Shows the implied optimal allocations to listed U.S. equity REITs and private equity real estate funds following core, value add, and opportunistic strategies, based on net total returns reported for the historical period 1993q1-2013q3. The minimum-volatility real estate portfolio would have included nearly 5% in listed U.S. equity REITs. Private real estate return measures lag behind actual returns by about 4-5 quarters, producing a "temporal diversification" benefit: when real estate markets turn down, measured returns for private investments are usually still increasing; when measured returns on private real estate finally turn down, listed returns are often already rising. The chart shows an example of an implied optimal allocation for an 8.5% target long-term average net return. It also shows the real estate portfolio allocation that would have maximized risk-adjusted returns (Sharpe ratio) over the historical period with 39.1% invested in opportunistic real estate funds, 38.0% in core funds, and 23.0% invested in listed equity REITs. The reason this chart is not updated is that the NCREIF-Townsend Fund Indices for private equity real estate funds following value-add and opportunistic strategies were discontinued after 2013Q3.
