He said the benchmark underlying IYR  has bounced over longer periods from a correlation in the 50s to a  90-plus level.  							
                                   Along those lines, the iShares REIT fund has started showing signs of  returning to more traditional levels. Earlier this week, ConvergEx Group  estimated IYR's correlation had dropped to 58 in the past 30 trading  days.  							
                                   Armbruster, who is president of Armbruster Capital Management, said  while he isn't adding to existing positions, REITs remain a core  allocation in client portfolios.  							
                                   "Everything went down together and now everything's basically recovering  together," Armbruster said. "But we believe that the economic drivers  for commercial real estate are unique enough so that the historical  diversification benefits of holding REITs will return over time."
