Now that major indices have given real estate investment trusts their own Global Industry Classifications Standard sector designation, REITs-related exchange traded funds could improve as managers shift more assets into the area to bring their own allocations up to snuff.

For instance, investors can capture broad REITs exposure through ETFs like the Vanguard REIT ETF (NYSEArca: VNQ), iShares Dow Jones US Real Estate Index Fund (NYSEArca: IYR) and SPDR Dow Jones REIT ETF (NYSEArca: RWR). VNQ and RWR both exclude mortgage REITs and non-real-estate specialty REITs. IYR covers all domestic REITs.

VNQ has a 0.10% expense ratio and a 3.19% 12-month yield. IYR has a 0.45% expense ratio and a 3.45% 12-month yield, RWR has a 0.25% expense ratio and a 2.91% 12-month yield.

After the close of U.S. markets Monday, S&P Dow Jones Indices and MSCI (NYSE: MSCI) announced that real estate will become the eleventh Global Industry Classification Standard (GICS) sector. REITs will be split off from financials services to form its own sector, with a 2.5% total value of the S&P, reports John Authers for Financial Times.

With the new classification, active managers who follow the MSCI or S&P benchmarks may have to think about their allocations to better reflect performance levels compared to benchmark indices. Additionally, many institutions currently classify the sector as an alternative investment, so moving REITs into the mainstream may increase the asset class’ exposure.

Consequently, real estate investments could experience more interest, buying and potentially improved performance in the coming months ahead. The change is not imminent as the sector changes will occur after markets close on Aug. 31, 2016, but investors will likely shift sector weights in the meantime.
