Observers, though, have pointed out that the REITs sector could gain momentum ahead as Real Estate will separate from Financials to become its own S&P 500 sector, which could help the new REITs sector attract greater inflows from underweight money managers.

The S&P Dow Jones Indices stated it would add an 11th sector to its Global Industry Classification Standard, creating a new Real Estate Sector from the Financial Sector. The changes to the S&P 500 index will be implemented after the close of business on September 16, 2016.

However, Goldman argued that it is not enough to put a buy rating on the REITs sector.

“Looking forward, we recommend a Neutral weighting to the Real Estate sector given slowing top-line revenue growth, average relative valuation, and risks from a higher interest rate environment,” Goldman said.
