GMO publishes periodic real return forecasts for a variety of asset classes. Here is the latest: https://www.gmo.com/docs/default-source/research-and-commentary/strategies/asset-class-forecasts/gmo-7-year-asset-class-forecast-(3q2017).pdf?sfvrsn=3. (Free registration may be required.)
Selected highlights:
Stocks:
US Large -4.1% (per year)
US Small -2.9%
Int'l Large -0.7%
Int'l Small -1.4%
US Cash 0.1%
In the past, GMO has reported that it assumes that valuation will be equal to the long-term mean at the 7-year horizon. GMO assumes that the future mean is higher than the historical mean, but still lower than today; that accounts for the negative return forecasts.
I assume the future return will be current dividend plus 1.8% real eps growth (Shiller's 1881-present historical figure) minus some valuation haircut. The current PE10 is about 31.5 (https://www.gurufocus.com/shiller-PE.php) versus the long-term mean of 16.8. I think it's likely that the PE10 will dip below 16.8 at some point over the next 12 years, causing negative returns between here and there. Not sure if that's at 3 years, 7 years, 10 years, etc.
